- System Specification - 6.5.1 Pressure Reducing Valves As supplied by GF Piping Systems reduces the pressure within the system to a pre- set value. By using the differential pressure, the pressure reducing valve adjusts itself to the set working pressure. The outlet pressure (working pressure) is not directly related to the inlet pressure. If the outlet pressure increases above the set value, the diaphragm is lifted against the spring force. If the outlet pressure falls below the set value, the diaphragm is pressed down by the spring force. The pressure reducing valve begins to close/open until a state of equilibrium is re-established; in other words, the outlet pressure remains constant irrespective of an increasing or decreasing inlet pressure.

- System Specification - 6.7 Servo-assisted Solenoid Valves Supplied by GF Piping Systems serves to regulate and control fluids, if no compressed air is available or unwanted. They are used for miscellaneous functions, e.g. opening, shutting, dosing, distributing and mixing. Opening large orifices using the direct-acting method would require enormous and expensive coils. Servo assisted valves use the power of the fluid to open the flow channel by controlling a small pilot channel to alter the forces on a larger main seal. A Δp 0.5 bar is mandatory with servo-assisted valves. • Type, 165, sizes DN10-50 6.8 Ventilating- and Bleed Valves Ventilating- and Bleed valves are not offered in SYGEF Plus (PVDF HP). 7. Welding and assembly All butt fusion fittings and valves in SYGEF Plus (PVDF-HP) shall be manufactured with laying lengths designed for use with fusion machines IR-63 Plus, IR-225 Plus, IR-315 Plus and IR-450 from GF Piping Systems, providing welds with increased mechanical and chemical stability than conventional welding methods. The IR Plus fusion machines use overlap controlled non-contact radiant heating. The cooling time for is calculated on the basis of ambient temperature and the bead surface temperature for uniform reproducible weld beads for easy weld bead inspection. To increase the cooling capacity, an additional cooling fan is included in the IR-225 Plus and IR-315 Plus. Only authorised welders by GF Piping Systems are allowed to perform fusion on the IR Plus machines. As an alternative to IR fusion, conventional butt fusion according to DVS 2207-15 may be used, preferably with automated CNC controllers and weld recorders. Special care needs to be taken to prevent the pipe and fitting ends from sticking to the heater plate. The BCF fusion technology joins SYGEF Plus (PVDF-HP) piping components of dimensions from DN20-110 without any irregularities, beads or crevices. The extremely compact fusion machine, which is also ideal for on-site fusion, is very reliable, easy to handle and creates reproducible and very strong fusion welds. Only authorized welders by GF Piping Systems are allowed to perform fusion on the BCF Plus machines manufactured by GF Piping Systems. The welding and the installation should be in accordance with GF Piping Systems Guide to the Installation and Use of Plastic Pipeline.

- System Specification - 8. Measurement & Control / Instrumentation The following parameters can be measured (Sensors), indicated and/ or transmitted (transmitters) to PLC, PC and other Data Acquisition Systems. All products comply with the CE standard. Parameter Technology Compatible liquids (*) Flow Paddlewheel clean liquids Rotameter clean liquids Magmeter contaminated liquids Level Hydrostatic/Ultrasonic/Radar all liquids pH-ORP Glas electrodes all liquids Conductivity Contact all liquids Pressure Piezoresistive all liquids Temperature Pt1000 all liquids (*) please check first the sensors limitations in material, pressure and temperature (data sheet) and chemical resistance list 8.1 Sensors The sensors listed hereafter will transfer the measured value to a Transmitter, to indicate the measured value and allowing simple calibration and maintenance of the devices. Alternatively the measured values of the sensors can be sent directly to a PLC, PC or other local made electronics using either an analogue signal (4-20 mA, open collector or sinusoidal voltage) or a digital signal called S3L. 8.1.1 Installation Fittings Depending on the sensor type, special installation fittings shall be used for connection to the pipeline: Installation T-Fitting sizes d20-63 with double true union in PP, Wafer fitting made out of PP-H in sizes d75–315 and weld-o-let made out of PE100 in sizes d75–630. Sensor thread connection shall be 1¼" NPSM. 8.1.2 Flow sensors 8.1.2.1 Paddlewheel sensors Sinusoidal sensors: This sensor requires no external power source to produce a signal. Internal to the body of the sensor is a wire coil which when excited by the rotor assembly produces a small sinusoidal signal. The rotor assembly consists of four paddles; inserted into each of the paddles of the rotor are magnets. As liquid flows past the rotor assembly it rotates each of the four paddles produces a sine wave signal as it passes the centre of the body (two paddles of the rotor produces a full AC sine wave). The sensors produce a signal output which is proportional to the flow rate. A K-factor (number of pulses generated by the sensor System Specification SYGEF Plus (PVDF-HP) page 13/ 20 Schaffhausen, June 2018

- System Specification - per 1 liter or 1 gallon of fluid the sensor) is used to define the size of the pipe that the sensor is inserted into. Hall Effect sensors: Internal to the manufacturer body is an open collector relay. The sensor is supplied with a voltage from the transmitters or an external power supply ranging from 5 to 24 volts. This voltage is switched through the open collector relay as the paddlewheel (rotor) of the sensor rotates. The sensor’s rotor assembly has four paddles. Inserted in two of the paddles is a magnet. As the paddles pass the centre of the sensors body, the magnetic field switches the open collector relay on and off which generates a square wave pulse. Two pulses indicates a complete rotation (on/off cycle) of the open collector relay. The pulse output is directly proportional to the fluid velocity. A K- factor (number of pulses generated by the sensor per 1 liter or 1 gallon of fluid passing the sensor) is used to define the size of the pipe that the sensor is inserted into. 8.1.2.2 Rotameters As supplied by manufacturer are radially installed dismountable meters for flow rate measuring in industrial piping applications. If needed, minimum or maximum flow can also be monitored via limit switches. Also, analogue flow measurement with a 4…20 mA Signal is possible. The working principle of the rotameter is based in gravity and equilibrium of forces. If a medium flows upwards at a sufficient flow rate through the vertically mounted taper tube, the float is raised to the point at which a state of equilibrium sets in between the lifting force of the medium and the weight of the float. Since the mean rate of flow is proportional to the quantity flowing through per unit of time, this state of equilibrium corresponds to the measurement of the instantaneous flow rate. Following types and sizes are available: • Length 165, 185, 200, DN10–32mm • Length 335, DN25 –65mm • Length 350, DN25 –65mm 8.1.2.3 Magmeter The Magmeter sensor consists of two metallic pins that produce a small magnetic field across the inside of the pipe. The The Magmeter measures the velocity of a conductive liquid (20 μS or greater) as it moves across the magnetic field produced by the Magmeter. A voltage occurs on the sensor tips, which is directly proportional to the flow rate of the fluid. The magnetic signal is conditioned and translated in to a pulse signal. A K-factor (number of pulses generated by the sensor per 1 liter or 1 gallon of fluid passing the sensor) is used to define the size of the pipe that the System Specification SYGEF Plus (PVDF-HP) page 14/ 20 Schaffhausen, June 2018

- System Specification - sensor is inserted into. The Magmeter is offered as a blind frequency, 4-20 mA or digital S3L output, or with integral display and control relays. 8.1.2.4 Ultrasonic Flowmeter They are transit time ultrasonic flow meter designed to work with clamp-on transducers, to provide accurate measurement of liquid flowing within a closed pipe, without the need for any mechanical parts to be inserted through the pipe wall or to protrude into the flow system. It takes just a few minutes to install and there is no need to shut down flow or drain the system! From process control in industrial applications, to water management from raw to deionized water for fixed installation and for portable flow monitoring cover a wide spectrum of flow monitoring and process control in many industries. Using ultrasonic transit time techniques enables to be used with pipes having an outside diameter range d13-2000 as standard and up to d5000 as an option. The instruments will also operate over a wide range of fluid temperatures. All of the Ultrasonic Flowmeters should have the same basic features. However, the standard can also perform data logging and allows site details and flow data to be reordered with a memory, that shall be able to log more than 150.000 separate readings. The standard shall be also capable of downloading the stored data via the USB or RS232 interface to the Portagraph software supplied with the unit. 8.2 Level Sensor 8.2.1 Hydrostatic Level Sensors Hydrostatic pressure is the pressure exerted on a column of fluid by the weight of the fluid above it. Internal to the PVDF sensor body is a ceramic diaphragm sensor and capillary tube/cable assembly. The ceramic diaphragm sensor exposed to the fluid senses the hydrostatic pressure of the fluid and compares the pressure to the atmospheric pressure monitored the capillary tube/cable assembly. The hydrostatic level sensor only senses the hydrostatic pressure of the fluid. The Level Sensor is offered as a blind output 4-20 mA or digital S3L output connected Transmitter. 8.2.2 Ultrasonic Level Sensors Ultrasonic level sensors are non-contact devices, using the travel time of sound and its reflection, for measuring the distance to a liquid or solid surface. Based on this information, GF Piping Systems sensors are capable of calculating a liquid level or volume. Their outstanding narrow 5° beam, allow reliable measurement even at the presence of disturbing objects or when space is limited. The GF Piping Systems portfolio contains sensing ranges 4 m, 6 m and 15 m. Sensors with integrated display or blind sensors are available and provide 4-20 mA, HART protocol or relay outputs. GF Piping Systems ultrasonic level sensors are System Specification SYGEF Plus (PVDF-HP) page 15/ 20 Schaffhausen, June 2018

- System Specification - compatible with GF Piping Systems transmitters, indicators, controllers and valve actuators. 8.3 Radar 8.3.1 Radar The 25 GHz (K-band) Pulse Radars are the most progressive non-contact level transmitters for industrial processes. With an excellent accuracy, compact antennas and a user-friendly set-up the 2290 is an effective, simple, low cost choice for demanding level applications. GF’s new K-band radar featuring 3 mm (0.1inch) accuracy and short dead band excels with its robust full plastic housing. Its antenna range incorporates a stainless steel horn and enclosed plastic tube choices. The enclosed antenna versions can be replaced without removing the antenna enclosure from the process. Local programming is aided by a plug-in display module. The signal processing algorithm of the 2290 is based on years of experience with non- contact level measurement making it an excellent choice for applications simple and challenging alike. Process enclosures are available in PTFE, PP & PE. 8.3.2 Radar With its ability to read accurately when other non-contacting or invasive methods fail, the guided level transmitter using GWR (guided wave radar) is the solution to your level needs. The radar signal is sent down the probe assembly eliminating the interferences caused by low dielectric liquids, heavy fuming, slightly conductive foams, internal tank obstructions, etc. By focusing its energy along the probe can be installed in tanks with limited space. It is also less sensitive to turbulence that would normally upset the readings in ultrasonic and unguided radar technologies. The probes are also available as coated options in FEP & PFA. 8.4 Point Level 8.4.1 Point Level Switches The GF Piping Systems portfolio of point level switches contains various different detection technologies, to provide a solution for various liquids and application requirements. • Vibration Forks detect a liquid level with two vibrating stainless steel wings. In air they vibrate with a specific, calibrated frequency. By the contact with a liquid the frequency changes which forces an electrical output to switch. GF Piping Systems vibration forks are equipped with digital PNP/NPN or relay output. Versions with ATEX or WHG approval are available. System Specification SYGEF Plus (PVDF-HP) page 16/ 20 Schaffhausen, June 2018

- System Specification - • Conductive Multipoint Switch contains up to 5 stainless steel electrodes, which allow to detect 4 different liquid levels in a tank. Up to 2 external relay pairs allow to switch pumps or valves. GF Piping Systems conductive multipoint switches work with liquids of min. 10µS conductivity. Their four-in-one design allows fast installation and provides attractive solutions concerning costs. • Guided Float Switches are equipped with an air filled float with embedded magnet. Rising liquid lifts up the float. The magnetic field forces a reed contact to switch. GF Piping Systems guided float switches are available in PP and PVDF to provide best chemical compatibility to corrosive liquids. • Ultrasonic Gap Switches are equipped with an ultrasonic transducer and receiver in their fork tips. Based on the switch design, the sound waves are damped in air. Thus the output is disabled. In contact with liquid the sound waves start to travel from transmitter to receiver, which enables the output. GF Piping Systems ultrasonic gap switches provide an electronic relay output which allows to control pumps and valves. Thanks to their PPS full-plastic body they provide a very high resistance against mechanical impacts and corrosive liquids. They work with no moving parts, so they do not require any maintenance. • Float Switches are primarily used in open basins and pump shafts for detecting liquid level. In an empty tank they hang in vertical position, attached to the tank wall at their cable. Rising liquid carry them on the liquid surface. At an angle of approximately 45° an integrated switch is enabled. GF Piping Systems float switches are double chambered and equipped with a mercury- fee switch. Hence they may be used for drinking and for waste water applications. 8.5 Analytic 8.5.1 pH Sensors All pH sensors are constructed commonly called combination electrodes. The measuring cell is constructed of hydrogen sensitive glass that can detect the concentration of hydrogen ions (+H) in a solution. The concentration of +H ions directly determines the pH of the fluid. The reference cell is used to provide a stable reference signal. The pH signal is measured against the stable reference signal. The reference junction allows the reference cell to come in contact with the fluid being measured. The measured signals are then conditioned and sent as a blind 4-20 mA or as a digital S3L signal Transmitter. System Specification SYGEF Plus (PVDF-HP) page 17/ 20 Schaffhausen, June 2018

- System Specification - 8.5.2 ORP Sensors All ORP sensors are constructed similar to the pH sensors, except that a noble metal like platinum or gold replaces the silver chloride element of the measuring and reference cell of the pH electrode. Temperature compensation is not used in ORP measurements as well. ORP is an abbreviation for Oxidation-Reduction Potential. Oxidation is a term used to denote the occurrence of a molecule losing an electron. Reduction occurs as a molecule gains an electron. The “potential” is simply an indication of a solution’s propensity to contribute or accept electrons. ORP reactions (sometimes referred to as REDOX) always take place simultaneously. There is never oxidation without reduction, and ORP electrodes are used to detect electrons exchanged by molecules as these reactions occur. The measured signals are then conditioned and sent as a blind 4-20 mA or as a digital S3L signal to Transmitter. 8.5.3 Conductivity Sensors All Conductivity sensors are manufactured using two stainless steel electrodes. Alternative materials are available in case of chemical incompatibility. Conductivity sensors measure the ability of a fluid to conduct an electrical current between two electrodes. The proper term for this ability of a solution is electrolytic conductivity, since only ions conduct electric current in solution. Electrolytic conductivity (or simply conductivity) is therefore an indirect measure of the ionic concentration of a solution. Generally, conductivity increases and decreases with the concentration of ions. Most conductivity electrodes consist of two measuring half-cells. The geometry of the half-cells can be tailored to provide highly accurate measurements over a specific conductivity range. Cell constants help to describe electrode geometry for the purpose of selecting the appropriate electrode for a given application. A cell constant is defined as the length between the two halfcells divided by the area of the cells. All conductivity sensors have a temperature compensation circuits in order to increase the sensors accuracy. The measured signals are then conditioned and sent as a blind 4-20 mA or as a digital S3L signal to the Transmitter. System Specification SYGEF Plus (PVDF-HP) page 18/ 20 Schaffhausen, June 2018

- System Specification - 8.6 Multi Parameter Instruments 8.6.1 Transmitters The Transmitter should provide a single channel interface for many different parameters including Flow, pH/ORP, Conductivity/Resistivity, Salinity, Pressure, Temperature, Level and other sensors that output a 4 to 20 mA signal. The display shows separate lines for units, main and secondary measurements as well as a dial- type digital bar graph. The transmitter is offered in both panel or field mount versions. Both configurations can run on 12 to 32 VDC power (24 VDC nominal). The transmitter can also be loop powered with compatible sensors. Derived measurements include difference, sum, ratio, percent recovery, percent rejection, percent passage and BTU. The menu system can be programmed to display in multi-languages including English, German, French, Spanish, Italian, and Portuguese. • 2,4 or 6 sensor input (Flow, Level, pH-ORP, Conductivity, Pressure Temperature) • 0,2 or 4 analogue output (4-20 mA or 0-10 Volts) • 0,2,4,6 or 8 relay output • Power supply 12-30 VDC or 110-230 VAC 8.7 Batch Control A batch controller shall allow batching a pre-selected quantity of liquid. After selection of the quantity to be dosed, a start signal (local or remote) will close a batch controller contact to energize or de-energize a valve and/or switch on a pump. The batch controller count the pulses coming from any sensor with frequency output and stop the batch process as the pre-selected quantity is reached. Advanced features include a user-set security code, an automatic calibration option, and overrun compensation. The batch process is repeatable and is designed for intensive industrial applications.
