- System Specification - 8.1.2 Flow sensors 8.1.2.1 Paddlewheel sensors 515 and 525 sensors: All sensors of this family are “sinusoidal” sensors. This sensor from Georg Fischer Piping Systems Signet 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 as manufactured by Georg Fischer Piping Systems Signet produce a signal output which is proportional to the flow rate. A K-factor (number of pulses generated by the sensor per 1 litre or 1 gallon of fluid the sensor) is used to define the size of the pipe that the sensor is inserted into. 3-2536 and 3-2537 sensors: All sensors of this family of sensors are “Hall Effect” sensors. Internal to the Georg Fischer Piping Systems Signet sensors body is an open collector relay. The sensor is supplied with a voltage from the 3-8550 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 as manufactured by Georg Fischer Piping Systems Signet. Two pulses indicate 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 litre 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 Rotameters, as supplied by Georg Fischer Piping Systems, 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 4-20mA 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 System Specification ABS BS Inch page 13/ 19 Schaffhausen, January 2015
Page14

- System Specification - 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: • Type SK, DN10-65 • Type 335, DN25-65 • Type 350, DN25-65 8.1.2.3 Magmeter The Magmeter sensor from Georg Fischer Piping Systems Signet consists of two metallic pins that produce a small magnetic field across the inside of the pipe. The Magmeter measures the velocity of a conductive liquid (20 µS or greater) as it moves across the magnetic field. 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 litre or 1 gallon) is used to calculate the flow volume. The Magmeter of Georg Fischer Piping Systems Signet is offered as a blind frequency, 4-20 mA or digital S3L signal, or with integral display and control relays. 8.1.2.4 Ultrasonic Flowmeter The U3000/4000, the PF220/330 and the U1000 from Georg Fischer Piping Systems are transit time ultrasonic flow meters, 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, the Ultraflow U1000/U3000/U4000 for fixed installation and the Portaflow PF220/330 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 from d13 to d2000 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 have the same basic features. However, the standard U4000 and PF330 can also perform data logging and allows site details and flow data to be reordered with a memory, that is able to log more than 150 000 separate readings. The standard U4000 and PF330 is also capable of downloading the stored data via the USB or RS232 interface to the Portagraph software supplied with the unit. 8.1.3 Level Sensors and Level Switches System Specification ABS BS Inch page 14/ 19 Schaffhausen, January 2015
Page15

- System Specification - 8.1.3.1 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 Georg Fischer Piping Systems Signet 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 from Georg Fischer Piping Systems Signet 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 to the Georg Fischer Piping Systems Signet Transmitter unit. 8.1.3.2 Ultrasonic Level Sensors (Series 2260 / 227 0) 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, Georg Fischer 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 Georg Fischer 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. Georg Fischer Piping Systems ultrasonic level sensors are compatible with Georg Fischer Piping Systems transmitters, indicators, controllers and valve actuators. 8.1.3.3 Point Level Switches (Series 2280) The Georg Fischer Piping Systems portfolio of point level switches contains various different detection technologies, to provide a solution for various liquids and application requirements. • Type 2280 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. Georg Fischer Piping Systems vibration forks are equipped with digital PNP/NPN or relay output. Versions with ATEX or WHG approval are available. • Type 2281 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. Georg Fischer 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. System Specification ABS BS Inch page 15/ 19 Schaffhausen, January 2015

- System Specification - • Type 2282 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. Georg Fischer Piping Systems guided float switches are available in PP and PVDF to provide best chemical compatibility to corrosive liquids. • Type 2284 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. Georg Fischer 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. • Type 2285 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. Georg Fischer 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. 8.1.4 pH Sensors All pH sensors from Georg Fischer Piping Systems Signet are constructed as combination electrodes. One electrode is comprised of a pH sensitive glass stem. The other electrode uses a silver / silver chloride reference electrode. Both electrodes are contained within a common housing. 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 value of the fluid. The reference cell is used to provide a stable reference signal. The pH signal is measured against a 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 to the Georg Fischer Piping Systems Signet Transmitter unit. All sensors are equipped with integrated temperature compensation. 8.1.5 ORP Sensors System Specification ABS BS Inch page 16/ 19 Schaffhausen, January 2015

- System Specification - All ORP sensors from Georg Fischer Piping Systems Signet are constructed as combination electrodes. One electrode is comprised of a noble metal such as platinum or gold. The other electrode is a silver/silver chloride reference electrode. Both electrodes are contained within a common housing. Temperature compensation is not used in ORP measurements. 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 conditioned and sent as a blind 4-20 mA or as a digital S3L signal to the Georg Fischer Piping Systems Signet transmitter unit. 8.1.6 Conductivity Sensors All Conductivity sensors from Georg Fischer Piping Systems Signet 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 half cells 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 Georg Fischer Piping Systems Signet Transmitter unit. 8.2 Multi Parameter Instruments 8.2.1 Transmitters The Georg Fischer Piping Systems Signet 9900 Transmitter provides a single channel interface for many different parameters including Flow, pH/ORP, Conductivity/Resistivity, Salinity, Pressure, Temperature, Level, Dissolved Oxygen and other sensors that output a 4-20 mA signal. The display shows separate lines for units, main and secondary measurements as well as a dial-type digital bar graph. The 9900 is offered in both panel or field mount versions. Both configurations can run System Specification ABS BS Inch page 17/ 19 Schaffhausen, January 2015

Designed for complete flexibility, plug-in modules allow the unit to easily adapt to meet changing customer needs. Optional modules include Relay, Direct Conductivity/ Resistivity, H COMM and a PC COMM configuration tool. • 1 sensor input (Flow, pH/ORP, Conductivity/Resistivity, Salinity, Pressure, Temperature, Level, Dissolved Oxygen and other sensors that output a 4-20 mA signal, Signet 8058 i-GoTM Signal Converter required) • 1 analogue output (4-20 mA), 2nd optional analogue output is available • 1 Open Collector output • Optional relay module with 2 Dry Contact Relay SPDT • Power supply 12-32 VDC 8.2.2 Batch Controller The batch controller manufactured by Georg Fischer Piping Systems Signet Type 9900 is based on the Transmitter. It allows 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 Signet 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. 8.2.3 Multi-Parameter Controller The Georg Fischer Piping Systems Signet 8900 Multi-Parameter Controller takes the concept of modularity. Each 8900 is field commissioned with the users specified combination of inputs, outputs, and relays using simple-to-install modular boards into the base unit. Configure the system by selecting either two, four, or six input channels which accepts any of the Signet sensors listed below, and/or other manufacturer's sensors via a 4-20 mA signal converter (Signet Model 8058). To complete your unit, choose a power module with universal AC line voltage or 12 to 24 VDC. Analogue output and relay modules are available and easily installed. Derived measurements include difference, sum, ratio, percent recovery, percent rejection, percent passage and BTU.
