7. Solvent Cement & Cleaner
For adhesive jointings, ABS cement with gap-filling adhesives must be used for
solvent cementing. GF Piping System recommends the Henkel cement system
TANGIT ABS for all ABS solvent cement joints. All specifications are based on using
TANGIT ABS, including strength and chemical resistance.
ABS TANGIT contains app. 20% ABS, dissolved in a blend of solvents. The solvents
soften and macerate the edges of the surfaces they are applied to. Once the solvents
have evaporated, they leave a homogenous joint with the same mechanical, thermo
and chemical properties as of the ABS pipe system.
The jointing surfaces of pipe and fitting must be clean and free of grease. They must
be cleaned with TANGIT cleaner.
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

8.1 Sensors
The sensors listed hereafter will transfer the measured value to a GF Piping Systems
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 (4-20mA, open collector or sinusoidal voltage) or a digital signal called S3L
(GF Piping Systems Signet serial signal).

8.1.1 Installation Fittings
Installation fittings consist of a body out of PP-H or PVC-U with connection elements
PE. 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 d75–315mm and weld-o-let made out of
PE100 in sizes d75–630mm supplied by GF Piping Systems. Sensor thread
connection shall be 1¼" NPSM.
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 GF 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 GF 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 liter 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 GF
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 GF Piping
Systems SIGNET. 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 GF 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
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, DN10–65mm
• Type 335, DN25–65mm
• Type 350, DN25–65mm
8.1.2.3 Magmeter
The Magmeter sensor from GF Piping Systems SIGNET 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 sensor is inserted into. The Magmeter of GF Piping Systems
SIGNET 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
The U3000/4000 and PF220/330 from GF Piping system 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, the Ultraflow 3000/4000 for fixed
installation and the 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.
8.2 Level Sensor and Level Switches
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 GF Piping Systems SINGET 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 GF 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 GF Piping Systems
SIGNET Transmitter unit.
8.2.2 Ultrasonic Level
8.2.2.1 Ultrasonic Level Sensors (Series 2260 / 2270)
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
compatible with GF Piping Systems transmitters, indicators, controllers and valve
actuators.
8.3 Radar
8.3.1 Radar 2290
The 25 GHz (K-band) 2290 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 of type 2290 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 2291
With its ability to read accurately when other non-contacting or invasive methods fail,
the guided level transmitter type 2291 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, the type 2291 can be
installed in tanks with limited space. The type 2291 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 Switches (Series 2280)
The GF 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. GF
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. 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.
• 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. GF 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. 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.
• 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. 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 from GF Piping Systems SIGNET 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 to the GF Piping Systems
SIGNET Transmitter unit.
8.5.2 ORP Sensors
All ORP sensors from GF Piping Systems SIGNET 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 the GF Piping Systems SIGNET Transmitter unit.
8.5.3 Conductivity Sensors
All Conductivity sensors from GF 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 4-20mA or as a
digital S3L signal to the GF Piping Systems SIGNET Transmitter unit.

8.7 Batch Control
The batch controller manufactured by GF Piping Systems Signet Type 5600 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.
