The mean outer diameter (dem) is the average value which results from the
measurements of the outer diameter at an interval of d n and 0.1 dn to the end of the
test piece. It is determined by measuring the circumference to 0.1 mm accuracy with
a measuring tape.
The mimimum and maximum wall thickness is determined to 0.1 mm, whereby the
measurement points should be distributed on the pipe circumference as evenly as
possible. All measured values must be within the allowable tolerance limit.
Ovality is the difference between the measured maximum and the measured
minimum external diameter (de) at the same cross-section. It is calculated to 0.1 mm
and measured immediately after production. The ovality requirement applies to the
timepoint of manufacture.

6.5 Pressure Regulating Valves
All pressure regulating valves as supplied by Georg Fischer Piping Systems shall
have the following characteristics:
Pressure ranges for all pressure regulating valves are the following:
 DN10–50
from 0 up to max. 10 bar
 DN65–80
from 0 up to max. 6 bar
 DN100
from 0 up to max. 4 bar
6.5.1 Pressure Reducing Valves
As supplied by Georg Fischer 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. Following types
and sizes are available:
 Type 582, compact Pressure Reducing Valve, sizes DN10–50
Features:
 Metal free central housing union nut


Set pressure selectable 0 - 9 bar or 0.3 – 3 bar

Manometer optional

Manometer assembly possible on both sides



Possibility to show either inlet or outlet pressure

Injection molded directional arrow for direction of flow


Type V82, Pressure Reducing Valve with an integrated manometer, sizes
DN65-100
6.5.2 Pressure Retaining Valves
As supplied by Georg Fischer Piping Systems serves to keep the working or system
related pressures constant, to balance out pressure pulsation, and to reduce
pressure peaks in chemical process systems. If the inlet pressure rises above the set
value, the pressurized valve piston is lifted against the spring force. Consequently,
the valve opens and there is a reduction of pressure through the outlet pipe. The
valve closes as soon as the inlet pressure sinks below the pre-set spring tension.

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 p pf 0.5 bar is mandatory with servo-assisted valves.
 Type, 165, sizes DN10-50

plastic coated stainless steel spring with minimal opening pressure (10-80 mbar).
Optionally Nimonic / Nimonic-ECTFE can be used.
7. Welding and assembly
All butt fusion fittings and valves shall also be manufactured with laying lengths
designed for use with fusion machines IR-63 Plus, IR-110 Plus, IR-225 Plus and IR315 Plus from Georg Fischer Piping Systems, providing welds with increased
mechanical and chemical stability than conventional welding methods (socket- and
butt fusion).
The IR Plus fusion machines use 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 Georg Fischer 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 ends from sticking to the heater plate.
Socket fittings require the use of Socket Fusion welding tools according to DVS
2007-15, with heating bushes System B.
The BCF fusion technology joins SYGEF Standard (PVDF) piping components of
dimensions d20-110 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 Georg Fischer Piping Systems are allowed to perform
fusion on the BCF Plus machines manufactured by Georg Fischer Piping Systems.
The welding and the installation should be in accordance with Georg Fischer Piping
Systems Guide to the Installation and Use of Plastic Pipeline.

8.1 Sensors
The sensors listed hereafter will transfer the measured value to a Georg Fischer
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 (Georg Fischer Piping Systems Signet serial signal).
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
PVDF, Wafer fitting in sizes d75–315 and weld-o-let in sizes d75–400 supplied by
Georg Fischer 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 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).
Systemspecification SYGEF Standard (PVDF)
Schaffhausen, Januar 2016
Seite 16/ 22
GF Piping Systems
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 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 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 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 Ultrasonic Flowmeter
The U3000/4000, the PF220/330 and the U1000 from Georg Fischer Piping system
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.
8.1.2.3 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.

GF Piping Systems
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, DN10–65
 Type 335, DN25–65
 Type 350, DN25–65
8.1.2.4 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
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 Georg
Fischer Piping Systems SIGNET is offered as a blind frequency, 4-20 mA or digital
S3L output, or with integral display and control relays.
8.1.3 Level Sensors and Level Switches
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 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 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 / 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 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 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 ultrasonic level sensors
are compatible with GF transmitters, indicators, controllers and valve actuators.

8.1.3.3 Point Level Switches (Series 2280)
The GF 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 vibration
forks are equipped with digital PNP/NPN or relay output. Versions with ATEX or
WHG approval are available.
The 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 conductive multipoint switches work
with liquids of min. 10µS conductivity. Their four-in-one design allow fast installation
and provide 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 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 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 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
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 Georg
Fischer Piping Systems SIGNET Transmitter unit.

Schaffhausen, Januar 2016
Seite 19/ 22
GF Piping Systems
8.1.5 ORP Sensors
All ORP sensors from Georg Fischer 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 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 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 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 9900 is offered
in both panel or field mount versions. Both configurations can run on 12 to 32 VDC
power (24 VDC nominal). The 9900 can also be loop powered with compatible
sensors.
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 and other sensors that output a 4-20 mA signal, Signet
8058 i-Go™ Signal Converter required)
 1 analogue output (4-20 mA)
 1 Open Collector output
 Optional relay module with 2 Dry Contact Relay SPDT
 Power supply 12-32 VDC
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. Analog output and relay modules are available and easily installed. Derived
measurements include difference, sum, ratio, percent recovery, percent rejection,
percent passage and BTU. The menu system can be programmed to display in multilanguages 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
8.3 Batch Control
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.
