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.

8.1.3.1 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.

• 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
Page17
- 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.

8.2.2 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. The menu system can be programmed to display in multi-
languages including English, German, French, Spanish, Italian, and Portuguese.
