Application
The device is a calorimetric ow monitor for monitoring of ows in liquids in all elds of industry.
Application examples:
• Monitoring cooling water circulation systems of pumps, turbines, compressors and heat
exchangers
• Monitoring pump functionality
• Leak monitoring in process lines
• Monitoring lubrication systems
• Filter monitoring in the beverage industry
Function
The device is mounted in the wall of the pipe.
The sensor tube is the junction point with the applied medium and is in direct contact with it. Inside,
the sensor is installed, that is used for the detection of the ow and for its conversion into an electrical
signal.
The device measures the ow of a liquid medium with the calorimetric measurement method. The
calorimetric measuring principle is based on cooling a heated temperature sensor. Heat is removed
from the sensor by forced convection due to medium owing by. The extent of this heat transfer
depends on the medium velocity and the difference in temperature between the sensor and medium.
The higher the ow velocity of the medium, the greater the temperature sensor cooling. For the
detection of temperature difference the temperature of the non-heated medium is additionally
detected by a second temperature sensor.
The temperature difference represents the measuring value, which is monitored by a switch output for
exceedance of a limit value.
The measuring value is diagrammed at the LED bar graph.
By 2 sensor keys and the ten-digit LED bargraph the adjustment to the application specic conditions
and the settings for the switch output can be carried out.

Safety notes
Each person that is engaged with inauguration and operation of this device, must have read and
understood this technical manual and especially the safety notes.
Installation, electrical connection, inauguration and operation of the device must be made by a
qualied employee according to the informations in this technical manual and the relevant standards
and rules.
The device may only be used within the permitted operation limits that are listed in this technical
manual.
Every use besides these limits as agreed can lead to serious dangers.
The materials of the device must be chosen resp. checked for compatibility with the respective
application requirements (contacting materials, process temperature). An unsuitable material can lead
to damage, abnormal behavior or destruction of the device and to the resulting dangers.
The sensors may not be used as sole device for prevention of dangerous conditions in machines and
plants.
This measuring device meets article 3 (3) of the EC directive 97/23/EC (pressure equipment device
directive) and is designed and produced in good engineer practice.
The device meets the legal requirements of all relevant EC directives.
Using the device in a manner that does not fall within the scope of its intended use, disregarding
this instruction, using under-qualied personnel, or making unauthorized alterations releases the
manufacturer from liability for any resulting damage. This renders the manufacturer‘s warranty null
and void.

Installation
The correct function of the device within the specic technical data can only be guaranteed, if the
permitted process and environmental conditions (see chapter „Technical data“) will not be exceeded.
Process and environmental temperature
At high process temperatures a heat transfer to the terminal housing can be reduced by isolation of
the medium carrying part of the plant.
Installation notes
Drive the system pressure free prior installation resp. deinstallation of the sensor.
Be also sure that no medium is owing in the system. At extreme system or medium temperatures
there could exist serious dangers.
The screw-in of the thread process connection by using the terminal housing, the connection plug
resp. the connection cable is not permitted.
The tightening of the thread process connection may only be done at the hexagon by a suitable
spanner and with the maximum permitted torque strength.
The maximum permitted torque strength is 50 Nm.
The housing can be rotated every time, also at operation, mechanically by 330°.
Installation place
The choice of the place of installation of the sensor and the length of the sensor tube are of
considerable importance for the quality and the reliability of the measuring results.
The sensor tip should be completely surrounded by medium.
Position the sensor tip in the area of maximum uid velocity (pipe center).
The minimum sensor immersion length is L ≥16 mm.

Recommended orientation
• Lateral installation for horizontal pipes.
• Installation in the ascending pipeline for vertical pipes.
In hygienic applications installation with minimum 3° inclination, because of self-draining.
Conditionally recommended orientation
• Installation from below for horizontal pipes only if the pipe is free of deposits.
• Installation from above for horizontal pipes only if the pipe is completely lled with medium.

ACS-CONTROL-SYSTEM GmbH l Lauterbachstr. 57 l D-84307 Eggenfelden l www.acs-controlsystem.de l [email protected]
8
Inapplicable orientation
• Do not install in down pipes open towards the end.
• The sensor tip should never touch the pipe wall.
Disturbance inuence in the pipe system
The sensor requires a fully developed ow prole for correct monitoring.
For this reason, steadying sections must be provided in the pipe after a pump, pipe bend, internal
ttings and cross-sectional changes.
Ø >> Pipe diameter
S >> Disturbance inuence

Electrical connection
The electrical connection of the device must be carried out according to the respective country specic
standards.
Incorrect installation or adjustment could cause applicationally conditioned risks.
For inauguration it is suggested to switch off all connected control devices to avoid unintended control
actions.
Potential equalization - earthing
The device must be grounded.
The earthing can be carried out by the metallic process connection.
The metallic parts of the device are electrically connected with the socket of the plug M12.
Connection cable
For the connection only suitable cables may be used, that fullls the requirements e.g. regarding
temperature, chemical resistance or laying at the place of installation.
Use only shielded signal and measurement wires and install these wires separated from power leading
wires.
Connect the cable shield of a connected cable only at one side to earth, ideally at the installation place
of the device.
Supply voltage
The voltage applied to the terminal contacts may not exceed the maximum permitted supply voltage
to avoid damage of the electronic.
The maximum permitted supply voltage range is:
Version type GA 16…45VDC
Version type WB 20…253VAC/DC
All connections are reverse polarity protected.
A fuse is integrated internally at the power supply circuit. Due to this the installation of a ne
protection is not necessary.
The switch output is not protected by this fuse.

Switch output
Version type GA - PNP switch output
An inductive loads at the pnp switch output, e.g. relays or contactors may only be used with a free-
wheeling diode or a RC protection circuit to avoid high voltage peaks.
The load at the PNP switch output will be connected to the terminal +L of the supply voltage by a
semiconductor switch contactless and by this bounce-free.
At an activated switching state a positive signal near supply voltage is feed to the output.
At deactivated switching state and at failure of supply voltage the semiconductor switch is shut off.
The PNP switch output is current limited to 0,5 A and is overload and short circuit protected.
The device is suitable for non-coincidence use. Using both outputs the NO and NC outputs leads
contrary states at trouble-free operation.
In the case of failure or at wire break both electronic switches are opened.
By using a two-channel evaluation, besides the ow monitoring also a function dependent monitoring
of the sensor can be realized.
Version type WB - relay output
Inductive loads at the relay contacts, e.g. auxiliary contactors or magnetic vents may only be used
with a free-wheeling diode or a RC protection circuit to avoid high voltage peaks.
The load at the relay output will be connected to the terminal L/+L of the supply voltage.
At an activated switching state the supply voltage of the connection terminal L/+L is feed to the
output.
At deactivated switching state the output is voltage and potential-free.
The device is suitable for non-coincidence use. Using both outputs the NO and NC outputs leads
contrary states at trouble-free operation.
In the case of failure or at wire break the terminal NO is potential-free and the terminal NC is
connected to the terminal L/+L.
By using a two-channel evaluation, besides the ow monitoring also a function dependent monitoring
of the sensor can be realized.
