2 Safety instructions
• The device described is a subcomponent for integration into a system.
- The manufacturer is responsible for the safety of the system.
- The system manufacturer undertakes to perform a risk assessment and to
create a documentation in accordance with legal and normative requirements
to be provided to the operator and user of the system. This documentation
must contain all necessary information and safety instructions for the operator,
the user and, if applicable, for any service personnel authorised by the manufacturer of the system.
• Read this document before setting up the product and keep it during the entire
service life.
• The product must be suitable for the corresponding applications and environmental conditions without any restrictions.
• Only use the product for its intended purpose (→ Functions and features).
• Only use the product for permissible media (→ Technical data).
• If the operating instructions or the technical data are not adhered to, personal
injury and/or damage to property may occur.
• The manufacturer assumes no liability or warranty for any consequences
caused by tampering with the product or incorrect use by the operator.
• Installation, electrical connection, set-up, operation and maintenance of the unit
must be carried out by qualified personnel authorised by the machine operator.
• Protect units and cables against damage.

CAUTION
For medium temperatures above 50 °C (122 °F) some parts of the housing can
heat up to over 65 °C (149 °F). Risk of burns.
► In this case do not touch the unit.
► Protect the housing against contact with flammable substances and uninten-
tional contact.
► Do not press the pushbuttons manually; instead use another object (e.g.
ballpoint pen).
3 Functions and features
The unit monitors water-based fluids (water, deionized water, cooling water).
It detects the two process categories volumetric flow rate and medium tempera-
ture.
Pressure Equipment Directive (PED):
The units comply with the Pressure Equipment Directive and are designed
and manufactured for group 2 fluids in accordance with the sound engineering practice.
4 Function
• The unit detects the volumetric flow rate based on the Vortex measuring
principle.
• The unit displays the current flow and temperature. It generates 2 output
signals according to the parameter setting:
OUT1: 2 selection options
- switching signal for volumetric flow rate limit value
- frequency signal for volumetric flow rate
OUT2: 4 selection options
- switching signal for volumetric flow rate limit value
- switching signal for temperature limit value
- frequency signal for volumetric flow rate
- frequency signal for temperature

4.1 Switching output
OUTx changes its switching status if it is above or below the set switching limits
(flow or temperature). Hysteresis or window function can be selected. Example of
volumetric flow monitoring:
Hysteresis function Window function
SP
rP
SP = set point
rP = reset point
HY = hysteresis
Hno = hysteresis NO (normally open)
Hnc = hysteresis NC (normally closed)
When the hysteresis function is set, the set point [SPx] is defined first and
FH
FL
SP = upper limit
rP = lower limit
FE = window
Fno = window NO (normally open)
Fnc = window NC (normally closed)
then the reset point [rPx] which must have a lower value. If only the set
point is changed, the reset point remains constant.
When set to the window function, the upper limit [SPx] and the lower limit
[rPx] have a fixed hysteresis of 0.25 % of the final value of the measuring
range. This keeps the switching status of the output stable if the flow rate
varies slightly.

4.2 Frequency output
The unit provides a frequency signal that is proportional to the volumetric flow
quantity and the medium temperature.
Up to the limit value set under [FEPx] (for OUT2 = TEMP: between the limit values
set under [FSP2] and [FEP2]) the frequency signal is between 0 Hz and the fre-
x
quency value set under [FrP

5 Installation
► Flow in the direction of the arrow. Observe the installation direction.

► Make sure that pipe and sensor have the same internal diameter.
► Avoid deposits, accumulated gas and air in the pipe system. Install the unit so
that the measuring pipe is always completely filled with medium.
► Install in front of or in a rising pipe.
► Recommended tightening torque: 30 Nm
► Avoid disturbances on the inlet and outlet side. To do so, provide for the
following inlet and outlet pipe lengths:
