Installation and electrical connection
Before delivery the flow sensor was tested in the factory and is ready to use as soon as it has
been fitted and the electrical leads connected. Safe access to the integral measuring unit for
visual inspection should be provided at all times, even if the unit is in operation.
CAUTION! Material damage!
Hold the volume sensor during fitting and in transport only by its housing, never by the
plugged connector socket!
Before installing, check that
the wetted materials of the device are suitable for the media being used (
the equipment is switched off and is in a safe and de-energised state.
the equipment is depressurised and has cooled down.
SUITABLE TOOLS:
Use only suitable tools of the correct size.

Installation VZ...AL
The device can be connected with your system with the aid of pipe connections in the housing
(
CAUTION! Material damage!
Only piping and connectors may be used which are suitable for the expected pressure
range. Observe the specifications of the manufacturer concerned!
Ensure that the maximum operating pressure of the flow sensor cannot be exceeded.
Mounting:
Firstly deaerate the system completely.
Clean the flow system thoroughly. All component parts must be free of installation resi-
dues (metal shavings, weld spatter).
Connect the pipes to the inlet and outlet of the metering unit. Observing the manufactur-
er’s instructions.
Here is:
the fitting position: any
the flow direction: any
When installing, make sure no jointing compounds get into the interior of the pipelines.
IMPORTANT!
The flow sensor must not be distorted during installation.
After commissioning, check all connections for leaks.
