Diehl Hydrus - Non-Return Valve Installation; Communication Interfaces; Optical Interface Configuration; Encoder Protocol Details

Finishing tasks

Slowly open the shuto valves upstream and downstream of the
HYDRUS.

Check for possible leaks at the connections.
The HYDRUS must always be completely lled with water.
Failure to use provided ber gaskets or equivelant may result in
connection leaks and damage to the HYDRUS.
6.2 Non-return valve
If desired, the HYDRUS can be delivered with a non-return valve (accessory).
This valve must be installed in the discharge of the HYDRUS.

7. Communication
The HYDRUS has dierent communication interfaces:

Optical

Encoder
7.1 Optical interface
The HYDRUS can be congured by using the integrated optical interface.
IZAR@MOBILE2 software is used to read data and set parameters. This
software can be found at https://www2.diehl.com/metering/en/diehl-
metering/support-center/downloads.
If an error occurs during conguration, conguration must be started
again using the optical interface.
For correct conguration, place the opto head on the optical interface of
the HYDRUS.
We recommend the Bluetooth Opto Head IZAR OH BT for conguration.
