Diehl Metering SHARKY 775 Guide D'installation page 21

English
The meter can be installed in both horizontal and vertical pipe
sections, provided air bubbles cannot collect in the meter.
The flow sensor must always be filled with liquid.
Avoid frost at the meter.
ƒ
We recommend installing the flow sensor in a tilted position.
ƒ
The minimum system pressure must be 1 bar to avoid cavitation.
ƒ
Make sure the meter is installed sufficiently far away from possible
sources of electromagnetic interference (switches, electric motors,
fluorescent lamps etc.).
ƒ
If possible install the cables of the flow sensor or temperature sensor
freely suspended (not bundled - antennae effect) with sufficient dis-
tance to electromagnetic disturbance.
