Installation – Recommendations
Continuous contact
The Reed switch emits pulses of varying length depending on the water meter flow rate. Continuous contact can also occur when the roller counter is standing still. Connected devices must be able to withstand continuous contact or protective measures must be provided (wiping contact).
Long cable distances
For cable distances greater than 100 m without signal amplifier, we recommend the use of shielded and twisted cables.
See cable recommendations for electricians - BAe20603
Pulse transmission interference
In case of interference during the pulse transmission between the pulse generator and the pulse receiver, (i.e. cable is in the same duct as power cable), we recommend shielded and twisted cables.
