Installation Manual
Domo M
Optical sensor kit with M-Bus output
Description
The Domo M optical sensor is designed for usage with Sensus
DomoJet and DomoMUK water meters.
The device detects the revolutions of the litre pointer. The reading
is then sent to a standard M-Bus system.
During operation, the module is supplied with power by the M-Bus
network. A built-in battery provides power supply when the meter
is temporarily not connected to the M-Bus network.
The sensor is also suitable for usage with the meters of the Modularis
series. Please check for compatibility with your meter.

mandatory requirements of the following directives and standards:
– Directive 2014/30/EU (EMV – Electromagnetic Compatibility)
