ELECTRONIC ACCESSORY | TRANSMITTER Generation of a high pulse frequency, mainly for electronic processing (e.g. by signal converter or PC), remote transmission of analogue flow rate values to display or evaluation units, pipe leakage monitoring, control of pumps, valves ► Sensor easily replaced without adversely affecting the water meter ► High pulse resolution

ELECTRONIC ACCESSORY | TRANSMITTER The sensor acts together with a reflex impeller built into the counter as standard to provide a high-resolution pulse frequency proportional to the flow rate. • 3-wire version (Open Drain) Infrared reflex pulse transmitter (Opto N / Opto OP) Operating temperature Storage temperature Protection class Cable length Electromagnetic compatibility TECHNICAL DATA Forward-, backward detection mA Signal output NAMUR * With 150 Q resistance and inverse polarity protection OPTO VR N OPTO OD OPTO VR OD OPTO VR OD S For bulk water meter Model range Open Drain* Open Drain*...
