The pulse adapter acquires and handles the pulses received from one or two
consumption meters and transmits the data to the central radio readout unit.
The pulse adapter is a component of the Radio Metering System.
It is used where consumption meters with pulse output are installed, whose data are to be
transmitted to the central radio readout unit OZW20. Such meters may be meters for hot
or cold water, gas, electricity, etc.
For the field of use of the Radio Metering System, please refer to data sheet N2860E.
– Acquisition of pulses delivered by the connected consumption meters
– Monitoring of pulse line with Namur circuit
– Handling of pulses and storage of consumption data
– Storage of consumption data on the set day
– Random transmission of data via radio six times per day
When ordering, please give type reference AEW22.2.
The pulse adapter is a component of the Radio Metering System and is designed for
