Product Description
Honeywell Home EW370 Series Woltman flow meters are used for volume measurement of heating or chilled water in hydronic heating and cooling systems.
They have a mechanical roller counter with fixed pulse output for connection to an energy calculator, e.g. Honeywell Home EW500 Series, or remote readout applications. When combined with an EW500 energy calculator they act as flow sensor and provide volume measurement to the energy calculator. When combined with an EW535M0056 pulse to M-Bus converter they can be integrated into an M-Bus network.
