Use The impeller type cold and hot water meter is compact in design and used to correctly acquire physical cold or hot water consumption. The meter consists of a flow element and a totalizer. Functions The compact, mechanical impeller water meter is used on drinking water (cold or hot) and consists of a flow element and a totalizer with display. The flow measuring section is made of brass and includes a sieve at the input to collect larger dirt particles. The water flows through the flow measuring section to drive the single-jet impeller. The flow value is transmitted using a magnetic...

Device sealing After mounting the meter, seal all components to prevent tampering (observe national regulations): ● Flow measuring section with fitting (inlet) ● Add-on module with adhesive seal Add-on modules An external add-on module (WFZ31 or WFZ661) can be attached to any series WFx30.. meters. To do this, proceed as follows: 1. Remove cover from the water meter 2. Attach the add-on module and adhesive seal The modules do not affect acquisition of consumption data and can therefore be retrofitted at any time. Maintenance Install only calibrated water meters. Comply with all national...
