The water meters comply with the requirements of: PN-ISO 7858 Cold Water Meters: "Compound Water Meters"
Advantages:
- the change-over valve automaticaly guides the water flow to the main or lateral meter depending on the flow volume,
- meassuring ranges interface with one another,
- the meassuring range is wide - from the minimum volume flow on the lateral meter to the maximum volume flow on the main meter,
- option MK with need relays incorporated in the counter housing for remote data transmissions. ZZO-4, ZZO-5, MLR 2.1, IZM 972 - an accessories for remote volume totalizing is available on
request,
- option NKP equipped to fitting puls transmiter.
Special Features:
- a compound water meter consists of: the main water meter of MWN propeller type, dry, with a horizontal impeller axie and removable meassuring insert,
- a lateral water meter of Js vane-wheel single-jet or WS wane-wheel multi-jet type,
- a change-over spring valve that does not require an external power supply for operation,
