Impeller multi jet water meter with pulse emitter for remote reading of cold water brass DN20
The impeller type multi jet water are designed for cold water / hot water measurement. It's made of brass. It can work for situations where a wide flow range must be covered. All moval parts have an optimised specified weight. Quick responsiveness, even at low flow rates, combined with power reserves for high flow rates.
