Water meters using the multi-jet principle are the best cost/performance, long life, flow measurement instruments.
Wide clearances in the measuring chamber and negligible area of contact between static and moving parts are the key reasons for the high reliability of this design even in hard water.
The only moving part, the impeller, is in contact with the water for minimum wear and highest reliability
Magnetically driven sealed registers
Stainless steel/glass encapsulated option is unconditionally guaranteed against fogging
