The difference between rotary vane water meter and screw wing water meter
Level Woltman meter: the level of Woltman water meter for the total flow measurement of large flow pipe. It is particularly useful for water supply pipeline and large factory mining content. The main characteristics of large flow capacity, small volume, compact structure, convenient operation and maintenance.
Rotor type water meter rotor type water meter is suitable for small diameter pipeline unidirectional flow measurement. Such as total household water metering caliber 15mm, 20mm specifications of pipe. The water meter is mainly composed of a casing, impeller measuring mechanism and a retarding mechanism, as well as indicator, has the advantages of simple structure characteristics.
