Woltman water meter

Woltman Helix water meter can be divided into horizontal Helix Woltman water meter(WPH) and vertical Helix Woltman water meter(WS) according to different of water meter internal structure, but the water meters are installed horizontally,The advantage of vertical Woltman water meter(WS) is a wider flow range(R80/R160/R200). The installation does not need the strict requirements of straight pipe section and external filter.

Product Description

Characteristics of woltman water meter

Wide measuring range.

Full flow detection, high measurement accuracy.

Dry magnetic transmission structure ensures the counter is clean and clear.

The six digit enlarged digital wheel displays the reading,the reading is clearer.

The detachable metering structure is convenient for maintenance.

Stainless steel filter screen effectively protects the measuring mechanism.

The high wear-resistant bearing system (bearing for aviation instrument + high wear-resistant cemented carbide shaft) ensures the long-term stability.

Stainless steel fasteners and epoxy resin powder are applied inside and outside the shell to maximize rust prevention and prolong the service life.

Optional anti prying protective cover

 Low starting flow, high overload capability
