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
