High Accuracy Vertical Woltman Water Meter
The vertical spiral wing water meter is a kind of spiral wing water meter. The spiral wing water meter, also known as the Woltmann water meter, is a kind of speed water meter. It is suitable for use in large-diameter pipelines. It is characterized by large flow capacity and small pressure loss.
Product Features:
1.No worm gear transmission mechanism, the impeller direct drive counter, transmission efficiency, and low initial flow.2. Wide range, suitable for large changes in traffic occasions.
3. Full flow detection, high precision measurement.
4. Dry magnetic structure, to ensure that the counter is clean, and clear display.
5. Six-digit increase in digital character wheel display readings, reading more clearly.
6. Removable measuring movement structure, easy maintenance.
7. Internal adjustable structure, to prevent unauthorized regulation.
8. Built-in stainless steel filter, the effective protection of measuring institutions.
9. High wear-resistant bearing system (gemstone bearing + high wear-resistant carbide shaft) ensures long-term product stability and reliability, significantly increasing product maximum flow.
10. Use stainless steel fasteners and epoxy resin powder to spray inside and outside the shell, to maximize antirust and extend product life.
11. Optional tamper protection cover. (To prevent users from unauthorized movement, damage, or changing the measurement structure, the maximum play anti-theft effect).
Working conditions:
