Bulk Vertical Water Meter
Vertical spiral wing water meter is a spiral wing water meter, screw-type water meter, also known as the Worman (Woltmann) water meter, is a speed meter, suitable for use in large diameter pipelines, which is characterized by large circulation capacity, the pressure loss is small. Like a rotor-type water meter, a screw-type water meter is also a type of a speed meter. When the water flow into the water meter, the direction of the impact of the axis of the water droplets spiral wing after the rotation, the impeller speed and flow rate is proportional to the gear after the gear, the indicator device shows the total water through the water meter. The spiral wing type water meter is divided into two categories: horizontal spiral wing type water meter and vertical screw type water meter. Most of the industrial meters adopted are horizontal spiral wings.
1. No worm gear transmission mechanism, the impeller direct drive counter, transmission efficiency, 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 clean, 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. Using 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 change the measurement structure, the maximum play anti-theft effect).
|DN||Flow range||Q4||Q3||Q2||Q1||Min reading||Max reading|
1. Temperature:cold water T30,hot water T30/T9;
