Woltman Type Irrigation &Agriculture Water Meter works, design structure, the maximum permissible error and conditions of use

Spiral wing type water meter, water meter is also called volts, a velocity meter, suitable for use in large diameter pipeline, which is characterized by large flow capacity, small pressure loss.

Woltman Type Irrigation &Agriculture Water Meter

As the rotor type water meter, a spiral wing type water meter belonging to the velocity meter. When the water flows into the water after the impact, along the axial direction meter spiral wing shaped impeller outflow, impeller rotational speed and flow speed is proportional to, through the reduction gear transmission, the indicator displays the total amount of water meter.

Woltman Type Irrigation &Agriculture Water Meter is divided into horizontal spiral wing type water meter and the vertical spiral wing type water meter two categories. Most of the industrial scale is horizontal spiral wing type water meter. In addition the detachable horizontal spiral wing type water meter, flow meter, because of its wide range of strong versatility, installation and repair in the surface case is not cut off the water supply is not removed, has also become a series of products, users are welcome.

Characteristic.

Wet type E: with high precision measurement, small starting flow, reading is convenient; the liquid seal type F: counting mechanism adopts a special liquid packaging, good antifouling performance, can keep clear reading; cold, hot water optionally; series of versatility; large flow capacity, small pressure loss; flow capacity; compact structure.

Main technical parameters:

Water meter imported German technology, detachable structure, water does not need to be disassembled from the pipes, movement can be pulled out for repair or replacement; copper sealing counter readings, permanent remain legible, universal measuring mechanism, reduce the spare parts; magnetic connection, the transmission resistance is small, reliable operation, small pressure loss, long service life. Woltman Type Bulk Water Meter is unchanged in the original metering mechanism, counter with multiple output distance function, appearance more beautiful. The F table is a recently developed wet seal liquid water gauge, the detachable structure. Counter with special liquid encapsulation and can keep the liquid does not leak, to ensure that the counting mechanism is not contaminated, and has the advantages of high precision, small starting flow counting, antifouling, reading convenience etc..

Use:

Level Woltman water meter for measuring flowing through the water pipe cold (hot) the total amount of water.

Conditions of use:

Temperature class: T30

Pressure rating: MAP10

Pressure loss grade: P63

The upstream flow sensitivity level: U10

Flow sensitivity level: D5

The maximum permissible error:

A) low area (Q1 ≤ Q < Q2) maximum permissible error of ± 5%

B) high (Q2 ≤ Q ≤ Q4) maximum permissible error of ± 2%
