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%

Use AMR Remote Reading Brass Cold Water Meter, the principle outlined, characteristics, conditions of use and the main purpose

Summary.

Anti flip type water meter is one of the new product of our factory. Only with the latest design. Structural change of water movement, regardless of direction and indicated the same or opposite direction of water meter, water meter can work properly, can eliminate the water meter reverse installation is stealing water behavior.

AMR Remote Reading Brass Cold Water Meter

Characteristic.

AMR Remote Reading Brass Cold Water Meter and the same as ordinary water meter.

The reverse installation of water meter readings to increase, and the error is +3~+20%.

Careful design, advanced structure, convenient installation and repair.

The meter type C table using the pointer type display, E table using a pointer wheel combined display, has clear reading convenience features, small starting flow etc..

The use of prepayment technique, using encryption special treatment guarantee card, table will not be attacked in the water meter and the external data transfer.

The use of large scale special micro processing integrated circuit, high reliability design and manufacturing method, damp proof, moisture-proof, anti jamming, anti attack.

With the purchase of function, can be preset “restriction” to prevent the user from hoarding water.

Water shortage alarm can be preset amount, close the valve alarm water is insufficient, the card can be re open the valve, the water balance is zero shut down, the user to buy water back card to open the valve.

Control valve used to control and manufacturing technology of special, both by water automatic valve maintenance, improves the reliability of long-term use.

With abnormal detection function, automatically close the valve when the magnetic attack or flow sampling signal is cut off.

With the Single Jet Dry Dial Brass AMR Remote Reading Water Meter, large capacity lithium battery prepared table, water table used for a long time; in case of special circumstances, the battery is about to run out of time, the valve will automatically shut down and alarm.
