MH-magW803E electromagnetic water meter is our company specifically for the water supply industry design, meet the city water supply measurement standards,it suits the regional metering and large user metering of water supply pipe network,it’s beneficial to water supply enterprises to improve the recovery rate of water supply,reduce the loss, and reduce the level of water without income. It’s the best choice for metering upgrade of water supply enterprises.

Adopting the unique design of all stainless housing, handheld infrared remote control operation, IP68 seal protection design，it can be used in the underground and other wet occasions. Conventional lithium battery pack is used as its power supply, without external power supply.

The sensor part adopts all-pass structure, zero pressure loss, no wear, large range ratio, small flow sensitivity and large flow measurement are far superior to other water meters.

BST-magW803E series electromagnetic water meter support three communications of the RS-485、GPRS、NB, can achieve remote data collection and management.

Main Feature

1. High accuracy and wide rang.

2. The start flow rate is as low as 0.001m/s.

3. The sensor adopt all-pass structure, zero pressure loss, no wear, never stuck meter.

4. Food class lining material to ensure water quality safety.

5. Lowest power loss, the use life of more than 6 years.

6. Equipped with wireless transmission module, support computer remote meter reading

7. Optional pressure measurement, and very suitable for water pipe network monitoring.

8. Sufficient alarm information: flow upper and lower limit alarm, atc alarm, low power alarm, pressure upper and lower limit alarm, excitation alarm, etc.

9. Simple operation on site, easy to use.

10. The instrument external connection port can normal work under condition of the short out, eliminating the instrument invalidation possibility of the human damage or the connection seepage.

11. The stronger interference protection function can apply the lager frequency converter equipment, and ensure the measurement accuracy.

12. Can choice insulation 485 module, convenient to connect the customers’ system.

13. According to the user needed can increase the external power supply(lithium battery pack, 24V DC power supply, 220V AC power supply)
