Flow remote transmission type electromagnetic water meter

Electromagnetic water meter is specially designed for the water industry, to meet the urban water supply to ensure the accurate calculation of water charges, widely used in the field without power supply places, such as urban water supply, sewage treatment, water conservancy engineering, water resources and other industries. Electromagnetic water meter specially designed sensor excitation system and high-performance lithium battery power supply system, and the use of 16-bit embedded ultra power consumption processor, with full digital signal processing, measurement stability, high measurement accuracy, strong anti-interference ability and other characteristics, to achieve automatic bidirectional flow measurement, on-site instantaneous flow, positive and negative cumulative total display. Self-fault alarm and GSM data wireless remote transmission and other functions, users through the powerful GSM/GPRS remote management software system can achieve the flow meter data wireless remote transmission, storage and other functions.

1.product introduction

The DG-FW intelligent electromagnetic water meter is a battery-powered electromagnetic induction water meter. Without sacrificing accuracy and performance, it can be installed anywhere, without the need for the main power supply, it is specially designed for water intake, pipe network distribution, metering and irrigation and other separate water applications, with intelligent information and high measurement performance, easy to install and save user investment, to bring users a new experience with the meter.

Equipped with an independent battery-powered GPRS transmission unit, measurement results can be sent to the "concentrator" and so on.

Application areas: secondary water supply network, large water users, zoning metering, pipe network leakage monitoring and other water monitoring and measurement.

2.Second, electromagnetic water meter technical parameters and product characteristics:

1, the instrument is simple to install - the instrument can be buried underground or installed in the well. IP68 (NEMA 6P) is designed to be unaffected by any installation position of the meter in the pipeline and does not require a filter. Low pressure loss - The straight-through measuring tube ensures low pressure loss, even at high flow rates. The pressure on the entire network system can be reduced, which helps prevent the pressure at the pumping station from getting too high, leading to pipe breaks and leaks. Zero maintenance - no moving parts design and up to 6 years battery life.

2, the display can display forward cumulative flow, reverse cumulative flow, net cumulative flow, instantaneous flow, flow direction, operating status, etc. The water meter is easy to read directly, and the main indicator value can be changed.

3. Intelligent meter - Leak detection, data logger function and error self-test can be realized with only one meter.

4, the battery can be customized imported battery, minus 40℃ can discharge normally.

5, the converter display adopts ultra-wide temperature resistant screen, temperature range: (-40℃-70℃), can be applied to extreme temperatures.

6, the use of large capacity high-end imported flash memory, sampling interval can be set in 1 to 15 minutes, the data can be stored for 3 years.

7, the electromagnetic water meter has a powerful self-diagnosis function: battery power, air pipe, excitation disconnection, signal disconnection, upper and lower flow alarm and other alarm information will be automatically uploaded to the server every 4 hours.

8, the electromagnetic water meter has the electromagnetic environment test report issued by the provincial level, in the RF electromagnetic field radiation, static magnetic field, electric fast transient pulse group, surge (impact) and other electromagnetic interference conditions, the remote transmission device does not lose memory data.
