Flow remote distribution type electromagnetic water meter

1.Application scenario

Water supply and drainage flow measurement, network zoning metering DMA, large water user trade settlement, energy metering system flow measurement;

Separate installation, inspection and reading table convenient.

2.Technical characteristics

1, can be equipped with pressure, temperature measurement (flow, pressure, temperature integrated installation) :

Multi-parameter monitoring and Internet of Things technology can simultaneously detect pipe network pressure, flow, temperature, etc.

2, ultra-wide range ratio: Q3/Q1=400, Q2/Q1=1.6, in line with the latest national standard GB/T778-2018

No matter the large flow during the day or the small flow at night, high precision can be achieved, and the small flow measurement is very excellent, which can solve the problem of unreasonable table selection.

3, very low starting flow rate: The minimum starting flow rate of our electromagnetic water meter can reach 2mm/s, and the real dripping can be measured. It is of great significance for the accurate measurement of small flow at night.

4, the whole machine stainless steel, submersible design: Our electromagnetic water meter is all stainless steel design, IP68 protection level, in addition to the appearance of clean and beautiful, the instrument can operate reliably under complex underwater conditions all year round.

5, super anti-interference: strong anti-electromagnetic interference ability, in a strong electromagnetic environment, to ensure accurate measurement. In the event of serious interference sources such as frequency converters and water pumps, the table can still be used normally.

6, lithium battery life of more than 6 years: self-developed electromagnetic water meter converter, its circuit board static power consumption is only 200 microamps, can truly ensure the water meter battery life of more than 6 years.

7, 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.

8, long-term stability, no maintenance, no moving parts, no wear.

9, 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.

10, 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.

11, zero is very stable: very little maintenance, to ensure that the user does not use water in the case of instantaneous flow is zero, to avoid the resulting charging disputes.

12, high precision and stable measurement: The exclusive development of the converter, the use of military quality of low noise, high precision imported components, can maintain high precision measurement at low flow rate for a long time. High performance excitation method and optimized filtering algorithm ensure fast response and high precision measurement, even when there are small bubbles and pulsating flow in the pipeline, it can also obtain stable measurement.

13. Good compatibility of meter reading system:

Our company's electromagnetic water meter has excellent compatibility with the meter reading system, remote data is fully compatible with the platform in use, can provide data call interface, can also build a standard intermediate database, the manufacturer's data is pushed to the intermediate database, the platform is responsible for displaying the data, and the remote data meets the requirements of the appendix "remote water meter communication Protocol".

14, data transmission security: Our electromagnetic water meter, its RTU can adopt full Netcom mode, support full NETcom APN access, can cooperate with the user to build APN line, to ensure data security.

15, optional meter reading mode: can be equipped with 4G module or NB-IOT module or to assist users to build their own APN line for remote meter reading, can also use 485 module directly access to the customer's industrial control system for meter reading.
