1. Application Scenarios
Water supply and drainage flow measurement, network zoning metering DMA, large water user trade settlement, energy metering system flow measurement;
Micro-power data output, real-time data online.
2.technical characteristics
1. Equipped with 485 communication interface, it can communicate with GPRS communication module or host computer to realize remote transmission of measurement data and alarm data.
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.
