Water Meter Ultrasonic Rs485 T50 Wifi Cold Home
Basic introduction
The ultrasonic water meter is a new type of water meter, which can detect the time difference caused by the speed change of the ultrasonic beam when the ultrasonic beam propagates upstream and downstream in the water, analyze the flow rate of the treated water, and then calculate the flow rate of the treated water. No moving parts inside, no current blocking elements, not affected by impurities in water, and long service life.
1.Size:DN15~D40
2.Wide range ratio, R=200,R=250
3.Wireless remote technology:LoRa/Lorawan/NB-iot/GPRS
4.Wired remote technology:RS-485 and MBus
5.Low initial flow (up to 0.0015m³/ h）
6.Water metering data history storage locally.
7.Real-time Hall counter accumulates flow.
8.Battery power and external power supply can be chosen.
9.Low battery capacity alarm,Valve failure alarm.
10.Display content: current reading, electric quantity, balance, valve status.
11.Infrared configuration:Infrared set/read meter parameters.
12.Temperature range:T50
13.Scenes to be used:home、residential、apartment etc.
Battery can work continuously for more than 8 years.
No mechanical moving parts, no wear, long service life.
IP68 protection design, which can work in water for a long time.
High stability and can work at any flow point for a long time，measure free from magnetic interference.
