Product Description 1/2 Inch Brass Pipe Ultrasonic Water Meter DN15 Digital M-Bus/Modbus/RS485/LoRaWan/Lora Way Wired/Wireless Communication OEMUltrasonic water meterUltrasonic water meter is developed based on the principle of ultrasonic transit-time measurement technology. In other words, by using a state-of-the-art signal processing to determine the travel time difference between the ultrasonic waves, which results in highly accurate velocity measurement. The instrument integrates measurement, calculation and display. It uses micro-power technology. A battery can be used for more than 6 years and we use ER26500 default, if you have special requirement we can change it to ER34615. It can measure the minimum flow rate of 0.01 m 3 /h very accurately and according to the international standard OIML R49/MID. At the same time, the instrument has the characteristics of small size, high stability and strong anti-interference ability.Menu ContentsInstantaneous flow (m3/h), cumulative flow (m3), screen detection, table address, cumulative working time (h), date(year/month/day), caliber, software versionDisplay rangeTotal flow:0m3~+9999.9999m3Power supplyBattery powered DC3.6V (battery life is more than 6 years). Multi-CommunicationWired communication : -M-BUS -RS485 -Protocol: EN1434,Modbus,CJ188Wireless communication :-Lora : 470MHz,868MHz,915MHz -LoraWan: 470MHz,868MHz,915MHz -GPRS/GSM: Local mobile operators' support is required/needed.-NB-IoT: Local mobile operators' support is required/needed. Main componentsUltrasonic pipeline: The meter's body (pipe) structure has no mechanical moving parts and no wear/tear. Which makes it maintenance free. It is resistant to any disturbance of ripple flow, which make the measurement highly accurate. The structure of the pipe is simply built to overcome the high pressure loss and eliminates any leakage.Sensor:Adopting High-performance piezoelectric devices, makes the meter very stable and highly accurate. The reflector material is stainless steel which prevents all sediments wear resistance, impact resistance, aging resistance, high temperature resistance, corrosion resistance... etc. Actual Flow Performance ParametersDiameter.mmDN15DN20DN25DN32DN40R(Q3/Q1)R400/R250Accuracy ClassCLASS 2Permanent Flowrate Q3(m3/h)2.54.06.31016Transitional Flowrate Q2(m3/h)0.010.0160.0250.040.064Mininum Flowrate Q1(m3/h)0.006250.010.0160.6250.04LCD menu diagram:
