Introduction of Ultrasonic Water Meter 15mm-40mm
Overview
MW-WMU Smart ultrasonic 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 eight 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 m³/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.
Ultrasound flow measurement technology is used to achieve multi-angle installation that doesn’t affect the meter accuracy, nor the system pressure loss.
Mainly used for household measurement of residential quarters.
With Lora communication mode can be connected to a concentrator. the Wireless data collector produced by our company use GSM mobile or Ethernet network for data transmission to form a wireless monitoring system. When the pipeline network runs abnormally, it can actively report the abnormal information of all the devices connected to the network.

Meter detail
Product Components:
Ultrasonic 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.
Transducer:Adopting High-performance piezoelectric devices, makes the metervery 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.
Calculator:
Receive signals from flow sensors and temperature sensors for flow calculation, storage, display systems, data transmission, etc.
