Home Wireless Smart Remote Meter Reading Water Meter NB-IOT / LORA / RS485 / MBUS / GPRS / GSM

Ultrasonic water meter

Ultrasonic water meter is a new type of water meter. It can detect the time difference caused by the speed change of the ultrasonic wave when it travels in the opposite direction to the water, and analyze the water flow to further calculate the water flow. water.
Ultrasonic flow measurement technology is used to achieve multi-angle installation without affecting the accuracy of the instrument or the pressure loss of the system.
Mainly used for home measurement in residential quarters.
Use Lora communication mode to connect to the concentrator. The wireless data collector produced by our company uses GSM mobile or Ethernet network for data transmission to form a wireless monitoring system. When the pipe network runs abnormally, it can proactively report abnormal information of all devices connected to the network.
Features: low starting flow, large range ratio, high measurement accuracy and stable operation.
There are no obstacles in the internal moving parts, and they are not affected by impurities in the water. The output communication function is perfect, which can meet various communication and wireless networking requirements.
It has excellent small flow detection capabilities, which can solve many traditional water meter problems, is more suitable for water fee gradient charging, and is more suitable for water conservation and reasonable use.

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.
