Ultrasonic smart water meter


   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.
    Remote reading meter, low power consumption, small pressure loss, high precision, simultaneous measurement and display of flow rate, velocity, temperature, working time and other data information, automatic fault detection alarm, M-BUS/RS485/4-20mA/NB-IoT /LORA/GPRS and other remote transmission methods.
    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.
    Ultrasonic water meter is a credible instrument for trade settlement.
    Mainly used for household measurement of residential quarters.

1. Measurement is stable, accurate, horizontal installation, vertical installation, can ensure accurate measurement.
2. The ultrasonic water meter head can be rotated 360 degrees horizontally or 90 degrees vertically. The reading is convenient.
3. It can be installed horizontally or vertically. The factory default installation is in the inlet pipe (if it needs to be installed in the return pipe, please explain in advance) .
4. Optional RS485 bus and M-Bus bus output interface. Realize data remote transmission,centralized control
5. Under voltage alarm.
6. Automatic data error correction technology.
7. Can install GPRS, data timing GPRS upload function, suitable for a variety of installation environments.
8. Flow sensor fault alarm.
9. High definition wide temperature LCD display.
10. With photoelectric interface, infrared meter reading tool can realize on-site meter reading.
11. Remote monitoring: remote meter reading.
12. Convenient installation: stable and accurate measurement, horizontal installation and vertical installation (required for vertical installation) .
13. Long service life: large-capacity battery power supply, low-power circuit design, service life greater than 6 years.
14. High protection level: IP68 high protection level design, can work in harsh environments.
15. A variety of interfaces, protocol output: MBUS / 485 interface, GPRS remote transmission, etc., convenient for users to use in different occasions.

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.



Receive signals from flow sensors and temperature sensors for flow calculation, storage, display systems, data transmission, etc.
