Product Description

1.Product overview:
Ultrasonic water meter is developed based on ultrasonic measurement of propagation velocity difference method. An ultrasonic signal is emitted to the fluid through the sensor,  An instrument that transmits an ultrasonic signal through a sensor to a fluid and then receives the ultrasonic signal after it is affected by the flow of the fluid and applies the result to a flow measurement. The instrument integrates measurement, integration and display, and adopts micro-power consumption technology, can achieve the minimum flow 0.0125 accurate measurement, At the same time, the instrument has the characteristics of small volume, good stability and strong anti-interference ability. Ultrasonic flow measurement technology can realize multi-angle installation, the instrument measurement is not affected, and the pipeline pressure loss is minimized.The product conforms CJ/T 434-2013 to the standard of ultrasonic water meter.

3.Installation precautions:

The installation of pipe sections should meet the following conditions:
Avoid installing machines in places where water pumps, high-power radios, and frequency conversions are located. That is, avoid installing the machine where there is strong magnetic field and vibration interference.
The pipe should be uniform and dense, and the pipe section that is easy for ultrasonic transmission.
The installation point of the upstream straight pipe section must be greater than 10D (Note: D=diameter), and the installation point of the downstream straight pipe section must be greater than 5D (see the figure below).
The upstream installation point should be 30D away from the pump.
The fluid should fill the pipe.
There should be enough space around the pipeline to facilitate the operation of on-site personnel.
4.Design and function
transducer: the main signal generating module, using imported piezoelectric ceramic which guarantee the stable function, consistency and high precise measurement.
temperature sensor: using pt-100 high precise platinum resistance and measurement circuit of high precision is also equipped for better measurement.
self diagnosis function: if communication errors, low battery or intentional damage is detected in the working process of ultrasonic heat meter, the system will display the errors in relating code and malfunction will be seen in the top right corner of the screen. all the data will be stored automatically and switch back after the malfunction is eliminated.
nice appearance, capable of being hanged in all four directions. easy to read and operate.
easy to install. dust-proof, moisture-proof, water-proof, anti-disassembly, better prevention of vandalism.
