How EMI brand ultrasonic water meter works
The Ultrasonic water meter uses the difference between the downstream and counter-current propagation time of ultrasonic pulse in the fluid to measure the fluid velocity, so as to calculate the flow of the fluid in the pipeline, and collect the temperature parameters to compensate it, so as to achieve the purpose of accurate measurement
EMI Ultrasonic water meter Functional features
- Data measurement: automatically identify the sampling frequency and sampling period when there is no water, water or flow, etc
- Real time sound path measurement (which can measure the time of the transducer in real time), transducer anomaly detection (which can effectively detect the scaling, frostbite, bubble, foreign matter adhesion, etc. of the ultrasonic transducer), adaptive adjustment of flow anomaly detection.
- Data storage: data storage of 24 monthly records and 360 daily records. The data content includes the cumulative flow (0.01M). The maximum flow rate is 0.01m/h) There is water Flow time (minutes), minimum temperature (degrees Celsius), sensor signal strength, alarm status, record generation time, etc. the data can be saved for a long time after power failure
- Status alarm: low voltage alarm, air traffic control alarm, countercurrent alarm, low temperature alarm, world leakage alarm, pipe burst alarm, etc
- With valve control function, prepayment can be realized
- Support infrared reading and parameter setting. Upgrade and other functions
- With NTC and PT1000 temperature
- DN15 to DN300 full series caliber dual channel design can meet the needs of different scenes
- Support OTA online upgrade
