MULTIJET WATER METER DN20 NEXTRON The water flow tangentially impacts the impeller from the water of the watch case to make it rotate, and then continuously records the number of revolutions of the impeller though the gear reduction mechanism, thereby recording the cumulative flow through the water meter.

We also supply the other type for mobile pump high pressure, see below for specification SMART WATER METER NEXTRON DN25:
FUNCTION DESCRIPTION :
- Main control chip
- Low power consumption microcontroller HC3L130.
- Basic frequency 4MHz.
- Ultrasonic Metering Function.
- Calculate the forward and reverse flow.
- Velocity of flow calculate.
- Installation direction detection.
- Empty pipe or sensor fault alarm.
- Divided into normal operation mode and mode.
- In the verification mode, the flow will be reset automatically after each re verification.
- automatically after each re verification.
- Time difference has 10 times of head and removal average algorithm,
- The flow coefficient iscompensated by the insterpolation algorithm for flow and velocity.
