Introductions
Partially filled pipe electromagnetic flow meter is a kind of volume flow meter. It was specially designed for partially filled pipe.
It can measure liquid volume from 10% level of the pipe to 100% level of the pipe. It’s accuracy can reach to 2.5%, very accurate for irrigation and waste water liquid measurement.
It use remote LCD display so users can read the flow measurement easily. We also provide solar power supply solution for some remote areas where has no power supply.

Features
- Partially filled pipe electromagnetic flow meter can measure partially filled pipe liquid flow, it is very popular in irrigation.
- Its can use solar power supply, this type is very suitable for remote areas where has no industrial power supply.
- It adopts safe and durable material, service life is longer than normal products. Normally, it can work at least 5-10 years or longer.
- We have already got food grade certificate for its liner so it can be used for drinking water, underground water, etc. Many drinking water company use this type in their big size pipeline.
- We use an accurate mini ultrasonic level meter for its liquid level measurement then the flow meter will record the liquid level and use this parameter to measure liquid flow.
- This ultrasonic level meter’s blind area is very small and its accuracy can reach to ±1mm.
