Description:

The partially filled pipe electromagnetic flowmeter is a device independently developed by DWI specifically for the precise measurement of partially filled pipe flow. Like ordinary electromagnetic flowmeters, it uses Faraday's law of electromagnetic induction to measure flow. Through the unique low-level electrode layout and non-contact capacitive liquid level measurement, the electromagnetic method can achieve synchronous measurement of liquid level and flow rate in a non-full pipe state without the need for additional liquid level measurement devices. It is particularly suitable for the precise measurement of partially filled pipe flow in the water supply and wastewater industries.

Features:

Full pipe flow/partial pipe flow
Capacitive liquid level measurement
Level sensor integrated in the lining
Low-level electrode pair design
Standard hydraulic laboratory calibration
Wide diameter range, up to DN1200
High protection level, IP68
