The non-full pipe flow meter is a kind of automatic flow measuring instrument that continuously measures the fluid flow in open pipelines (such as half-pipe sewage pipes and large flow pipes without overflow weirs) by using the flow rate-area method. It can measure and display the instantaneous flow rate, flow rate, cumulative flow rate and other data. It is especially suitable for the needs of measuring places such as municipal rainwater, waste water, sewage discharge and irrigation water pipes.

Electromagnetic Flowmeter is a speed instrument for measuring the volume flow of conductive medium. It can output standard current signals for recording, adjustment and control while monitoring and displaying on the spot, so as to realize automatic control of detection and remote transmission of signals. It can be widely used in the flow measurement of conductive liquid in tap water, chemical industry, coal, environmental protection, textile, metallurgy, paper making and other industries.
