What is the function of the grounding ring in an electromagnetic flowmeter?

The core function of the grounding ring in an electromagnetic flowmeter is to establish a stable zero-potential reference point and ensure a reliable electrical connection between the measured liquid and the sensor signal.

What type of flow meter is used to measure small liquid flow rates?

A high-frequency output volumetric flow meter is used for precise, continuous, or intermittent measurement of the flow rate or instantaneous flow rate of liquids in pipelines. It is suitable for applications involving high viscosity and high pressure, such as heavy oil, polyvinyl alcohol, and resins. It can accurately measure minute flow rates under certain conditions. The product meets the needs of most markets and can measure flow rates in industries including water, oil, food, lubricating oil, chemicals, cosmetics, fertilizers, inks, pharmaceuticals, coatings, petroleum, automobiles, adhesives, polyurethane, electrolytes, and additives.

What type of flow meter is used to measure small liquid flow rates?

Working principle of a volumetric flow meter

When fluid flows through the flow meter, a pressure difference is generated between the inlet and outlet. The rotating part of the flow meter (referred to as the rotor) rotates under this pressure difference, discharging the fluid from the inlet to the outlet. During this process, the fluid repeatedly fills the flow meter's "measuring space" and is continuously sent to the outlet. Given a specific flow meter, by measuring the rotor's rotation speed, the volume of the measuring space can be determined, thus obtaining the cumulative volume of fluid flowing through the flow meter.
