Principle and structure of methanol ethanol flowmeter

The 3320 methanol ethanol flowmeter is a precision flow measurement instrument that can be used in conjunction with the corresponding flow integrator to measure the flow rate and total amount of liquids. Used in conjunction with the 7100 series quantitative controller developed by our factory, it can achieve high-precision quantitative control of liquid feeding. Widely used in the fields of petroleum, chemical, metallurgy, scientific research and other metrology and control systems. Turbine flow sensors with sanitary fittings can be applied in the pharmaceutical industry. The methanol ethanol flowmeter can also be connected to secondary instruments or controllers in the control room to achieve integration, transmission, communication, and control functions.

Product Structure of Methanol Ethanol Flow Meter

The structure of the methanol ethanol flowmeter is shown in the following figure, which mainly consists of a housing, a front guide frame, an impeller, a rear guide frame, a clamping ring, and a magneto electric induction converter with an amplifier;

Working principle of methanol ethanol flowmeter

When the measured fluid flows through the sensor, the impeller inside the sensor rotates with the help of the kinetic energy of the fluid. The impeller periodically changes the magnetoresistance in the magneto electric induction system, causing the magnetic flux passing through the coil to periodically change and generate an electrical pulse signal. After amplification by an amplifier, it is transmitted to the corresponding flow integrator for flow or total measurement.
