How should tiny liquid flows be measured

Date:2019-12-02 source:

The micro-flowmeter is a tool for measuring the micro-current.According to different parameters are divided into a variety of types, such as micro-flow electromagnetic flowmeters.

Micro-flowmeters are divided into different types according to different parameters.Take the micro-flow electromagnetic flowmeter as an example.

微小流量计测量

The micro-flow electromagnetic flowmeter is another masterpiece of Japan aichi in electromagnetic flowmeter: it is specially designed for alkali and acid liquid metering in sewage treatment and dosing, water treatment, petrochemical industry, pharmaceutical industry, pharmaceutical ratio and other harsh conditions.Ultra-low flowmeter measurement, pulsating flowmeter side, no moving parts;No need to worry about mechanical failure.

Micro-flow of gas can be measured with the thermal gas mass meter, because it is wider range, the micro-flow of liquid to use what meter.Tianjin bili technology development co., LTD. Recommends two kinds of flowmeter which can measure minute liquid, elliptic gear flowmeter and liquid turbine flowmeter.

Elliptical gear flowmeter is a volumetric meter, the minimum diameter can be DN4, the minimum flow can be measured 1L/h, can display instantaneous flow and cumulative flow, output pulse signal or current signal, 24V power supply, body material can be used aluminum alloy, stainless steel, etc.It is compact in size, simple in structure, convenient in installation and maintenance, it can measure the liquid with high viscosity, the higher the viscosity, the better the measurement effect, there is no special requirement for the straight pipe section, especially suitable for the measurement of medium with small flow and high viscosity, such as heavy oil, vegetable oil, coal tar and so on.

The minimum diameter of the liquid turbine flowmeter can also be DN4 with the minimum flow rate of 0.04m3/h. Different from the elliptical gear, it cannot measure the medium with high viscosity, but only the liquid with low viscosity and relatively pure viscosity.It is an intelligent type of velocity flowmeter, LCD head can display instantaneous flow and cumulative flow, output far current signal, 24V power supply, high precision, beautiful appearance.

If the user wants to measure the medium of small flow, he can choose between the two flowmeters according to the field conditions.
