1. Types of flow meters

The types of flow meters mainly include liquid flow meters and gas flow meters. The following are specific classifications: liquid flowmeter: turbine flowmeter: measures flow rate through turbine rotation, suitable for measuring clean liquids. Electromagnetic flowmeter: based on the principle of electromagnetic induction, suitable for flow measurement of conductive liquids. Ultrasonic flowmeter: It calculates the flow rate by the propagation speed of ultrasonic waves in the fluid, and has the characteristics of non-contact measurement. Coriolis flowmeter: uses the Coriolis force generated by fluid in a rotating pipeline to measure flow rate. Gas flow meter: Thermal flow meter: It calculates the flow rate by measuring the heat of gas, and is suitable for various gas media. Mass flow meter: Directly measuring the mass flow rate of gas can provide more accurate measurement results. Orifice flowmeter: using the principle of throttling to measure gas flow by generating pressure difference through the orifice plate. In addition, there are some special types of flow meters, such as flow meters shared by liquids and gases, as well as flow meters suitable for specific industries or special environments. With the development of industry and technological progress, the types and functions of flow meters are constantly being updated and expanded.

2. What flowmeter is good for slow liquid flow rate?

When the liquid flow rate is slow, it is preferred to choose elliptical gear flowmeter, electromagnetic flowmeter or Coriolis mass flowmeter that are sensitive to low flow rate.

ical gear, with high accuracy (± 0.5%~1%) and minimal viscosity impact. Suitable for high viscosity fluids such as crude oil and Mu Lu lubricating oil, and can maintain accurate measurement even in low flow rate environments. two The electromagnetic flowmeter measures flow velocity based on the principle of generating electromotive force by cutting magnetic induction lines with conductive liquid, with minimal pressure loss and the ability to capture extremely low flow velocities (such as below 0.1m/s). Conductive liquids such as acid, alkali, and salt solutions are commonly used in this type and are widely used in the chemical and water treatment industries. three The Coriolis mass flowmeter utilizes the Coriolis effect generated by fluid vibration to directly measure mass flow rate, with the highest accuracy and no interference from temperature and density. Low flow rate scenarios with strict requirements such as pharmaceuticals and food processing are preferred, but there are high requirements for installation location and liquid cleanliness.
