A Microflow meter is also called a microfluidic flow meter or a low flow meter. The Micro flow meters we are going to discuss here mainly include gear flow meters, turbine flow meters, ultrasonic flow meters, and mass flow meters.
How to choose a suitable Microflow meter depends on your actual measurement requirements. Let us analyze it together.

The micro flow meter is a special flow meter designed to measure the micro flow using the turbine principle. It has extremely high accuracy, especially under high temperature and high pressure conditions. Due to the smart structure design, no precipitation will be formed during work, so the work of the instrument is completely “clean”.

How does micro motion flow meter work?
The micro-motion mass flowmeter is a flowmeter made according to the Coriolis acceleration theory. There is a straight tube that rotates in a plane around a fixed axis O at an angular velocity w, and a particle in the tube moves outwards along the straight tube at a speed v. Because The mass point m is in a system with both rotational motion and linear motion, so it will obtain two accelerations.
① Centripetal acceleration a, its value is rw^2 (r is the distance from the particle m to the axis O), and the direction points to the axis O. ② Tangential acceleration ac, its value is 2uw. The direction is perpendicular to a, it comes from the rotating pipe. At the same time it produces a reaction force to the pipe. This reaction force is the Coriolis force. Its calculation formula is:
Where: F is Coriolis force, N; w is the angular velocity, 1/s; u is the radial velocity in the rotating system, m/s, m is the mass of the moving object, kg.
If the density of the fluid is p, the tangential Coriolis force on any section of pipe △x is:
Where: A is the cross-sectional area of the pipe.
In the formula (3-9), pAu is the natural flow rate of the fluid, set as QM’, then the formula (3-9) can be expressed as:
From the above equation, we can know the mass flow Qm as long as the Coriolis force △F is measured. This is the measuring principle of micro-motion mass flowmeter.
Micro Flow Meter is a micro oval gear flow meter. DN4-DN10. Suitable for flow measurement of various low-flow liquids.
Micro Flow Meter has strong adaptability to the viscosity of the liquid to be measured. There is no special Especially suitable for automobile fuel consumption, boiler fuel, medicine, food, chemical raw materials, wine, milk, vegetable oil cans Accurate measurement of small flow rates of various liquids.
A low flow meter is a meter specially used to measure small flow. There are many common flowmeters suitable for measuring tiny ones. Such as differential pressure type, float type, volume type, and so on. Some of these flow meters are suitable for measuring large flow rates. It is also suitable for measuring small flow. Others specialize in designing solutions for measuring small flow rates.
Flow rate meter, also known as “flow meter”, is an instrument that measures the speed of water flow. There are many kinds of models by and flow meter. For example, there are two types of rotary cup type and rotary paddle type flow meters commonly used in hydrological stations.
Liquid flow meters refer to instruments that can be used to measure the volume flow or mass flow of liquid media.
Flowmeter is one of the important measuring instruments in process automation instruments and devices. According to the physical properties of the measured medium, it can be divided into liquid flow meters and gas flow meters.
Among them, there are many types of liquid flow meters. Common liquid flow meters are vortex flowmeter, turbine flowmeter, electromagnetic flowmeter, ultrasonic flowmeter, positive displacement flowmeter, differential pressure flowmeter, rotameter, open channel flowmeter, Coriolis mass flowmeter Wait.
There are many methods and tools for measuring and controlling liquids. But it should be selected according to the actual working conditions on-site. Every instrument that measures liquid flow has its own characteristics. Choose according to its applicable characteristics. Only in this way can the performance of the instrument be brought into play.
There are many types of flowmeters, the most commonly used are as follows: 1. Electromagnetic flowmeter 2. Vortex flowmeter 3. Ultrasonic flowmeter 4. Orifice flowmeter 5. Precession vortex flowmeter
The user must provide the following parameters to select a suitable flowmeter.
