The flow rate of liquid refers to the volume of fluid passing through a cross section of a pipe or open channel in unit time, also known as instantaneous flow rate, represented by Q. Formula: Q=Sv, unit: m^3/s or L/s. where S is the cross-sectional area (m^2) and v is the water velocity (m/s)

To measure the flow rate of high-viscosity liquid fluid glue, you can choose intelligent target flowmeter or stainless steel oval gear flowmeter.
When the measured liquid medium contains gas, it will also cause measurement errors.

Flow meter is a professional automatic measuring instrument, its main function is to measure the flow of fluid, and the measuring medium
includes liquid, gas, steam, mixed slurry, solid dust, etc.
It is the special function of the flowmeter. In the field of industrial automation, the flowmeter and flow sensor are called the eyes of the
automation system. The measurement results are transmitted to the upper computer system, and the system integrates and analyzes the data,
and then pre- The designed scheme is applied to the upstream and downstream control systems to achieve the purpose of intelligent
automatic control.
1. Velocity flow meter

Gas turbine flowmeter
The velocity flowmeter is a flowmeter based on the principle of directly measuring the flow velocity of the full pipe in a closed pipe. Industrial
applications mainly include:

Mass flow controllers can be used to control a variety of clean and dry gases, including corrosive and special gases, but the use of corrosive
and special gases requires the correct selection of models and sealing materials. When ordering, the user should contact the supplier to make
special instructions when using the gas, so as to avoid serious losses due to wrong selection or sealing material. Generally, the material that
the mass flow control brake contacts with the working gas is 316L stainless steel, and the sealing material is divided into metal welding, PTFE
and ordinary fluorine rubber glue. MFCs with metal welded seals for mass flow controllers can in principle be used for any gas, including
various corrosive and special gases. For highly corrosive gases such as boron tribromide, boron trichloride, hydrogen fluoride and gold used in
MOCVD
The oxidizing gas is recommended to use a metal-welded sealed MFC.
The liquid turbine flowmeter has its own characteristics, such as simple structure, few processing parts, light weight, convenient maintenance,
large flow capacity and adaptability to high parameters. It is difficult to achieve other types of flow meters.
It has the following advantages:
1. Wide range, generally 6:1, up to 40:1.
2. High measurement accuracy, good repeatability, stable and reliable.
3. Good linearity.
