mass flow meter calibration
I. Calibration steps
Preparation
Make sure the flow meter is installed in the correct position and has been cleaned without dirt or sediment.
Check the working environment to ensure that the temperature, pressure and other conditions meet the requirements of the flow meter.
Prepare appropriate calibration tools or equipment, such as calibration liquid, standard flow meter, etc.
Determine the calibration standard or procedure, usually based on the calibration guide or national standard provided by the manufacturer.
Check the flow meter status
Verify that the flow meter is in normal working
water flow meter types
Water flow meter is a device used to measure water flow. It can be divided into many types according to its working principle and structural
characteristics. The following are several common types of water flow meters and their characteristics:
Mechanical water flow meter:
Principle: Use the kinetic energy or pressure difference of the fluid to generate torque, drive the mechanical component to rotate or swing,
and transmit it to the pointer or counter through the connecting rod to achieve the measurement of flow.
Common types: Including turbine flow meter, rotor flow meter, piston flow meter, float flow meter, etc.

Non-invasive ultrasonic flowmeter is a flowmeter that uses non-contact measurement technology. Its characteristics
and applications can be summarized as follows:
1. Working principle
Non-invasive ultrasonic flowmeter uses the frequency shift (Doppler effect) caused by the flow of fluid when the ultrasonic
signal propagates in the fluid to complete the flow measurement. It does not need to enter the inside of the pipeline, avoiding
interference and pollution to the fluid inside the pipeline.
2. Main features
Non-invasive measurement: It does

vortex flow meter working principle
The working principle of vortex flowmeter can be clearly expressed and summarized as follows:
I. Basic principle
The vortex flowmeter is a volume flowmeter that measures the volume flow rate, standard volume flow rate or mass flow rate
of gas, steam or liquid based on the Karman vortex principle. It uses the principle of natural oscillation of fluid to insert a
non-streamlined column (usually a
