2. Types and principles of flow meters
Flow meters can be divided into the following categories based on measurement principles:
1. Mechanical principles: Instruments belonging to this category include differential pressure type and rotor type using Bernoullis theorem;
; The impulse equation and movable tube equation using the momentum theorem; Using the direct mass formula of Newtons second law; Target based on the principle of fluid momentum; Turbine type using the angular momentum theorem; Vortex type, vortex street type, etc. utilizing the principle of fluid oscillation.2、 Electrical principles: Instruments used for this type of principle include electromagnetic, differential capacitive, inductive, strain resistance, etc.
3、 Acoustic principles: There are ultrasonic and acoustic (shock wave) methods that use acoustic principles for flow measurement.
4、 Thermal principles: There are various methods for measuring flow rate using thermal principles, such as calorimetry, direct calorimetry, and indirect calorimetry.
5、 Optical principles: Instruments such as laser and photoel
