1. What are the commonly used flow meters?

Hello, the American manufacturer of KNKE flow meters is pleased to answer your question! The following is a summary of the commonly used flow meters by American customers of KNKE, based on an interview with engineers from the commonly used imported flow meter brand. 1. Differential pressure flowmeter is the most common flow technology, including orifice plate, Venturi tube, and sonic nozzle. DP flow meters can be used to measure the flow rates of most liquids, gases, and vapors. The DP flowmeter has no moving parts and is widely used and easy to use. But after blockage, it will cause pressure loss, affecting accuracy. The accuracy of flow measurement depends on the accuracy of the pressure gauge. Volume flow meters are used to measure the volumetric flow rate of liquids or gases, introducing the fluid into the measuring space and calculating the number of rotations. Impellers, gears, pistons, or orifice plates are used to divert fluid. PD flowmeter has high accuracy and is one of the methods for measuring viscous liquids. But it can also generate irreparable pressure errors and require the installation of moving parts.

3. Turbine flowmeter imported from the United States. When fluid flows through the turbine flowmeter, the fluid causes the rotor to rotate.

. The rotational speed of the rotor is related to the velocity of the fluid. Derive the flow rate or total amount based on the average fluid velocity sensed by the rotor. Turbine flow meters can accurately measure clean liquids and gases. Like PD flow meters and turbine flow meters, irreversible pressure errors can also occur and require moving parts. 4. Electromagnetic flow meters are based on the measurem High temperature mass flowmeter manufacturer

ent principle of KNKE electromagnetic flow meters in the United States. Faradays law of electromagnetic induction proves that a conductor moving in a magnetic field will induce an electric potential. According to the principle of electromagnetic measurement, fluid is a conductor in motion. The induced potential is proportional to the flow rate and is detected by two measuring electrodes. Then, the transmitter amplifies it according to Calculate the flow rate based on the cross-sectional area of the pipeline. When a fluid with conductivity flows through an electromagnetic field, the fluid velocity can be obtained by measuring the voltage. Electromagnetic flow meters have no moving parts and are not affected by fluids. The accuracy of measuring conductive liquids is high when the tube is full. The KNKE brand electromagnetic flowmeter from the United States can be used to measure the flow velocity of slurry fluids. 5. Ultrasonic flowmeter. The propagation time method and Doppler effect method are commonly used in ultrasonic flowmeters to measure the average velocity of fluids. Like other speedometers, it is an instrument for measuring volumetric flow rate. It is an unobstructed flow meter, and if the ultrasonic transmitter is installed outside the pipeline for measurement, there is no need to insert it. The KNKE brand from the United States is suitable for almost all liquids, including slurries, with high accuracy. The vortex flowmeter is a non streamlined vortex generator placed in the fluid, and the velocity of the vortex is proportional to the velocity of the fluid to calculate the volumetric flow rate. Vortex flowmeter is suitable for measuring liquids, gases, or vapors. It has no moving parts and no dirt issues. Vortex
