1. What is the name of flow detection equipment used on industrial pipelines?
Flow detection equipment on industrial pipelines is collectively referred to as flow meters (flow meters), which are divided into multiple sub categories according to different measurement principles before closing.
1. Common types of flow meters suitable for industrial pipelines (1) Differential pressure flow meters.
Based on the Bernoulli principle, the fluid flow rate is calculated by detecting the pressure difference before and after the throttling element. Typical products include orifice flow meters, Venturi tube flow meters, and nozzle flow meters. It is one of the most widely used flow detection devices in industrial pipelines, suitable for clean gas, liquid, and steam media. （2） Electromagnetic flowmeter 1 Designed based on Faradays law of electromagnetic induction, it can only measure the flow rate of conductive media without pressure loss caused by throttling components, and is suitable for pipeline flow detection of conductive fluids such as sewage, acid and alkali liquids, and slurries. (Car shortage cleaning three) Vortex flowmeter 1 Based on the principle of fluid vibration, the flow rate value is obtained by converting the vortex frequency generated by the vortex generator. It is suitable for detecting large diameter pipelines of gases, liquids, and steam, with stable accuracy and low pressure loss. （4） Turbine flowmeter 1 Based on the principle of fluid driven turbine rotation, the flow rate is calculated by detecting the turbine speed. It is suitable for clean liquid and gas media with high accuracy and is commonly used for precision measurement of small pipelines. （5） Positive displacement flowmeter 1 By

3. What types of flow meters and electromagnetic flow meters have comparable accuracy levels?
The accuracy levels of Coriolis mass flow meters, high-precision turbine flow meters, multi sound simulated loss channel ultrasonic flow meters, and high-precision volumetric flow meters (elliptical gears, waist wheels, etc.) can be basically equivalent to electromagnetic flow meters, and some high-precision models even have higher accuracy than electromagnetic flow meters.
1. Coriolis mass flow meters Accuracy parameters: The measurement error of high-precision industrial grade models can reach ± 0.05%~± 0.1%, while the error range of conventional models is ± 0.1%~± 0.5%, fully covering the commonly used accuracy range of electromagnetic flow meters from ± 0.2%~± 1%. Some specialized models have better accuracy
2. Adaptation features: Directly measure mass flow rate, not affected by the density, viscosity, and pressure fluctuations of the measured fluid, and can measure conductive and non-conductive fluids, but high concentration solid slurry will wear down the measuring tube and
