Types of flow meters: Diaphragm flow meter: measures the volumetric flow rate of liquid or gas media. The principle is to measure the pressure difference before and after the diaphragm. It is not suitable for liquids containing particles and is inexpensive.. Venturi flowmeter: measures the volumetric flow rate of clean or loaded liquid or gas media, measures the pressure difference generated when the fluid passes through the Venturi tube, with an accuracy of about 0.5%, and is suitable for loaded fluids. Gear flowmeter: measures the volumetric flow velocity of liquid medium, which flows between two elliptical gears and is suitable for high viscosity media. Electromagnetic flowmeter: measures the flow rate of conductive liquids, including high load or abrasive liquids, corrosion-resistant, maintenance free, and reasonably priced. Turbine flowmeter: calculates the flow velocity of gases and liquids, and the rotational speed of the turbine is proportional to the fluid velocity. It is suitable for high flow rates and requires regular maintenance. Ultrasonic flowmeter: measures the flow rate of clean, loaded, high loaded, and even viscous liquids. The sensor is not inserted into the flow rate and can be measured on-site. It is expensive and not suitable for low flow rates. Variable area flow meter: measures the volumetric flow rate of clean, loaded, viscous liquids, and clean gases, installed vertically, with a stable float height corresponding to the flow rate, providing visual readings. Eddy current flowmeter: measures the flow rate of liquids, gases, and vapors by utilizing the phenomenon of ed

dy currents generated downstream of obstacles. It is suitable for high flow rates and requires regular maintenance. Thermal mass flowmeter: directly measures the mass flow rate of clean liquid and clean or loaded gas. The principle is that the heated temperature sensor is cooled by the fluid and proportional to the mass flow rate, with low maintenance and minimal interference to the flow rate. Coriolis flowmeter: measures the mass flow rate of fluids, suitable for clean, loaded, and high load liquids and gases, and can provide mass flow rate, density, and temperature information simultaneously. It is expensive and requires large equipment. Method for selecting a flowmeter: Clarify measurement requirements: Determine the type of fluid to be measured (liquid or gas, clean or load). Clearly determine whether volumetric flow rate or mass flow rate needs to be measured. Consider fluid properties: Choose the appropriate type of flowmeter based on the properties of the fluid, such as conductivity, viscosity, and particle content. For example, electromagnetic flow meters can be selected for conductive liquids, and gear flow meters can be selected for high viscosity liquids. Evaluate installation conditions: Consider the interference of irregular areas (bends, valves, diameter reduction, etc.) in the pipeline network on fluid flow. Each type of flow meter needs to be installed on a portion of the straight pipeline to ensure that fluid flow is no longer disturbed. The length of the straight pipe in front of the flowmeter is expressed as a function of the pipe diameter, such as 10 to 30D, which means that a straight pipe length of 10 to 30 times the inner diameter of the pipe is required. Consider temperature and pressure condition
