What are the application scopes of differential pressure flowmeter?

Differential pressure flowmeter has a wide range of applications, which can be used to measure the flow of various objects in closed pipelines, such as fluid: single phase, mixed phase, clean, dirty and viscous flow. Working conditions: normal pressure, high pressure, vacuum, normal temperature, high temperature, low temperature, etc. Diameter: from several millimeters to several meters; Flow conditions: subsonic, sonic, pulsating flow, etc. Its consumption in various industrial sectors accounts for about 50%~60% of the total consumption of flow meters (about one million units per year). It is widely used in air conditioning system, clean room, filtration resistance, air flow detection of exhaust pipeline, wind speed, boiler furnace negative pressure measurement, fan and blower pressure measurement, pressure drop on both sides of orifice plate, liquid level measurement of bubble blowing system, hydraulic system pressure, gas and air flow measurement, automatic valve and blood flow monitoring and breath detection in medical care equipment.
