              The requirements of orifice flowmeter for medium?Xi'an Huaheng Instrument Introduction:Orifice plate flowmeter,also known as differential pressure flowmeter,is composed of primary detection parts(throttle parts)and secondary devices(differential pressure transmitter and flow indicator),which is widely used in gas,steam and liquid flow measurement.
              Standard orifice plate can adopt angular connection pressure(including ring chamber pressure and borehole pressure),flange pressure or D-D/2 pressure.
              Measuring diameter DN50-DN1200,pressure 0-16MPa,temperature 0-550 C.
              Medium:gas,natural gas(including humidity below 5%),hydrocarbons(including wet HC gas),rare gases(hydrogen,helium,argon,oxygen,nitrogen,etc.),chlorine,wet chloride gas,air(including water,SiO 2 particles and air containing other suspended matter),flue gas,saturated steam(steam,water two-phase flow),superheated steam,water,etc.Almost all liquidity media are covered.
              The orifice plate flowmeter designed,manufactured and calibrated according to the national standard does not need real-flow calibration.It has high accuracy,simple structure and low manufacturing cost.However,the pressure loss is the largest in all standard throttling devices,and it is not suitable for situations requiring low pressure loss.The standard orifice plate is widely used in petroleum,chemical,metallurgical,power and other industries.
