ACF-1-xxx is the multivariable DP flow meter with the years of sensor technologies accumulation and full concentrations. It is the overall combination of sensor, static-pressure sensor, temperature sensor and flow totalizer, and could constitute the integrate differential pressure flow meter with the cooperation of integrative differential pressure throttling detection device——(such as: V-cone，nozzle, Orificeplate, averaging pilot-tube Annubar etc.); the gauge can display the volume of measured mediums or instantaneous flow and integrated flow of the measured mediums (such as: natural gas, steam, coal gas, compressed air, nitrogen, oxygen, gases or fluids such as water) according to the mathematical model of the mediums. It adopts micro power design, and standby battery is built-in to ensure trade measurement safety, the RS485 communication function and (4-20) mA standard output are provided, the gauge is the revolutionary innovative product in differential pressure flow meter system, and is superior to traditional instruments.
