The Study of the Principle of Entrainment Effect of the Gas-Electric Measurement

Abstract:

This paper study an method of extension the range of gas- electric measurement. Using the effection of the high speed air flowing into the throttle orifice make out an wide rang and not be affected by the fluctuation of the gas source pressure gas-electrical measurement .The measured value of using the differential pressure sensor is greater than the value of the gas source pressure, effectively increase the effective rang. C8051F350 microcontroller with built-in 24-bit resolution AD converter, 18b20 temperature sensor, RS485 bus, and industrial computer are used to make of measuring and controlling system .
