Gas Mass Flow Meter -XZL

Working Principle
Gas mass flow meter is composed by gas flow sensor and digital display totalizer which brings in the US Micro-Bridge Technology.
Gas mass sensor is based on the principle of the direct proportion in heat quantity between gas mass sensor and output voltage, and transform the gas flow rate and pressure into analog signal output.
The function of Digital totalizer is to transform the analog signal into digital signal through the internal singlechip A/D. Then transform the gas mass into the standard volume flow rate after calculating the data. Last but not the least, caculating the total flowrate and the instantaneous flowrate to 4Nos and 8Nos display.
Digital totalizer can also transform the analog electric signal of gas pressure into 3Nos display through the digital tube after numbers of caculating and transform.
Besides, singlechip can calculate all kinds of normal data and the upper&lower limit of flow rate&pressure. These data could be store forever. Singlechip can also store the total flow rate into the EEPROM memory machine. All the above data could be automately store when power cut; Get back when the power recover. After the power recover.
