Voltage type method for testing air flow meter

Abstract

A system and a voltage type method for testing air flow meters are disclosed. The system includes an air feeding member, an air inlet duct connected to one end of the air feeding member, an air filter connected to one end of the air inlet duct, a throttle disposed on the air inlet duct and located in front of the air feeding member, a test fixture for fixing an object under test connected to a front end of the throttle and a flow sensor disposed between the test fixture and the air filter. The object under test is fixed for measurement. A mode of sample set-up or a mode of product comparison is selected and various items including heating curve, static voltage, floating voltage, acceleration curve, intake temperature, thermistor, atmospheric pressure, velocity curve, etc are measured in turn. Thus a voltage-type measurement procedure is complete.

Dependencies are inferred from the claim text.
