be input into the inside of the monitoring device 1 through the air supply pipe 22, and then the inside of the monitoring device 1 is radiated, so that the temperature is prevented from being too high after the monitoring device 1 works for a long time, then the to-be-detected gas turbine flowmeter 4 is installed on another station in the same way, Through double-station alternate detection, the testing efficiency is improved, the input gas flow is detected through the gas turbine flowmeter 4 to be tested, the output signal of the gas turbine flowmeter 4 to be tested is monitored under the condition that the signal line connection of the gas turbine flowmeter 4 to be tested is correct, if the gas turbine flowmeter 4 to be tested does not have the output signal, the monitoring display screen 23 does not display, which indicates that an amplifier or the gas turbine flowmeter 4 to be tested is damaged, the gas turbine flowmeter 4 to be tested is disassembled, the next gas turbine flowmeter 4 to be tested is replaced, when the gas turbine flowmeter is disassembled, the pressure cylinder 11 is controlled to reset through the control button 12, And then the air inlet transition pipe 8 and the air outlet transition pipe 9 are all reset, then the gas turbine flowmeter 4 to be measured is taken down, and then a new gas turbine flowmeter 4 to be measured is installed in the same way, if the gas turbine flowmeter 4 to be measured has signal output and the monitoring display screen 23 does not display, the frequency and amplitude of the output signal are tested, then the pulse signal amplification factor and the pulse signal amplitude are regulated by the regulating console 24 until the monitoring device 1 receives the output signal of the gas turbine flowmeter 4 to be measured, and the output signal is displayed by the monitoring display screen 23, and then the flow monitoring data can be received by standard equipment after the flowmeter is put into use, And reduces the monitoring error of the flowmeter by performing test adjustment.
