The characteristics and operation method of the air volume meter

The air volume meter is a multi-function pressure air volume meter with high measurement accuracy, stable performance and easy operation
.

The instrument can measure pressure and differential pressure, and with a pitot tube, it can directly read the wind pressure, wind speed and air volume of the pipeline
.

The characteristics of the air volume meter: 1.
Double display of the measured value in the open-die liquid crystal, and the indication of the numerical unit
.

2.
Direct reading of pressure, wind speed and air volume, and display of ambient temperature
.

3.
You can input the skin deducting coefficient, air density and air duct area
.

4.
Battery power icon indication, overpressure range indication
.

5.
The instrument is equipped with automatic temperature compensation and intelligent numerical stabilization functions
.

　　7.
High resolution, high precision, high stability, measurement value storage and query
.

　　8.
Adopt imported micro-pressure sensor, ultra-low power consumption microcomputer, high-performance instrument integrated amplifier
.

　　9.
Fully digital circuit design touch buttons, digital zero adjustment, and measurement data storage and query functions
.

　　Operation method of the air volume meter: 1.
Power-on state: Press the power switch key, the instrument enters the initialization state, and the measurement can be performed after the displayed data is stable
.

　　2.
Clear: in the measurement state of air volume, wind speed, pressure and temperature, press the reset button to clear the initial value of the pressure
.

　　3.
Setting of pitot tube coefficient, air density, and tuyere area: press the setting key, when the display shows the pitot tube coefficient, press the right key, each time it is pressed, the digital cursor moves one digit to the right
.

Press the up key, each time it is pressed, the number will move up one place
.

Each time the shift key is pressed, the number scrolls down one place
.

After setting, press the setting key again, the method of setting the air density is the same as above; press the setting key again, the method of setting the air outlet area is the same as the above
.

　　4.
Pressure connection: The measured pressure can be introduced into the gas circuit of the instrument through the inlet of the instrument by using the gas pipe
.

　　5.
The instrument is set to zero before measurement.
6.
After the air volume meter is set to zero, it can enter the measurement state, apply the measured pressure, and the instrument will display the corresponding value of the measured fluid
