Panel type dual channel blowing device

Purging deviceIt is composed of a rotor flowmeter and a constant flow valve, and is suitable for inlet orWhen there is a certain fluctuation in outlet pressure, achieve flow measurement and ensure a constant output of flow. extensiveUsed for blowing transmitters in industries such as chemical, petroleum, metallurgy, and steel, as well as for various other applicationsProcess control of analytical instruments, flushing of orifice pressure taps, and differential pressure liquid level measurement.Assemble the flowmeter, filter pressure reducing valve, and pressure gauge on one panel, as the groupAll components are assembled on the panel, making it easy to install. When the outlet pressure fluctuates, it can be maintainedStable blowing (air) flow rate to form a panel type blowing device.

Installation of blowing device

Please choose a suitable location to install the flow blowing device to ensure easy adjustment, cleaning, and disassembly of the flow meter blowing device.

Due to the installation of a magnetic coupling transmission system on the float flowmeter of the purging device (flowmeter). Therefore, ensure that the interference magnetic fields generated by other work equipment do not affect

The measurement results of the sound flow meter.

During installation, it is necessary to ensure the stability of the flow blowing device, and fixed brackets should be added at appropriate positions

The installation size should not exceed the given size too much or too little to avoid tensile and compressive forces acting on the flow device.

When the liquid medium contains ferromagnetic particles, it is necessary to filter out the magnetic particles in the instrument.

Be sure to ensure that the fluid direction of the medium is the same as the direction required by the flow blowing device. When installing the instrument, all fine tuning needle valves should be closed

Measurement of liquids

Before operation, please empty and blow clean the pipeline to avoid any impact.

Please slowly open the valve.

Measurement of gases

Please slowly open the valve to adjust the pressure to the working pressure.

Basically, the flow rate should be changed by adjusting the opening of the valve to prevent the float from suddenly accelerating, surging, and hitting the limiter (such as in the case of using an electromagnetic)

At this point, the measuring components may be damaged.
