Summary
The purging device is composed of rotameter and constant flow valve. When the inlet or outlet pressure fluctuates to a certain extent, it can measure the flow and ensure the constant output of the flow. It is widely used in the purging of transmitters in chemical, petroleum, metallurgy, steel and other industries, as well as the purging of various analytical instruments, orifice pressure taps and the process control of differential pressure level measurement.
The flow meter, filter pressure reducing valve and pressure gauge are assembled on a panel. Since the components are all assembled on the panel, they are easy to install. When the outlet pressure fluctuates, the stable purging (gas) flow can be maintained, thus forming a panel purging device.

Installation of purging device

◆ Please select a suitable position to install the flow purging device to ensure that the flow purging device is easy to adjust, clean and disassemble.
◆ The magnetic coupling transmission system is installed on the float flowmeter of the purging device (flowmeter). Therefore, it is ensured that the interference magnetic field generated by other working equipment will not affect the measurement results of the flowmeter.
◆ During installation, to ensure the stability of the flow purging device, a fixed bracket should be added at the appropriate position
◆ The installation size should not exceed the given size too much or too little to avoid the tension and compression force acting on the flow device.
◆ When the liquid medium contains ferromagnetic particles, the magnetic particles must be filtered out in the instrument.
◆ Make sure that the fluid direction of the medium is the same as that required by the flow purging device. When installing the instrument, close all the fine-tuning needle valves to measure the liquid
◆ Before putting into operation, please empty and purge the pipeline to avoid impact.
◆ Please open the valve slowly.
Gas measurement
◆ Please open the valve slowly to adjust the pressure to the working pressure.
◆ The flow should be changed by adjusting the opening of the valve to prevent the float from suddenly accelerating and bumping against the limiter (for example, in the case of using electromagnetism), which may damage the measuring parts.
