What should I do if the flow controller accidentally enters the liquid during operation?

What to do if the flow controller accidentally enters the liquid during operation? There are many reasons why the flow controller accidentally enters the liquid during operation. Frost and melting may cause water vapor to enter the flow controller; fuel cell applications generate water by mixing oxygen and hydrogen, and it is easy to introduce water vapor during the whole process. The sensor in the conventional thermal gas mass flow controller is set to raise the temperature of the gas to a specified range when the gas passes through. Since the heat conduction ability of the liquid is stronger than that of the gas, even if it is only an instant and a small amount of liquid appears in the gas path, It also cools the internal components quickly. When a drop in temperature is detected, the thermostat consumes more power to heat it up to the specified temperature, causing the electronics to burn out quickly. What to do after the flow controller enters the liquid? To discharge the liquid: If the fluid LF series flow controller you use enters the liquid substance, do not forget it. If the liquid stays in the gas circuit for too long, it may cause different Metals echo each other. Please place the device under vacuum as much as possible, so that the liquid is released from the tiny air passages inside the device. If the liquid contains floating particles, the dehumidification process may leave solid particles behind, which can then cause residue in the mass flow meter or mass flow controller. The chances of this residue being too heavy to interfere with the laminar flow of the gas and ultimately affect the accuracy of the measurement are very small, but if that is the case, the equipment must be cleaned with isopropanol. Gas mass flow meters or controllers are very accurate products, and improper handling will directly affect the operating conditions. If you are using a gas quality star flow controller and encounter the above situations, contact the after-sales service in time, and the engineer will disassemble the equipment, clean it and re-calibrate it. The flow controller (flow meter) is composed of a mass flow sensor, a flow diverter channel, a flow control regulating valve and an enlarged control circuit. It is made by using the heat transfer distribution effect of the flowing fluid to change the temperature distribution of the capillary wall of the measuring star, that is, the thermal distributed flowmeter, which uses the principle of capillary heat transfer temperature difference calorimetry to measure the mass flow rate of the gas, which can not be affected by temperature and pressure. . The flow signal measured by the sensor is amplified, and then compared with the set voltage, and the obtained difference signal is used to drive the control valve, and through the closed loop, the flow through the channel is controlled to make it equal to the set flow.
