Do you know how to solve the deviation of the mass flow meter?

Do you know how to solve the deviation of the mass flow meter? A mass flow meter is an instrument that accurately measures gas flow. Its measured value is not inaccurate due to fluctuations in temperature or pressure, and does not require temperature and pressure compensation. Thermal flow switch Thermal conduction flow switch. There is a gas flow regulating valve in the mass flow controller (MFC). The valve can adjust the flow through the controller from zero to the full scale of measurement. During the working process, there will be a flow between the inlet and outlet of the controller. Air pressure drop, or differential pressure. The working pressure difference range of MFC is usually 0.1 ~ 0.3MPa. If the pressure difference is lower than the low value (0.1MPa), the control may not reach the full scale value; if it is higher than the high value (0.3MPa), the flow rate may be closed. Cannot be less than 2%F.S. When the user uses the MFC, regardless of whether the reaction chamber the user is working in is vacuum or high pressure, the pressure difference between the inlet and outlet of the MFC should be kept within the required pressure range, and the air pressure should be relatively stable. So if the flow deviation of the mass flow controller is a very serious matter, so we need to solve the problem of deviation in time. Today, I will talk to you about the solution to the flow deviation of the mass flow controller; 1. Check the deviation Method 1. Whether there is drift in the zero point, you need to turn on the power first, and if the signal of the mass flow controller is 0, you need to use a multi-network meter to measure the output signal value and the feedback signal of the power controller; 2. Whether the gas is Pure, if the coil is polluted, the flow rate will definitely be affected. At this time, you can use high-purity N2 to clean it several times. If it still can’t be solved, you need to find a professional maintenance center to accept A/S; 3. The front end of the mass flow controller Whether the pressure reaches the calibration pressure, if the pressure of the mass flow controller is not enough, it will not reach the calibration range; 2. What problems should be paid attention to when using the mass flow meter? 1. Select the appropriate flowmeter type according to the different media, flow rate and work site; 2. Install transducers in a reasonable way according to different types of ultrasonic flowmeters; 3. Regular maintenance, often check the working status and display of the flowmeter 4. Regularly calibrate the flowmeter.

have manifold mass flow meter effects, ranging from v shape coriolis mass flow meter to insertion ultrasonic flow meter.
