What are the installation requirements of gas mass flow controller?

The installation of gas mass flow controller is very important for flow measurement and can not be ignored. In the daily work there is not according to the requirements of the installation or installation is not standardized, or light or heavy harm to the accuracy of the flowmeter. Before installation, it is necessary to inquire the operation guide in detail and install it properly in accordance with the actual processing condition.

1. The installation site should prevent interference signals. The flow meter is driven by the magnet coil in the work, the detection signal is also from the inspection electromagnetic coil, should prevent the influence of the magnetic field, in order to obtain reasonable detection data signal.

2. In the process of pipeline solution, both sides of the flange should be parallel. The axes of the upper, middle and lower pipelines for installing sensors shall be in a horizontal line, and the flange plan shall be parallel.

3. Install the stop valve and bypass. Stop valves and bypasses are installed on the upper, middle and downstream pipes of the sensor to facilitate zero adjustment, daily maintenance and ensure that the sensor can be in full pipe condition even when it is not working. The control valve in the middle and downstream of steam flowmeter is used to monitor the flow.

4. Pay attention to the sensor installation position. To ensure that the medium to be tested can be completely filled with sensors, for liquid or activated carbon adsorption, for steam or water, for thick, dirt, high cold filter point media easy to exhaust, so the transport medium is not the same, sensor installation orientation is not the same.

The gas mass flow controller immediately measures the gas flow of the material according to the flow meter, but also can measure the hardness of the material and the indirect measurement of the environmental temperature of the material, the mass flow meter configuration software is convenient, complete functions, characteristics and price comparison is high.

1. The selection of installation parts should prevent interference signals. Sensor, intelligent transmitter installation position and cable laying should be as far as possible away from the easy to cause strong magnetic field instruments, such as high power motor, transformer equipment, frequency conversion machine equipment, etc.

2. The installation of gas mass flow controller should make the flow sign of sensor consistent with the flow direction of liquid. And make the arrow point and intelligent transmitter internal structure configuration software total flow direction consistent. Note: Mass flowmeters can be used for dual purposes. If the installation orientation and the specific flow direction are reversed, the flow configuration software in the intelligent transmitter can be changed.

3, the mass flowmeter is based on the principle of measuring pipe vibration measurement instrument, so the sensor installation should take into account the process pipe near flange on both sides (about 2 ~ 10 times the diameter of the pipe) to do firm support, prevent the instrument panel and related pipe caused by vibration. If obvious pipe vibration is unavoidable, it is proposed to protect the pipe system and the instrument panel sensor with flexible pipe.

4, because the mass flowmeter is working according to the Coriolis force principle, in order to prevent the harm of the force to the precision of measurement verification. Whether the measuring tube of the mass flowmeter is installed upward or downward, it is necessary to maintain the vertical or level between the measuring tube and the ground plane as far as possible.
