With its advanced technology and excellent performance, Aister thermal gas mass flowmeter opens a new chapter of accurate measurement for users. Here is a detailed description of the product:

Working principle

Thermal gas mass flowmeters operate on the principle of heat conduction or heat diffusion. Inside the flowmeter, there is a heating element (such as a thermistor or hot wire) and a temperature detection element. When the gas flows through the heating element, due to the heat conduction of the gas molecules, the heating element will lose heat and its temperature will change. By measuring the temperature change of the heating element, the mass flow rate of the gas can be deduced.

  • Laboratory research: In chemical synthesis, biological culture and other experiments, precise control of gas velocity and flow rate to ensure the accuracy and repeatability of experimental results.

Installation and commissioning

The installation and commissioning process of Aister thermal gas mass flowmeter is simple and convenient, but the following points should be noted:

  • Select the appropriate installation position to ensure that there is no barrier around the flow meter to avoid eddy current effects.
  • When installing, ensure that the measuring pipe is aligned with the upstream and downstream pipes to avoid stress.
  • When connecting cables for sensors and display meters, care should be taken to prevent cable distortion or excessive bending.
  • Before commissioning, you should read the instructions carefully to understand the working principle and operation method of the flowmeter.
  • During debugging, the measurement accuracy can be ensured by adjusting the parameters of the flowmeter (such as zero point, range, etc.).

Care and maintenance

In order to ensure the long-term stable operation of the Aister thermal gas mass flowmeter, regular maintenance and maintenance are required. It mainly includes:

  • The flow meter is calibrated regularly to ensure measurement accuracy.
  • During use, strong mechanical vibration and electromagnetic interference should be avoided so as not to affect the normal operation of the flowmeter.
  • If the flow meter display is abnormal or the measurement data is inaccurate, the sensor and cable connection should be checked first. If the sensor is damaged or aged, replace it with a new one.

In summary, Aister thermal gas mass flowmeter provides users with accurate and reliable measurement solutions with its advanced technology, excellent performance and a wide range of applications.
