The installation requirements for a thermal gas flowmeter include selecting a suitable installation location, ensuring a straight section of the pipeline, avoiding vibration and impact, paying attention to ambient temperature, correctly connecting power and signal lines, selecting appropriate sealing materials, meeting explosion-proof requirements, maintaining a safe distance, and completing calibration and testing.Installation location selection: Direct sunlight exposure, rainwater immersion, and strong wind areas should be avoided to reduce the impact of the external environment.

Installation direction: Determine the installation direction according to the fluid flow direction to ensure the normal operation of the flowmeter.Pipeline straight section requirements: Sufficient straight pipe sections should be reserved before and after the flowmeter, usually requiring 10 times the diameter of the pipeline to be reserved before and after the flowmeter.

Avoid vibration and impact: The flowmeter should be protected from mechanical vibration and impact, and a sturdy bracket or hanging device should be selected for fixation.

Environmental temperature: Ensure that the installation environment temperature does not affect the performance of the flowmeter, and avoid environments with excessively high or low temperatures.

Power and signal lines: Connect the power and signal lines correctly, avoiding excessively long lines or being close to electromagnetic interference sources.

Sealing requirements: Select appropriate sealing materials based on the characteristics of the fluid to ensure that the fluid does not leak.

Explosion proof requirement: If there is an explosion hazard in the installation environment, a thermal gas mass flowmeter suitable for explosion prevention should be selected.

Safe distance: Maintain sufficient safe distance from other equipment and pipelines to avoid interference and affect measurement accuracy.

Calibration and testing: After installation, calibration and testing are required to ensure the measurement accuracy of the flowmeter.

In addition, the installation of thermal gas mass flow meters should also pay attention to the following points:

1. Welding operations are prohibited in explosive environments, and environments with special welding requirements should be operated in accordance with relevant requirements.

2. The base can be divided into two types based on the installation method: welding and clamping. During installation, the base should be positioned at the apex of the pipeline cross-section and the axis of the base through-hole should be perpendicular to the axis of the pipeline.

3Before installing the simplified thermal gas mass flowmeter, please confirm the actual inner diameter and wall thickness of the pipeline, and calculate the depth to be inserted based on the actual inner diameter and wall thickness of the pipeline.

4. The installation methods of plug-in thermal gas mass flow meters and pipeline thermal gas mass flow meters include horizontal installation and vertical installation.
