The installation method of multi-channel trace gas flowmeter usually includes the following steps:
1. Preparation work
Ensure that the installation environment meets the working requirements of the flowmeter, such as temperature, humidity, power supply, etc.
Check if the accessories of the flowmeter are complete, including cables, connecting pipes, fixed brackets, etc.
2. Installation location selection
Choose a suitable installation location to avoid interference such as vibration, strong magnetic fields, and high currents.
The installation position of the flowmeter should be far away from the sudden flow change area of the gas source, avoiding blind spots and excessive bending to ensure measurement accuracy.
Ensure that the flowmeter is installed at a suitable height for easy operation and maintenance.
3. Pipeline connection
Ensure that the connection between the installation pipeline and the flow meter is well sealed to prevent leakage.
Use appropriate pipe sizes and materials to ensure the measurement range of the flow meter matches the fluid type.
For multi-channel flow meters, each gas pipeline should be independently connected and correctly connected according to the channel identification.
4. Install bracket
Use brackets or other fixing methods to securely fasten the flow meter to the pipeline.
Ensure that the flowmeter is installed correctly in the vertical or horizontal direction, and follow the requirements in the equipment manual for installation.
If vibration prevention is required, shock-absorbing brackets can be used for installation.
5. Electrical connection
Connect the power line, signal output line, and control line correctly according to the electrical wiring diagram of the flowmeter.
If it is a digital signal output, ensure that the connected control system can receive and process the corresponding signal.
Ensure that all electrical connections comply with electrical safety standards.
6. Gas source testing
After installation, conduct a gas flow test to check if all channels are working properly.
Adjust the settings of the flowmeter to ensure that its measurement accuracy meets the requirements.
Pay attention to checking for gas leaks to ensure the sealing of the flowmeter in working condition.
7. System debugging
Perform system debugging to verify whether the traffic of each channel is stable.
Adjust the flow settings of each channel to ensure accurate measurement of the flow meters in each channel.
Check the display screen of the instrument or the connected control system to confirm that the output of the flowmeter matches the actual flow rate.
8. Final inspection and acceptance
Ensure that all joints, pipes, connecting cables, etc. are securely connected without looseness or leakage.
Check whether the flowmeter display screen or control system is displaying normally, and whether there are any alarms or error prompts.
After the installation is completed, conduct final acceptance and record the data during the installation and debugging process for subsequent maintenance and troubleshooting.
According to the actual installation environment and flowmeter model, there may be additional requirements. It is best to refer to the flowmeter's product manual before installation.
