mass flow meter calibration
The calibration of mass flow meter is an important step to ensure the measurement accuracy and reliability. The following are the detailed steps and precautions for mass flow meter calibration:
1. Calibration steps
Preparation:
Determine the flow meter device and standard measuring instrument.
Understand the actual process of the measured equipment.
Prepare appropriate calibration tools or equipment, such as calibration liquid, standard flow meter, etc.
Determine the calibration standard or procedure, which may come from the calibration guide or national standard provided by the manufacturer.
Check the flow meter status:
Make sure the flow meter has been installed in the correct position.
Clean the flow meter to ensure that there is no dirt or sediment affecting the accuracy.
Check the working environment of the flow meter to ensure that the temperature, pressure and other conditions meet the requirements.
Confirm whether the flow meter is in normal working condition and check whether there is any damage or part that needs repair.
Preparation before calibration:
Prepare the corresponding calibration liquid or standard flow meter according to the model and specification of the flow meter.
Make sure that the calibration liquid or standard flow meter is connected to the flow meter without leakage.
Perform calibration:
Start the flow meter according to the predetermined procedure and adjust it to the calibration mode.
Measure the flow value of the flow meter with a standard instrument and record the measurement results.
Compare the flow meter's measurement results with those of the standard instrument and calculate the error value.
According to the error value, adjust the flow meter's range control valve or sensor position and other parameters to make the flow meter's measurement results as close to the standard
instrument's results as possible.
Record data:
Record the flow meter readings and the calibration equipment data in detail.
Ensure that the recorded data is accurate, including the flow meter's response time, stability, etc.
Compare and adjust:
Compare the flow meter readings with the data of the standard flow meter.
If there is an error, adjust the flow meter according to the manufacturer's guidance or expertise.
Verify the calibration effect:
After the calibration is completed, perform a verification test to ensure the accuracy of the flow meter.
The verification test may include comparing with the standard flow meter again, or performing other accuracy tests.
Complete the calibration:
After confirming that the flow meter has achieved the required accuracy, end the calibration process.
Record the calibration results and date and fill them in the calibration certificate or calibration log.
Follow-up processing:
Clean up the calibration site to ensure that no waste or dirt is left.
Subsequent maintenance or inspection of the flow meter may be required according to the manufacturer's recommendations.
2. Precautions
Selection of standard equipment: The accuracy of standard equipment has a great impact on the calibration results. High-precision and reliable equipment should be selected.
Control of calibration environment conditions: The control of calibration environment is very important for the accuracy of calibration results. Various interference factors such as temperature and
pressure should be eliminated as much as possible.
Recording and analysis of calibration results: The calibration results need to be recorded and analyzed in order to adjust or replace the mass flow meter.
Through the above steps and precautions, the calibration process of the mass flow meter can be ensured to be accurate and reliable, thereby improving the measurement accuracy and reliability.
