According to the provisions of the "Measurement Law" and the "Liquid Flowmeter Calibration Regulations", the electromagnetic flowmeter in the fire pump room needs to be subject to mandatory verification on a regular basis.
1. The function and calibration requirements of electromagnetic flowmeter
Electromagnetic flowmeter as a liquid One type of flow meter, it is widely used in industry, agriculture, urban construction, environmental protection, water conservancy, hydrology, energy, petrochemical and other fields. In fire pump rooms and fire water systems, electromagnetic flowmeters also play an important and irreplaceable role. Its main function is to measure the flow of liquid in the pipeline to promptly adjust the water pressure and water supply of the fire water system to ensure the normal operation of fire protection facilities.
In order to ensure the accuracy and reliability of electromagnetic flowmeters, my country has implemented a mandatory inspection system. According to the provisions of the "Measurement Law" and the "Liquid Flowmeter Calibration Regulations", electromagnetic flowmeters require regular mandatory calibration. Otherwise, once an error occurs in the flow control of the fire water system during emergency rescue, it may have a significant impact on personal and property safety.
2. Mandatory calibration and standards for electromagnetic flowmeters
According to the relevant laws and regulations of our country, liquid flowmeters need to be factory calibrated before use and regularly during use. Test. The specific calibration cycle is as follows:
1. Calibration of the electromagnetic flowmeter before leaving the factory: The manufacturer needs to calibrate the electromagnetic flowmeter before leaving the factory to ensure its accuracy and reliability.
2. Initial calibration within one year: The electromagnetic flowmeter needs to undergo initial calibration within one year after use.
3. Two-year calibration: After the electromagnetic flowmeter has been used for two years, a two-year calibration is required.
4. Three-year calibration: After three years of use, the electromagnetic flowmeter needs to be calibrated for three years.
For specific calibration standards, please refer to the "Liquid Flow Meter Calibration Regulations".
3. Conclusion
To sum up, as an important part of the fire water system, the electromagnetic flowmeter in the fire pump room needs to be regularly calibrated. For electromagnetic flowmeters that have not undergone mandatory calibration, the fire department should promptly rectify them to ensure the normal operation of the fire water system and protect the safety of people and property.
