When V cone flow meter is installed and applied on the spot, it can adapt to the measurement of a large number of media, the application is relatively simple, the stability is high, and the installation is relatively simple. But for the site, in order to ensure the stability of the site operation, we need to carry out normal maintenance. 　　 1 , before the installation, must pass the metrological verification. In the case of confirming compliance with various technical specifications, it can be installed strictly in accordance with the installation requirements of the signal pipeline and differential pressure gauge. For different media, we must refer to the relevant standards for different installation and identification, to achieve a one-to-one correspondence. 2, when put into use , must exclude the air in the exhaust valve in the highest position of the signal pipeline 3, regular cleaning of signal lines, and differential pressure flowmeter, remove all debris. 4, put before use, check the zero position. When checking the zero position, close the two pressure valves on the meter valve and open the balance valve. If zero offset is found, the cause should be ascertained and adjusted. 5, if it is found that the differential pressure flow meter shows significant differences from the measured value, it should be fully checked and repaired, and re-measurement verification.
