V cone flowmeter use maintenance instructions

When the V-cone flowmeter is installed in the field, it can adapt to the measurement of a large number of media, and the application is relatively simple, the stability is high, and the installation is relatively simple. However, for the site, in order to ensure the stability of the field operation, we need normal maintenance.
1. Before the installation, it must pass the metrological verification. In the case of confirming compliance with various technical indicators, it can be installed in strict accordance with the installation requirements of signal pipelines and differential pressure gauges. For different media, we must refer to the relevant standards for different installation and identification, to achieve a one-to-one correspondence.
2. When in use, air must be removed from the exhaust valve at the highest point of the signal line.
3, regularly clean the signal pipeline, and differential pressure flowmeter to remove all debris.
4. Check the zero position before putting it into use. When checking the zero position, close the two pilot valves on the instrument valve and open the balancing valve. If a zero offset is found, the cause should be identified and adjusted.
5. If the indication value of the differential pressure flowmeter is found to be significantly different from the measured value, it should be thoroughly inspected and adjusted, and the metrological verification should be repeated.
