Cloud online operation verification method of flowmeters based on indirect verification method

In the heat supply physical equipment network, in addition to the different scale flowmeter groups, there are also a large number of flow-related equipment and components. This paper studies the method of determining the working status of the verified flowmeter using the mechanism of heat supply system, the relevant parameters of the verified flowmeter, and the equipment and components with flow characteristics set up in the heat supply physical equipment network. On the basis, the cloud online operation verification technology process of the flowmeters is proposed to judge whether the technical performance of the flowmeters applied online meets the usage requirements, solve the problem of heat supply enterprises with insufficient verification personnel and verification instruments and equipment, and effectively improve the data quality of smart heating system and improve the safety of the control system.
