[0002] The parameter setting method of the intelligent flow totalizing controller is a method for controlling the use of the flow totalizing controller. The flow settlement instrument is displayed in full Chinese. During operation, you can directly follow the Chinese prompts of the instrument to complete the selection and setting of all parameters. The display screen supports manual touch operation. Users can choose mass flow as trade settlement or thermal flow as trade settlement. With the continuous development of science and technology, people's manufacturing process requirements for the parameter setting method of the intelligent flow totalizing controller are getting higher and higher.

[0003] The existing parameter setting method of the flow totalizing controller has certain drawbacks when in use. The existing flow totalizing controller cannot perform parameter control well when performing measurement control. The parameter setting function is relatively single and cannot adapt to more flow signals, which brings certain adverse effects to people's use process. For this reason, we propose a parameter setting method for an intelligent flow totalizing controller. Summary of the invention

When the temperature is higher or lower than this value, the instrument will display a temperature alarm. When there is no temperature signal connected on site and the temperature exceeds the limit, and the flow calculation requires temperature, the working temperature needs to be set manually.

[0023] As a preferred technical solution of the present application, the function accumulation parameters in the S9 step include micro-flow judgment. When the flow signal sent by the transmitter is less than 10% of the micro-flow value setting value, when the conditional temperature, pressure, and temperature and pressure are simultaneously greater than the set values, the flow is calculated according to the micro-flow value setting value.
