Legal analysis. If the flow rate is much lower than the minimum flow rate to ensure accuracy, it will result in no output (e.g., vortex flowmeter) or the output signal will be cut off as a small signal (e.g., differential pressure flowmeter), which is unfavorable and unfair to the supplier. In order to prevent the loss of benefits, for a specific set of thermal energy metering equipment, the supply and demand parties often agree that a certain flow value is "agreed lower limit flow" according to the flow measurement range and the range that can be achieved, and if the actual flow rate is less than the agreed value, the lower limit of the charging flow will be charged.
