Meters for thermal energy measurement are generally electric

The billing function by time period requires that the heating company, in order to encourage nighttime energy consumption and promote the day-night balance of loads, often stipulates that nighttime energy consumption should be billed by a factor of ^). Users of steam. If they want to use gas outside the planned time period, they must pay the unplanned billing factor. The billing function by time period should also be able to meet this requirement. The electrical recording function requires that the meters used for heat energy measurement are generally electric. When the power supply is interrupted, the meters stop working, and the accumulated value can be maintained, but it will not continue to increase. Sometimes the demand side pulls off the power supply of the instrument for a period of time in order to reduce the heating fee, which is obviously not allowed. The power-off recording function of the flow calculator is to record such intentional power-off and unintentional power-off events without missing a single time. The power-down record data should be accessible through the operation keys on the instrument panel, but cannot be erased. The user can process the undercalculated cumulative value during power-off period according to the agreement between the supplier and the buyer, and according to a certain calculation method. Timing meter reading function requires the timing meter reading function is that the meter reads the accumulated flow value and stores it in a unit of the meter at the meter reading time (preset in the menu) specified by the meter reader. When the meter reader presses the When pressing the meter key, the meter will display the meter reading symbol and the data in the unit. The accumulated value in this unit is kept until the next day's meter reading time is refreshed. If the flow calculator of the whole plant sets the same meter reading time, then the difference in the meter reading personnel's tour route and time will not affect the transcription results, so it is beneficial to the balance calculation of the sub-meter and the total meter.
