Trade settlement requirements for flow meters(3)

(8) Timing meter reading function requirements. The time meter reading function is the meter reading time specified by the meter reader (pre-set in the menu), read the flow cumulative value and store it in a unit of the meter, when reading the meter When the person presses the meter reading button, the meter displays the meter reading symbol and the data in the unit. The accumulated value in this unit is maintained until the next day's meter reading time is refreshed. If the whole plant flow calculator sets the same meter reading time, then the difference between the meter reading line and the time does not affect the transcription result, so it is beneficial to the balance calculation of the table and the total table.
(9) 31-day cumulative value and 12-month cumulative value storage function. The important function of the last 31-day meter reading time, which means to protect the setting data and accumulated value when the main power supply is interrupted, so that it does not Lost and not modified.
This function provides convenience for both the supply and demand sides to check the meter reading records.
(10) Power-off protection function requirements. The power-off protection function is an important function of the programmable flow calculator. It refers to the protection of the setting data and the accumulated value when the main power supply is interrupted, so that it is not lost and not modify.
(11) Password setting function requirements . The password setting function is an important means for programmable instruments to prevent unauthorized persons from modifying critical data.
(12) Printing function requirements .Some users have suggested that the data used for trade settlement should be based on the automatic printing data of the meter, because it is more objective and will not introduce human factors due to manual meter reading. The printed content generally includes the device number, date and time of printing, instantaneous flow, cumulative flow, fluid pressure, fluid temperature, and the like.
