    13 Typical faultinesses and methods of their elimination While in operation, the meter constantly checks both the working capacity of its units and the working capacity of sensors (flow sensors, temperature sensors, etc.) connected to the meter. Diagnosed errors are subdivided into groups according to a priority (importance for rea- lization of correct measurement).

If ТS with an error is involved into flow rate measurement process, then all measure- ments in the proper flow measurement channel would be canceled.

    Appendix M How to set hydraulic zero Setting of hydraulic zero is necessary for exception of a systematic measurement error. It is possible occurrence can be caused by difference in manufacturing and real conditions of setting zero. This phenomenon appears as non-zero meter indications when the real flow velocity is equal to zero.
  • Page 68 − the level of electromagnetic interference created by surrounding equipment, should not exceed a permissible level for the meter. Before hydraulic zero setting it is necessary to run the water meter in waterworks on the maximal water flow rate for half an hour, then to cut off a valve after flow measurement sec- tion, to cut off a valve before flow measurement section.
