Package psdi.app.meter Description

The Meter package includes MBOs that contain information about meters and meter groups. An unlimited number of meters can be created. Subsequently, meters can be attached to equipment, locations, PMs and Condition Monitoring measure points. For convenience, meters can also be grouped into MeterGroups. These meter groups serve as templates. When a meter group is specified while defining a new equipment, the meters in the group are automatically be attached to the equipment. Meter groups can also be associated with rotable items. Whenever a new instance of a rotable item is created and the rotable item is associated with a meter group, the grouped meters are automatically attached to the new component (that is, new equipment) that defines the specific instance of the newly created item. Meter information is referenced by the Equipment, Locations, PMs, Condition Monitoring and Work Order applications.

Package Specification

The MBOs included in the Tool package are:

  • Meter - This class contains specific information about each meter. A meter's type, measure unit and domain identifiers are maintained here. Valid meter types, from the METERTYPE value list, are as follows: CONTINUOUS, GAUGE and CHARACTERISTIC. The domain identifier is REQUIRED for CHARACTERISTIC meters and READONLY for all others.

  • MeterGroup - This class contains specific information about each meter group.

  • MeterInGroup - This class associates a meter with a meter group. A meter must be unique to a meter group. Rollover values are maintained in this object

Other classes included in the Meter package:

  • MeterService - This is the service class for the package. The service name and relationships originating from MBOs in this package are created by this class. The service class also contains methods requiring functionality in this package that needs to be accessed before the calling object has obtained an object in this package.

Related Documentation:

  • Equipment object - Meters are used to provide information about equipment use via measurements or monitoring points.
  • Location object - Meters can be attached to a location. (add fuller explanation here)
  • PM object - Meters can be attached to a PM. (add fuller explanation here)
  • Item object - Meter groups can be associated with rotable items. When a new instance of a rotable item is created, the meters associated with the rotable item's meter group are copied to the new rotable equipment that defines the new item.
  • MeasurePoint object - To facilitate condition monitoring, a meter of type GAUGE or CHARACTERISTIC can be attached to a meausure point. In this case, the MeasurePoint's PointName attribute will be the same as the Meter's MeterName attribute. If the meter is of type GAUGE, each meter reading will be checked against the MeasurePoint's Upper Warning, Upper Action, Lower Warning and Lower Action Limits. If the meter is of type CHARACTERISTIC, each meter entry will be checked to see if the latest observation requires action. If action is deemed necessary, a work order(s) will be generated using the MeasurePoint's PMNUM attribute as a guide.
  • Work Order object - Meter readings can be entered while entering actuals against a work order.
  • MatUseTrans - Meter readings can be entered in the Issues and Transfers application when issuing a rotable item.
  • MatRecTrans - Meter readings can be entered in the Issues and Transfers application when transferring a rotable item.
  • MoveDetails - Meter readings can be entered in when moving a rotable equipment.
