This form contains the primary information on a reading point.

For rules on how to use the fields, see Detail form.

 

Description and assignment of a reading point

• Reading point: Identifier of the reading point. It is unique in the application. This is initialized by the application, but you can change it to a more meaningful code.
• Name: Name of the reading point; it must identify the reading point,
• Structure point or Asset: Equipment to which the reading point is linked. You must only fill in one of these two fields. You can select it from the list of structure points or Assets by clicking on .
• Organization: Organization to which the reading point is assigned. As default, that of the connected user.
• Energy point: Energy point to which the reading point is assigned. 

Description of a reading point

• Template: To be selected from among the existing Reading point templates. If the template is selected, the type, template name, unit, no. of decimals, minimum and maximum values, type of cost, and unit price fields are filled in with the values defined for this template. These values can no longer be changed.
• Actual meter: Checked if the reading point is linked to a physically existing meter. Unchecked for a fictitious meter. In general, a fictitious meter is fed by a linked real meter (see Reading point [Links]).
• Type: A reading point is a "simple" or "meter" type.
  • Select "meter" if the reading point has a value that always increases. You can then use it (among other things) to track costs.
    Upon reaching the maximum value, a meter will return to the minimum value.
    The upper and lower limit values and linked actions are inaccessible in this case.
  • Select "simple" if the reading point has a fluctuating value to be monitored and is not linked to a cost.
    In this case, the type of cost, unit price, cost center, average trend, and period fields are not accessible.
• Unit: The name of the reading unit to be selected from among the units defined for the application.
• No. of decimals: Number of digits after the decimal taken into account in the reading values. Enter 0 if the readings are always whole numbers.
• Minimum Value and maximum Values: These are the limits of the authorized reading values. In the case of a reading point that returns to zero once the maximum value has been reached, such as an electricity meter (which will be a "meter" type), the minimum value is 0 and the maximum value is the one at which it returns to zero. These fields are required. If you do not have a precise maximum value, enter a very high number.
• Readings period: Indicative time between two readings (this value is not involved in the readings).
• Category: Value (from an editable list) allowing you to classify reading points.
• Regression forbidden: Check this box for meters whose value cannot decrease over time. If this box is checked, it will be impossible to enter a reading value less than the previous one, unless it is a correction.
• BL.Predict synchro: Check this box if this reading point has to be synchronized with BL.Predict so that reading point readings can be sent to BL.Predict.
  This checkbox is visible if the CARL Source/Global/Visualize BL.Predict data profile right is activated.

Case of a "Reading point"

• Type of cost: Type of cost to which the cost of the measured values is attributed. The cost type is to be selected from a list whose settings can be set by the application administrator (see Values list).
• Unit price: Price of the unit of measure. For example, with an electric meter you enter kWh as the unit and €0.50 if the price is 50 cents per kWh.
• Cost center: Cost center for measured values.

 

Average trend

These values are used in the work order plans to extrapolate the current value based on the last available value; see Trigger: Principle.

• Extrapolation:
  • "Linear": Variations in the meter are considered to be even over the course of the year. Fill in the value and the trend period.
  • "Custom": Variations in the meter are even and can be evaluated for each month in the year. They are to be filled in on the [Forecast variations] tab.
• Value and period: Average increase of the meter reading in n days, where n is the trend period.
• Auto calculation: This box is accessible only if the Extrapolation field is set to "Linear". If this box is checked, the average increase in the meter reading will be calculated automatically when the "CALCULAGING" job is run, based on previous readings.
  • When this automatic job is run, for each reading point affected (with the "Auto calculation" box checked), the process updates the fields in the "Average aging" section as follows:
    • Period (d) = job setting period
    • Value = average (variations/days) x period in days
      The calculation of the average is described below in the "Calculating linear extrapolation" section.

Simple" case"

• Monitoring lower limit and upper limit: Values beyond which the linked equipment requires monitoring. At the time of the readings, if the entered value is beyond one of these limits, a warning message will be displayed.
  • The lower limit must be greater than the minimum value,
  • The upper limit must be less than the maximum value.
• Correction lower limit and upper limit: Values beyond which the linked equipment requires a correction.
  • The lower limit must be greater than the minimum value and less than the monitoring lower limit,
  • The upper limit must be less than the maximum value and greater than monitoring upper limit.
• Issuing a WR: If this box is checked, a meter reading with a value not exceeding the correction lower limit or with a value of not less than the correction upper limit, triggers the creation of a WR, sent to the person in charge of the equipment.
• Send an e-mail: If this box is checked, a meter reading with a value beyond the correction limits will trigger the sending of an email to the person in charge of the equipment, if the message template is configured.

 

Last reading

• Value and date: this information is filled in by the application according to the readings taken at the reading point. You cannot change them on this screen, but rather by taking another reading (see Taking a meter reading).

ADDITIONAL ACTIONS

record reading points

• To enter a meter reading on the reading point, select [Record reading points] from the actions menu .

Calculate the linear extrapolation

 CARL Source provides the possibility of calculating the linear extrapolation value of the meter based on previous readings.

• To start the automatic calculation of the average increase in the meter reading, select [Calculate linear extrapolation] from the actions menu .

This action updates the Value field (only) of the "Average aging" section as follows:

• Value = average (variations/days) x period in days
  Details of the average calculation are given below.

 

Average calculation:

1. Count the number of days between the first and last readings with the exact time (e.g. 10.17 days).
2. Calculate the sum of the variations by excluding the first variation: [(n+1)+(n+2)+...(N)] (e.g. 203.4 km).
3. Divide the result of step '2' by that of step '1' to calculate the average value per day (e.g. 203.4/10.17 -> the average is 20km/day).
