Sensors¶

A list of the Sensors editor's attributes follows with a short description given for each one. Sensors allows you to define the mapping between the SCADA tags and corresponding model elements (tanks, pumps, valves, etc.). Based on these entries, the hydraulic model can be automatically updated based on the SCADA (telemetry) data.

The attributes from this editor are described below.

(Sensor) ID¶

This is the SCADA tag name in the table with SCADA data.

Description¶

User-defined description of the entry.

Sensor table¶

This is the name of the table containing SCADA data.

Is active¶

This option allows you to enable or disable the sensor without adding or removing it from the list.

Model type¶

This list defines how the SCADA data will be used in the automatic model update. The following options are available:

Node demand
Reservoir level
Tank water level
PRV valve setting
PSV valve setting
PBV valve setting
FCV valve setting
TCV valve setting
GPV valve setting
Pump speed setting
Pump open/closed
Open/closed setting
Valve or pump rule override
Multiple node demand with pattern
Node demand without pattern
Node demand with pattern
Special demand, not changed and with pattern based on SCADA data
Average day demand multiple demand item, constant or with pattern
Water quality baseline source strength
Ambient temperature
Global bulk reaction rate coefficient.

Model ID¶

This is the ID (MUID) of the hydraulic model element (node or link).

Multiplier¶

This entry is the multiplier "k" that will be used to multiply the SCADA value before using it in the model update. The model value = scada value * k + n.

Offset¶

This entry is the offset "n" that will be added to the SCADA value before using it in the model update. The model value = scada value * k + n.

Example¶

This entry will define a link / connection between the model storage tank "TNK-SWEETWATER" water depth and the corresponding SCADA sensor "AI_100_01" from a table "AI" and it will convert the measured water depth from "cm" into "m".
