5.2.1. Operating Range Menu
This menu allows the user to modify the fields shown and described below. This page may look
different from your setup if the sensor quantities were only entered for one or two systems. Navigate to
this menu from the Main Screen by pressing
Setup » 1. Operating Range
.
Tagging Information
Selecting this box will provide a keypad popup to allow entry of unique System tagging information.
The tagging information will be displayed on the Main Screen and any other place indicating System 1,
System 2, or System 3 Tagging in the Setup Menus. Twelve characters can be entered as the System
tag.
Area Type
Allows user to toggle between flow calculation method for either Area or Piezometer ring equations.
Area should be selected if the MTSE is connected to a flow station or flow sensors with known cross-
sectional area. Piezometer should be selected if connected to a fan’s piezometer ring that has a
manufacturer-provided fan coefficient.
Area/Piezometer Coefficient
Allows user to enter or modify an existing Area Factor if Area is selected in Area Type. The cross-
sectional area of the flow station or duct is used to determine volumetric flow in the MTSE. If a new
Area Factor value is entered and causes the previous entered Operating Range value to exceed the
new minimum or maximum calculated full-scale range, the new area factor will be set, and operating
range will be the new full-scale maximum.
If Piezometer is selected in Area Type, allows user to enter a manufacturer-specified fan coefficient
when connected to a piezometer ring. See Standard Density below for different ways manufacturers
present fan coefficients.
Operating Range
Allows user to enter a value which will represent 100% of the process output signal also referred to as
Max on the Main Screen page. Touching this box will bring up the Keypad which identifies the
maximum and minimum values that can be entered. The maximum value is calculated at full scale
transducer span, and the minimum value is calculated using the low limit value entered by the Factory
(
Operating Range Low Limit
Default = 5% of maximum Vp value
).
