System Configurations
The MTSE can be custom configured to match most applications to measure, sum, and report up to 3
systems and 4 ΔP points for a total of up to 9 sensing points, as described below:
System
Each System is defined as having all the following unique properties:
1.
Single or multiple transducers to measure a single point or multiple points of differential
pressure (i.e., fan array, duct, outside air, supply air, return air, or exhaust air).
a)
Multiple points are summed if measuring flow.
b)
Multiple points are averaged if measuring pressure or velocity.
2.
A single entry for a transducer span, piezometer coefficient, and/or area factor for flow
calculations, i.e., all fans or airflow measurement stations must be exactly the same.
3.
Temperature compensation and an Analog Input for a dedicated temperature sensor input.
4.
Ability to correct for “System Effect” with user defined K-Factor.
5.
Selectable operating range, engineering units, and dedicated analog output signal relative to
operating range.
6.
Adjustable rolling-average sample filters.
7.
High and Low alarms.
In addition to the (3) Systems there are also two other sensor measurement types with their own unique
properties which are described below.
Sub System (Commonly used as 2
nd
OA)
Many air handling unit manufacturers are offering dual outside air intakes for greater turndown
capability. The MTSE has the ability to measure a unique and independent 2
nd
OA intake. The 2
nd
OA
flow measurement is similar to a System as explained above, but with some key differences:
1.
The 2
nd
OA is limited to a sensor quantity of (1).
2.
The 2
nd
OA is summed into the last System, which may or may not be System 3.
3.
The 2
nd
OA has most of its own unique parameters to be entered independently from the 1
st
OA, i.e., operating range, area factor, k-factor, and alarms, but also shares the following
settings with the last system.
i.
Analog Output represents summed flow value
ii.
Filter
iii.
Temperature
iv.
Units
Differential Pressure (ΔP) Points
ΔP’s are individual pressure measurements of interest. ΔP is made available on the MTSE to monitor
things such as total fan static, duct static pressure, or filter banks – to name a few examples.
ΔP’s will have no settings other than the following characteristics:
1.
Same span for all ΔPs
2.
Same engineering unit’s selection for all ΔPs (in pressure)
3.
Individual tagging
4.
Individual Alarm Trigger (High or Low)
5.
Individual Alarm Value Setpoint
