Inputs
The following inputs are necessary for calculating heat flow.
Use the ▲
and ▼ keys to select the parameter to be updated, and the ◄ and ► keys
to change the value of the highlighted field. Units for the inputs are driven
by what was last set in the Pressure and Flow Measurement screens (with
the exception of specific heat).
T1 The upstream fluid temperature of the device being
measured.
Note: The upstream temperature can be entered as a
real-time measurement if the accessory
temperature probe is connected. With the value for
the upstream temperature highlighted, press the
READ key. The field will begin updating with
measured values of temperature. Press the READ
key again to discontinue real-time updates.
T2 The downstream fluid temperature of the device being
measured.
Note: The downstream temperature can be entered as a
real-time measurement if the accessory
temperature probe is connected. With the value for
the downstream temperature highlighted, press
the
READ key. The field will begin updating with
measured values of temperature. Press the READ
key again to discontinue real-time updates.
Flow
The flow rate through the device.
Note: The flow rate through the device can be entered
as a real-time measurement. With the value for
flow highlighted, press the
READ key. The field
will begin updating with calculated values of flow.
Press the
READ key again to discontinue real-time
updates.
