5.5.6 Calorie Calculation
Byobtainingtheabsolutetemperatureorthetemperaturedi󰀨erencefromotherproduct
(temperaturetransmitter,etc.)fromMAO,thecaloriecalculationisexecutable.
The calorie is obtained using the following formula.
Q=c×V
m
×∆t
 Q:Calorie[J/s]
 c:Specicheat[J/kg•K]
V
m
:Massowrate[kg/s]
 ∆t:Temperaturedi󰀨erence[K]
Thetemperaturedi󰀨erenceofΔtvariesdependingontheMAOfunctionsetinSection5.4.Ifthe
temperaturedi󰀨erenceisselected,thetemperatureobtainedinMAOisused.Iftheabsolute
temperatureisselected,adi󰀨erencebetweenthetemperatureobtainedinMAOandthe
reference temperature set in Subsection 5.1.10 is used.
[“TemperatureacquiredbyMAO”–“Setreferencetemperature”]
ThisfunctioncanbeusedonlyforAXG,notforAXW.Thesettingcanbeconguredwiththe
following parameter.
