T3: Temperature after condenser. Dryness Fraction (sometimes called steam Xmin is the lower dryness limit. Alarm 1 indicates the limit has been exceeded. Range is quality or moisture content) 0.85–0.95. Default is 0.95. Armstrong International IOM-246-V2.0 Page 3 of 14 Steam QM-3 Calibration... -
Page 6: General Information
The pressure sensor is calibrated by simulating the voltage created at a specific pressure. Heating Element: It is important to calibrate the natural resistance of the heating element and cable with the Steam QM-3 computer. This is done by measuring the actual resistance. - Page 7 There are a total of nine instruments that need to be calibrated on the Steam QM-3. The instruments are: • 3 temperature sensors • 1 pressure transmitter • 1 heating element • 1 condensate flow meter • 1 gas flow meter (NCG meter) • 2 differential pressure sensors Differential Pressure Sensors Pressure transmitter Heating Element ∆P1 ∆P2...

Calibrating the Temperature Sensors Calibration #1: Calibrating T1, T2, T3 Temperature Sensors Turn off the Steam QM-3 and be sure it is cold. Check that the voltage switch is in the correct position for the voltage being used. Unplug the Temperature Sensor T1 from the QM-3. - Page 9 The correction is written alongside with an explanation if necessary. The correction is signed and dated. To reduce the time, part of calibration can be done simultaneously. To reduce the time, part of calibration can be done simultaneously.

Page 16: Return To Service
Return to Service The calibration procedure for the Steam QM-3 is now complete. Please follow the steps below to insure the Steam QM-3 back in operating condition. 1. Place the 1 liter draw vessel below the NCG burette and open the valve on the 1 litter draw vessel to drain the water from the NCG burette and injection assembly.
