CHAPTER 1 - GENERAL INFORMATION FLUID COMPONENTS INTL 1. General Information Description The FLT Series uses FlexSwitch technology. The FLT Series models are multipurpose measurement instruments. They are individual instruments that are capable of detecting fluid flow and temperature. They are also able to detect liquid level or fluid interfaces. The instruments have two adjustable set-point alarms as well as a built-in calibration circuit.
APPENDIX D - TEMP COMP FLUID COMPONENTS INTL Appendix D. Temperature Compensation Introduction Temperature compensation (Temp Comp) is an essential part of the FLT FlexSwitch circuitry. When the Temp Comp is set correctly, the instrument stays accurate over a process temperature range of 100 °F. The instrument is a thermal dispersion device.
FLUID COMPONENTS INTL APPENDIX D - TEMP COMP 2. Write down where the heater wattage control jumper is located on the control circuit. Refer to Figure 3-1. Remove the heater wattage control jumper and install it in position J4 [J30] (heater off). Refer to Figure 3-1 for the jumper location. 3. Remove jumpers J1 and J2 [J27 and J28] from the control circuit and set them aside. 4. Connect the DMM from TP1 (next to J1) [TP3 (next to J27)] to the right jumper post of J1 [J27]. Set the DMM to ohms.
APPENDIX D - TEMP COMP FLUID COMPONENTS INTL Figure D-1. Potentiometer and Test Point Locations for Temp Comp Procedure 1. Turn off the instrument power. 2. Install the instrument into the pipe or a test stand where it can be calibrated. Start the process media flowing at a normal rate. Cool the process media to the lowest temperature in the expected operating range. 3. Disconnect the wires leading to the sensing element (ACT, REF, COM HTR, HTR).
FLUID COMPONENTS INTL APPENDIX D - TEMP COMP Figure D-2. Sensing Element Calibration Connections 6. Stop the process media flow and make sure that the media is at no flow and then let the instrument stabilize for fifteen minutes. 7. Record the resistance values of the sensing elements and calculate the resistance differential (∆R). If ∆R does not exceed the maximum ∆R of 280 ohms then proceed with the calibration.
APPENDIX D - TEMP COMP FLUID COMPONENTS INTL 15. If the calculated Temp Comp factor exceeds the allowable tolerance by a small amount (±0.01), using the maximum Temp Comp factor may make the instrument perform satisfactorily. However, if the factor is out of tolerance by more than ±0.01 then it will be necessary to repeat the calibration to verify the result. Continue with the adjustment procedure if the second result is within tolerance. Table D-2. Temp Comp Factor Table TEMP COMP FACTOR 0.042 0.041 0.
