Page 1 Page 5/6 Page 7 Page 13 Page 26 Page 28 Page 34 Page 39 SECTION 1 - INTRODUCTION General The Barton Model 202E single DP Flow Recorders measure and record system operation parameters, including gas and liquid flow rate, liquid level in a vessel, and other system variables that can be measured by differential pressure and static pressure methods. Main Components Differential Pressure Unit The Barton Model 199 Differential Pressure Unit (DPU) actuates the recorders. The DPU is a dual bellows assembly enclosed within pressure housings. The bellows are liquid filled and withstand overranges equal to the working pressure of the housing without calibration change. Movement of the bellows is transmitted through a torque tube from the DPU to the recording mechanism. The torque tube is hermetically sealed to eliminate friction and leakage; it does not require lubrication. SAFETY Before installing this instrument, become familiar with the installation instructions in Section 2. WARNING notes that appear on the following pages of this manual should be reviewed before proceeding: 8, 20, 21, 22, and 25. WARNING notes indicate the presence of a hazard which can cause severe personal injury, death, or substantial property damage if warning is ignored. CAUTION notes indicate the presence of a hazard which can cause moderate personal injury or property damage if warning is ignored. 4HE $05 IS ATTACHED TO THE BACK OF THE RECORDER CASE 4HE TORQUE TUBE IS INSERTED THROUGH A HOLE IN THE CASE AND CONNECTED TO THE $0 DRIVE ARM OF THE RECORDER MECHANISM -OVEMENT OF THE BELLOWS IS TRANSMITTED BY THE $05 DRIVE ARM TO THE TORQUE TUBE AS A ROTARY MOTION WHICH IN TURN ROTATES THE RECORDER MECHANISM 4HE PRESSURE HOUSINGS OF THE $05 ARE CONNECTED BY PIPE OR TUBING TO THE HIGH AND LOW PRESSURE SIDES OF THE PRIMARY DEVICE LOCATED IN THE PROCESS SYSTEM 4HE RANGE OF THE $05 IS DETERMINED BY THE FORCE REQUIRED TO MOVE THE BELLOWS THROUGH THEIR NORMAL RANGE OF TRAVEL 4HE 2ANGE 3PRINGS WHICH ARE AVAILABLE IN VARIOUS RANGES BALANCE THE $0 APPLIED TO THE UNIT 4HE NUMBER OF SPRINGS AND THEIR RATINGS DEPENDS ON INDIVIDUAL $0 RANGE REQUIREMENTS 3EE "5!

Arrange the differential pressure linkage as shown on page 12. Set a 90° angle between the drive arm and link. By varying the length of the link, set a 90° angle between the range arm and link. Slip the range arm to 50% on the chart. Remove pressure. The pen should indicate zero. If the pen deviates less than 10% from zero in either direction, perform fine adjustment by using the pen zero adjust screw (refer to page 12) and proceed to step 8.b. If the pen deviates more than 10% from zero, make adjustments as follows: a. Rotate pen arm and shaft by gripping the range arm and forcing (or slipping) the pen until it indicates zero. The pen arm and shaft should rotate at the range arm pivot point without loosening the range arm lock screw. b. Apply 100% pressure. Make the necessary adjustment by turning the range arm adjust screw counterclockwise if the pen is slightly underranged and clockwise if the pen is slightly overranged. Repeat zero and 100% adjustments until calibration at these points is achieved. c. Apply 50% pressure. The pen should be on the 50% chart line. If the pen is low, lengthen the linkage to make a correction 40 times as great in the low direction. Adjust the pen to 50% as in step 8.a. (refer to page 12). If the pen is high, shorten the linkage to make a correction 40 times as great in the high direction. Adjust the pen to 50% as in step 8.a. Assure all linkage screws are retightened. Repeat step 8 until calibration of all three points (0, 50, and 100% indication) is achieved. To assure accuracy, a nine-point calibration check (1, 24, 50, 74, and 100% ascending and descending) must be run. #HECK THE PENS TO ASSURE THAT THEY HAVE CORRECT PEN PRESSURE AS PREVIOUSLY DESCRIBED )F NECESSARY STRAIGHTEN THE PENS BY SLIDING THEM BETWEEN TWO lNGERS AND CURLING THEM IN OR OUT !DDING #OUNTERWEIGHT TO 0EN $0 2EFER TO PAGE ! &ABRICATED #OUNTERWEIGHT &OR OR 0EN &LOW 2ECORDERS $ISCONNECT THE DRIVE LINK FROM THE RANGE ARM 2EMOVE THE PEN FROM THE PEN MOUNT NOTE APPROXIMATE POSITION FROM RANGE ARM 2EMOVE THE RANGE ARM FROM THE SHAFT AND SLIP THE COUNTERWEIGHT TO ABOUT MID POINT 0OSITION APPROXIMATELY AS SHOWN ON PAGE AND SECURE IN PLACE 2EPLACE THE RANGE ARM TO APPROXIMATE POSITION NOTE STEP AND SECURE IN PLACE 2EASSEMBLE IN PEN MOUNT AND PREPARE FOR CALIBRATION &OR 0EN &LOW 2ECORDERS $ISCONNECT THE DRIVE LINK FROM THE RANGE ARM 2EMOVE THE PEN FROM THE PEN MOUNT 3LIP THE COUNTERWEIGHT OVER THE SHAFT IN FRONT OF THE PEN SHAFT LENGTH IS APPROXIMATELY AND POSITION APPROX AS SHOWN ON PAGE AND SECURE IN PLACE 2EASSEMBLE IN PEN MOUNT AND PREPARE FOR CALIBRATION " $IE #AST #OUNTERWEIGHT 4HESE COUNTERWEIGHTS SLIP OVER THE PEN SHAFT WITHOUT DISASSEMBLY 4HIS IS APPLICABLE TO A PEN OR PEN ASSEMBLY 2EMOVE LOCKSCREW FROM COUNTERWEIGHT 3LIP OVER SHAFT AT ANY CONVENIENT LOCATION 2EPLACE LOCKSCREW CARE FULLY ORIENTING THE COUNTERWEIGHT IN THE POSITION SHOWN ON PAGE .OTE 4HE COUNTERWEIGHT IS DIE CAST ZINC SUBJECT TO BENDING IF TOO MUCH TORQUE IS APPLIED TO THE LOCKSCREW # #ALIBRATION !FTER REMOVAL OF THE RANGE ARM COMPLETE RECALIBRATION IS REQUIRED )N THE PREVIOUS SECTION #!,)"2!4)/. /& $)&&%2%.4)!, 02%3352% 0%.
