GE Ultrasonic Flow Meter Program Settings Menu and Their Meanings:
1. CHANNEL 2 PIPE PARAMETERS: Parameters for Channel 2’s pipe.
TRANSDUCER NUMBER 113 – Standard; this is the probe number.
WEDGE TEMP INPUT: Fixed – The method for entering the wedge temperature; “Fixed” means a constant temperature.
WEDGE TEMPERATURE: 64.0000 deg C – The temperature of the sound wedge.
PIPE MATERIAL: Steel – The material of the pipe; “Steel” refers to carbon steel.
PIPE OD: 1282.0000 Circum.mm – The outer diameter of the pipe; “Circum.mm” denotes circumference in millimeters.
PIPE WALL: 12.6999 mm – The thickness of the pipe wall.
