Chord "L" Dimension Calculation
The chord "L" dimension is calculated from the meter housing length as well as the
transducer pair lengths, mount lengths, holder lengths, and stalk lengths as shown in
Equation
of the mounts, stalk assemblies, and transducer holders are also etched on the individual
components. The length of the meter body is found on the original calibration sheet
supplied with the meter.
