B.2 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 B-5. The transducer lengths are etched on the transducers. Likewise, the lengths 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.

Equation B-5 Chord “L” Dimension

Lchord = LMeterHousin g + LMount1 + LMount2

LXdcr1LStalk1 LHldr1

LXdcr2 LStalk2 LHldr2
