Figure 22 on page 68 for an illustration of the proper distances to measure in a typical installation In some situations only one of the required distances can be directly measured When this happens a knowledge of the installation angle 0 of the transducers permits the second distance to be calculated from Equation C 1 below E cos0 C 1 YO As an example assume that the transducer installation angle is known to be 45 and the L distance is measured to be 10 00 inches Then the P distance is calculated to be P 10 00 0 707 14 14 inches With a Bias 90 transducer installation it sometimes happens that the only known parameters are the transducer angle 0 and the centerline distance between the transducer bodies CL In these cases it is still possible to calculate P and L by combining Equation C 1 above with the additional Equation C 2 below see Figure 22 on page 68 P CL 1 2 C 2 Standard GE 90 transducers have the face offset from the centerline of the body by 0 6 inches Thus a pair of transducers has a total offset of 1 2 inches as indicated in Equation C 2 above For example suppose that the transducer installation angle is 30 and CL is measured to be 12 00 inches Then P 12 00 1 2 10 80 inches and L 10 80 x 0 866 9 35 inches DigitalFlow XGS868i Startup Guide 67 Appendix C Measuring P and L Dimensions 180 Installation Pipe Thickness
