7. 2003 Introduction When programming the PIPE menu of the Model GF868 s User Program the path length P and the axial dimension 1 must be entered These parameters are determined by measurements on the actual transducer installation with P equal to the face to face distance between the transducers and L equal to the axial distance between the centers of the transducer faces The accuracy of the programmed P and L values is critical to precise flow rate measurements If GE Panametrics supplies the flowcell for the system the correct values will be included in the documentation supplied with the unit For transducers installed on an existing pipe see Figure D 1 on page D 2 P and L must be measured at the site This appendix provides instructions for properly determining these dimensions Measuring P and L Whenever possible physically measure the face to face distance P and the axial distance L between the centers of the flat faces of the transducers Refer to Figure D 1 on page D 2 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 9 of the transducers permits the second distance to be calculated from Equation D 1 below cos0 L 0 1 an example assume that the transducer installation angle is known to be 45 and the L dista
