Inter-Transducer Distance
An accurate inter-sensor distance is essential to locating leak positions
accurately. The accuracy of a correlation result is a reflection of the
accuracy of the distance measurement.
Note: A user can record and save data without entering the inter-
sensor distance. This is useful when making an initial, preliminary
recording at a site. If a correlation peak is obtained, a user can take
accurate measurements and enter them after recording the data.
When measuring distance, keep in mind that water mains do not always
run in a straight line or at a uniform depth. Therefore, be careful to
measure the actual pipe length.
