Important
Record the “L” dimension of the removed transducers which is used to update the meter
configuration after all of the transducers are replaced. Make sure you have the report sheet
containing the “L” dimension, Delay Time, and Delta Delay Time for the replacement pair of
transducers to use during the Transducer Swap-out procedure in Daniel MeterLink.
