Transducer installation
Slide the lower Shroud beneath the meter body. Make sure the transducer cables are
moved out of the way and will not be pinched when the Shroud is reinstalled.
Lift the lower Shroud until the bolts align with the upper Shroud tab and notches and
the lower Shroud is flush with the top inside lip of the upper Shroud.
Install the four Shroud clamps onto the lower Shroud bolts and secure with the four hex
head nuts and external tooth lock washers. Tighten the nuts with a 7/16 inch (12 mm)
wrench.
Apply power to the meter and connect to Daniel MeterLink. Open the Meter Monitor
(Detailed) view and verity the meter is acquiring data, the transducers have good
signals and flow profiles for the chords are displayed.
In Daniel MeterLink, run the Zero Calibration utility to re-zero the meter at no-flow
conditions.
Close your connection to Daniel MeterLink and prepare to seal the meter.
Attach the security wire seals on the Transmitter Enclosure end caps and through the
hex head bolts on the Base Enclosure
Figure 3-10). Refer to the Daniel 3812 Liquid Ultrasonic Meter Installation Manual (P/N 3-
9000-765, Section 3.6.8) for detailed sealing instructions.
This completes the transducer installation procedure.
