Replace the meter electronics
The following procedure should be performed by a qualified service technician or trained
personnel. Observe all warning labels on the meter before starting this procedure.
The Daniel 3410 Series Gas Ultrasonic Flow Meter Transmitter Electronics Enclosure consists of
the following:
•
CPU Module assembly (P/N 1-360-03-014)
•
Optional I/O Module (RS-232 or RS-485)
•
I.S. Barrier Board (P/N 1-360-03-004)
•
Power Supply (P/N 1-360-03-003)
•
Backplane Board (P/N 1-360-03-07)
The Daniel 3410 Series Gas Ultrasonic Flow Meter Base Enclosure consists of the following:
•
Acquisition Module (P/N 1-360-03-013)
•
Acquisition Cable (P/N 1-360-01-595)
Should the Daniel 3810 Series Ultrasonic Flow Meter require disassembly in the field (i.e., check
boards, change switch settings, or replace boards), to prevent electrostatic damage to the
electronic boards, always use a Ground Strap while handling the circuit boards. If one is not
available, make sure you are electrically discharged before touching the boards by first touching
a metal surface such as a ground lug on the meter or a table.
