1.5 Quick Start Procedure
The following procedure summarises the steps required to set up the meter. Please refer to the
referenced sections for full details.
1. Identify a suitable location for the meter on a straight length of pipe clear of bends and valves or
similar obstructions (See pages 6 and 36).
2. Electronics Module:
a. Connect to a 12 – 24 VDC or 24 VAC power supply (7 W / 7 V minimum per
instrument) using the Blue and Brown wires. (See page 7).
b. Switch on and program to determine the correct separation code. (see page 11).
3. Sensor Assembly:
a. Loosen but do not remove the two sensor-holding screws to lower the flow sensors
so they can slide along the Sensor Assembly’s internal guide rail (see page 13).
b. Set the flow sensors to the correct separation (see page 13).
c. Tighten the sensor-holding screws.
d. Apply the gel pads to the sensors (see page 13).
e. Mount the Sensor Assembly onto the pipe using the supplied hose clips
(see page 15).
If the pipe has an OD less than 2 ½" (75 mm), use the adaptors provided (see page
14).
f. Remove the sensor-holding screws (see page 16).
4. Connect the two wires from the Sensor Assembly to the Electronics Module (see page 16).
DO NOT CLIP THE ELECTRONICS MODULE ONTO THE SENSOR ASSEMBLY AT
THIS STAGE. THE ELECTRONICS MODULE CAN BE FULLY CLIPPED DOWN LATER
ONCE ALL MEASUREMENTS HAVE BEEN CHECKED.
5. UBT only: Plug in the temperature sensors to the Electronics Module (see page 17) and attach
the PT100 sensors to the flow and return pipes (see Section 2.1.1, page 6).
6. Check that flow readings can be obtained (see page 18).
7. Clip the Electronics Module to the Sensor Assembly and tighten the side screw to complete
assembly (see page 19).
To use the Pulse Output features, see page 28.
To use the 4-20 mA Output, see page 29 (UFM2 only).
To use the Modbus interface, see page 30. The address, data rate, and configuration of the
instrument must be set using the Modbus Menu (see page 22). The default address is 1, the default
data rate is 38400 baud, and the default Comms configuration is 8-None-2.
