Quick Start Procedure
The following procedure details the steps required to set up the heat meter. See the sections
referred to if you are unsure about how to install the instrument.
1. Wire the electronics up to a 12 to 24V ac or dc power supply (7VA minimum per instrument)
via the Blue and Brown wires. (See Section 5.7).
2. Establish a suitable location for the flow meter on a straight length of pipe clear of bends and
valves or similar obstructions. (See Sections 5 and 5.1).
3. Determine the pipe
internal
diameter and material.
4. Either use the table in the manual, or power up the instrument to determine the correct
separation code. (See Sections 5.2 or 6).
5. Set the sensors to the correct separation by adjusting the sensor holding screws so the sensor
can slide in the slot. (See Section 5.2).
6. Select any adaptors needed for pipes with an
outside
diameter of less than 60mm,
inside
diameter will typically be less than 50mm. (See Section 5.4).
7. Apply the Gel pads to the sensors and mount the guide rail on the pipe using the banding
provided, then remove the sensor holding screws. (See Section 5.3).
8. Plug in the flow and temperature sensors and check that flow and temperature readings can
be obtained. (See sections 6 and 7.1). The electronics can be left resting on the guidrail and
fully clipped down later once all measurements have been checked.
9. Place the temperature sensors touching each other. Wait for the temperature readings to
stabilize, indicated by no change for 30 seconds. Then zero the temperature sensors. (See
Section 5.5).
10. Attach the temperature sensors on to the pipe using the self-adhesive pads. Then use the
supplied banding
to secure the sensor to the pipe. Don’t overtighten the banding. The sensor
must be in good thermal contact with the pipe and the leads must not be under any strain.
(See Section 5.5).
11. Once good readings have been obtained any further changes, such as selecting different
units, can be made via the User Menu. (See Section 8).
12. Clip the electronics assembly on to the guide rail to complete the assembly.
13. If the Modbus interface is being used then the address and data rate of the instrument must
be set using the User Menu. (See Section 8). The default address is 1 and the default data
rate is set to 38400.
