3: Operating Procedures

Note: The

SENSOR SELECTION menu can be entered by use of the Up/Down scroll keys. This allows the

type and mode of the sensors being used to be selected. This menu will be entered automatically if the
entered pipe OD and/or temperature are not valid for the currently selected sensors.

Note: Do not press ENTER until the transducers are fitted and connected to the instrument.

Attaching and connecting the transducers

14. Fit the designated sensors to the pipe using the appropriate transducer holders as described in Paragraph

2.2. Take great care to set the separation distance as accurately as possible.

15. Connect the red and blue coaxial cables between the sensors and the instrument, ensuring that the red

connector on the instrument is connected to the ‘upstream’ sensor.

Taking a flow reading

If you need to alter the fluid temperature from
that shown, select either

°C or °F with the cursor

and press the

ENTER key.

Enter the new temperature value and press the
ENTER key.

The new temperature should now be indicated in
both °C and °F.

10. Select

Continue.. and press the ENTER key.

Enter Fluid Temperature

°C: 5.00

°F: 41.00

Continue..

11. The

SENSOR SEPARATION screen now displays

a summary of the entered parameters and
informs you of the type of sensor to be used, the
mode of operation, and the distance to set up
between the sensors.
In this example, it recommends type

A-ST (A

standard) sensors operating in the ‘

Reflex’

mode spaced

3.62 Inches apart.

Take a note of these details.
