Operating Procedures Instruction manual
24
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.
Do not press the ENTER key until the transducers are fitted and connected to the
instrument.
Attaching and connecting the transducers
14. 14. Fit the designated sensors to the pipe using the appropriate guide rails. 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 test instrument,
ensuring that the red connector on the instrument is connected to the ‘upstream’
sensor.
Taking a flow reading
16. Once the transducers have been fitted and
connected, press the ENTER key on the
ATTACH SENSORS screen.
17. This will take you to the FLOW READING
screen via a signal-checking screen (shown
here).
18. Check that the indicated signal strength on the
left of the screen is at least 2 bars (ideally 3 or
4). If less than 2 bars are shown it indicates
there could be a problem with the transducer
spacing, alignment or connections; or it could
be due to an application problem.
Flow monitoring
The FLOW READING screen is the one most used during normal monitoring operation. It
shows the instantaneous fluid flow together with totalised values (when enabled). In this
mode you can select the flow rate measurement units by pressing keys 7 (litres), 8 (Gallons,
Barrels) or 9 (m³), or change the display to show velocity by pressing key 4.
7.4 Managing Named Sites
If you want to monitor a particular site location frequently you can set up a named ‘Site’ to
store the installation details, such as pipe dimensions and material, required to set-up the
Portaflow 330 system. These can then be recalled later when revisiting that particular
location. The instrument can store up to 20 sites, the first site is reserved for QUICK START
