pipes of 1500mm to 5000mm diameter,
over a temperature range -20°C to

5.2 Portaflow 330 Instrument
The Portaflow 330 is a microprocessor controlled instrument operated through a menu
system using an inbuilt LCD display and keypad. It can be used to display the instantaneous
fluid flow rate or velocity, together with totalised values, or act as a data logger. When
operating in the data logger mode, the logged data can be stored in the instrument’s non-
volatile memory for downloading to a USB key at a later time. Up to 200k logging events can
be stored internally.
The instrument can also provide a variable current or variable ‘pulse’ (volumetric or
frequency) output that is proportional to the detected flow rate. This output can be calibrated
to suit a particular flow range and used with a range of external interface devices such as
those found in BMS or site monitoring systems.
