1.5 Display and connectors
The Portaflow unit is microprocessor-controlled, operated through a menu system using an inbuilt
LCD display and keypad. It can display the instantaneous fluid flow rate or velocity, together with
totalised values.
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.
Portaflow 333 units can also act as a data logger. When operating in the data logger mode the
logged data can be output directly to a PC or printer using the RS232/USB interface or stored in the
instrument’s non
-volatile memory for downloading at a later time. Up to 98k logging events can be
stored internally.
