Utilising advanced DSP technology, the Portaflow 220 (PF220) is the latest portable flow measurement and recording system to be added to the Micronics range of equipment.
The PF220 can display instantaneous fluid flow rates or velocity, together with totalised values.
A variable current or pulse output, roportional to the detected flow rate, is also produced by the PF220 to enable it to interface with a range of external control devices such as those found in building management or site monitoring systems.
The PF220 is very much designed with ease of use in mind. An interactive QuickStart menu, which simplifies system installation at any suitable location, together with minimal set-up requirements, means that the system can be installed and brought into service very quickly. Furthermore, the application parameters for a particular site can be saved to non-volatile memory and instantly recalled if a site is revisited for monitoring at a later time further reducing the set-up time. The flow sensors, or transducers, connected to the PF220 instrument are attached to the outside of the pipe being monitored and
provide totally non-invasive flow measurement without disturbing the existing plant equipment or process operation.
