Utilising advanced DSP technology, the Portaflow 220 (PF220) can display instantaneous fluid flow rates or velocity, together with totalised values.
A variable current or pulse output, proportional 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.
The maximum permissible pipe outside diameter depends on the type of ultrasonic transducer in use –
- Type ‘A’ transducer – usable with pipes in the range 13 mm to 115 mm
- Type ‘B’ transducer – usable with pipes in the range 50 mm to 2000 mm
The PF220A model is supplied with the -ST Type ‘A’ transducers– usable with pipes in the range 13 mm to 115 mm, and the -PF220B is supplied with -ST Type ‘B’ transducers – usable with pipes in the range 50 mm to 2000 mm. Pipe wall temperature range for both versions is -20 °C to +135 °C.
Available to purchase is the Micronics TM8812 ultrasonic thickness gaugeas an optional accessory to accurately measure the thickness of many materias including steel, cast iron, aluminium, brass, zinc and PVC. With a resolution of 0.1 mm this simple to use device has a range of 1.2 to 200 mm and operates on x4 AAA sized batteries.
