Micronics PF440IP Portable Ultrasonic Flowmeter

The Micronics PF440IP Portable Ultrasonic Flowmeter, with IP67 case and IP68 transducers, is suitable for use in the most demanding industrial applications. IP68 transducers can be used to measure flow in fully submerged lines. Battery life of >150hrs continuous use. the PF440IP can be set up to take readings at 1hr intervals, allowing continuous operation for up to 4 months with one charge.


PF440IP can display instantaneous fluid flow rates or velocity, together with totalised values. It also incorporates a data logger that can record up to 198,000 datapoints which can be output directly to a PC or printer or stored in the instrument’s memory for downloading at a later time.

A variable current or pulse output, proportional to the detected flow rate, is also produced by the PF440IP to enable it to interface with a range of external control devices such as those found in building management or site monitoring systems.


The PF440IP 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 PF440IP 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.
