Micronics PF330 Portable Ultrasonic Flowmeter

The Micronics PF330 Portable Ultrasonic Flowmeter can display instantaneous fluid flow rates or velocity, together with totalised values. It also incorporates a data logger that can record up to 200,000 datapoints which can be output directly to a PC or printer or stored in the instrument’s memory for downloading at a later time.


Micronics PF330 has been discontinued in 2021, replaced with the new Micronics PF333 Portable Ultrasonic Flowmeter which includes all the same functionality with the added option of a heat meter for boiler efficiency.  Please contact Fluidic for help with product selection.

A variable current or pulse output, proportional to the detected flow rate, is also produced by the PF330 to enable it to interface with a range of external control devices such as those found in building management or site monitoring systems.

The PF330 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 PF330 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.
