Micronics Portaflow PF330 Ultrasonic Liquid Flow Meter

Utilizing advanced DSP technology, the Micronics Portaflow PF330 Ultrasonic Liquid Flow Meter is the latest portable flow measurement and recording system to be added to the Micronics range of equipment. The PF330 can display instantaneous fluid flow rates or velocity, together with totalised values. It also incorporates a data logger that can record up to 98k events 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 PF330 to enable it to interface with a range of external control devices such as those found in building management or site monitoring systems.
