Pocket-sized 4 in 1 Flow Meter The PU12 battery powered, shirt pocket sized Gas "Mass" Flow Meters and PUL12 Liquid Flow Meters measure and display Mass Flow (gas only), Volumetric Flow, Absolute Pressure, and Temperature. Using core technology, these sophisticated instruments are inherently linear and have an enormous turndown ratio (up to 1000:1). Standard ranges are from 500 micro-liters per minute full scale to 1000 liters per minute full scale for gases, 10 LPM for liquids. Different gas calibrations can be selected in the field by setting dip-switches on the back of the unit. An RS-232 interface streams data directly to laptop computers, so that all four of these parameters may be logged, or utilized, for real-time analysis.
