Utilising advanced DSP technology, the Micronics Portaflow PF220 Ultrasonic Liquid Flow Meter is the latest portable flow measurement and recording system to be added to the Micronics range of equipment. The 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.
Features:
- Light-weight, hand-held instrument with large, easy to read graphic display and switchable backlighting
- Flow range 0.1m/sec to 20m/sec bi-directional
- Useable with pipes ranging 13mm - 1000mm outside diameter (depending on model)
- Operator selectable language
- Simple to follow dual function keypad
- Simple ‘Quick Start’ set up procedure
- Continuous flow monitoring, with ‘Totalised’ option
- Variable Pulse output proportional to flowrate
- Variable 4-20mA, 0-20mA or 0-16mA output proportional to flowrate, with simple range calibration
- Rechargeable battery with up to 20hrs continuous battery operation depending on load
- Mains/battery operation with battery charge management
- Diagnostics
