PSF21x, Programmable Flow Meter/Switch with Pulse O/P
3-Digit programmable flow alarm with display capable of switching from 0.5 to 20 l/min. NPN alarm output and TTL Pulse Output.
PSF21x is a programmable flow controller designed for use with low-viscose clear or translucent liquids, transmitting IR light. The operating principle is based on the liquid volume measurement through light-weight rotor, IR sensor, and sophisticated electronics for measurement and control. The material types used (PVDF, Vectra®, Viton®, EPDM, etc.) have a good thermal (up to 90 °C) resistance.
The PSF21x is equipped with a local 3-digit LED display and a hidden key for easy programming and flow monitoring.
This model has pulse an NPN alarm outputs. The alarm output can be programmed to activate when either of the programmable alarm limits is reached. The pulse output provides TTL pulses for flow measurement with a sensitivity of 6000 pulses per litre. PSF21x can be used as a flow meter, ON/OFF flow controller, or alarm unit suitable for water treatment and other applications.
