Description

PSF20x is a programmable flow transmitter/monitor 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 converting flow rate into a standard linear output signal. An RS232 serial interface is also available. The material types used (PVDF, Vectra®, Viton®, EPDM, etc.) have a good thermal (up to 90 °C) resistance. A special variant with increased chemical resistance also extends the transmitter application. Other ranges except the standard 0.5…20 l/min flow range are available on request. PSF20x is equipped with a keyboard and a local 3-digit LED display for easy programming and flow monitoring and can be used both as a flow meter and transmitter suitable for water treatment and other applications.
