Flowmeters with Photosensor (for Alarm Switches)

MODEL RK1812/RK1814 series

These are enhanced models of the KOFLOC High Precision Flowmeters RK1200 and RK1400, respectively, by attaching photoswitch sensors for detection of float position and issuance of alarm signals.

Features

Red LEDs are used to visualize projected light spots. Stable and running modes of flows can be checked by pilot lamps.
