Kofloc Model RK1930/RK1935 Compact Reed Switch Flow Meter for Alarm Switches

Description

The Kofloc Model RK1930/RK1935 Compact Reed Switch Flow Meter is the perfect solution for modern OEM equipment that demands smaller components without compromising on safety features. This model uses a specialized magnetic float within a tapered glass tube. As the float reaches the position of the externally mounted reed switch, the magnetic field triggers the contact, sending an “All OK” or “Alarm” signal to your PLC or control panel.

The series offers two primary configurations:

RK1930: A streamlined model without a control valve, used for dedicated monitoring and alarm signaling.
RK1935: Features an integrated needle valve at the bottom (inlet), allowing for precise flow adjustment and alarm setting in one miniature unit.

The reed switch is passive, meaning it does not require power to operate the sensor itself, and it is completely unaffected by ambient light. This makes the Kofloc Model RK1930/RK1935 Compact Reed Switch Flow Meter highly reliable in various industrial lighting conditions. The switch can be easily slid up or down the tube to adjust the alarm set-point, providing maximum flexibility for different process requirements.
