protection into your equipment. By principle of operation,
the rotor cannot be deceived into indicating a positive
flow situation when no flow actually exists. Once
set to a desired actuation point, RotorFlow
will switch to a “no-flow” condition should
the rotor stop for any reason.
Typical Applications
Protect expensive electronic
equipment from coolant flow
