Series FTS Thermal Flow Switch is especially designed, for all
types of cooling systems, as a reliable alternative to failure prone mechanical
flow switches. The Thermal Flow Switch continually samples the
temperature of the coolant and adjusts the low flow setpoint automatically,
providing a solid state switch should the coolant flow rate fall
below the setpoint value. In addition, the Thermal Flow Switch will
provide an alarm output should the coolant temperature rise above
acceptable levels. You have double protection with the FTS.
