General description
The TYCO Model TF Vane Type Waterflow Switch is
designed to detect a waterflow condition in a wet sprinkler
system.
The switch assembly contains single-pole, double-throw
(SPDT) contacts, and an adjustable pneumatic vane. The
switch activates when a flow rate exceeding the flow
sensitivity of the switch occurs. The flow condition must
exist for a longer period than the retard delay setting of
the vane for the switch to operate.
