Since the mid 1980's the Harwil Q-12 flow switch has been used by some of the largest companies in the Pool & Spa and fluid control industries. The Q-12 has several factory adjustable
parameters
that provide
the
flexibility
to meet the requirements of almost any
application. The Q-12
verifies
fluid flow, typically in
conjunction with another device. For example most of swimming pool
salt
chlorine generators use the Q-12 to verify
sufficient
flow before the generator is energized. In a spa or hot tub the Q-12 ensures
sufficient flow to prevent the water heater from a meltdown. In a chiller the Q-12 prevents the system
from freezing. At home the Q-12 turns on the water disinfection system when someone is getting a glass
of water.
