Global Water's WA150 Tilt Float Switch is an inexpensive, efficient and highly
reliable level detector for open vessels, sumps and ponds. The Tilt Float
Switch's molded rubber float has an integral three conductor cable and operates
on a micro-switch device that is located inside the rubber float on an
anti-vibration mount. The WA150 Tilt Float Switch includes an adjustable
cable weight, which allows it to be suspended from a convenient location above
the water rather than having to tie it off at your desired actuation
point. The Tilt Float Switch's rubber float is constructed of EPDM, a
synthetic rubber with rigid and durable characteristics for long service life
and resistance to heat, oxidation, ozone and aging due to weather. As a
non-polar elastomer, EPDM has good electrical resistivity, as well as
resistance to polar solvents such as water, acids, alkalies, phosphate esters
and many ketones and alcohols.
The WA150 Tilt Float Switch's basic operating principle is that as the fluid
level rises the rubber float will rise, causing the micro-switch to tilt and
generate a signal that can be used to operate a motor starter, open or close a
valve or actuate indicator alarms as required. The Tilt Float Switch's
3-lead cable allows operation on increasing level or decreasing level.
One lead is common, one is normally open (NO), the other is normally closed
Tilt Float Switch Installation Notes
There are no specific installation concerns for the WA150 Tilt Float
Switch. However, the Tilt Float Switch's lead cable should be supported
in an enclosed tank. Additionally, in an open tank, sump, or pond, it is
advantageous to clip the Tilt Float Switch's lead cable to the side, especially
if excessive turbulence is experienced (a nylon cable-tie is included).
To alleviate the effects of rapid switching conditions if such turbulence is
expected, it is recommended that a maintaining circuit be used to both
safeguard the Tilt Float Switch's micro-switch and cut out any chatter from the
starters of associated equipment, such as pumps.
An optional stabilizing weight and rubber "O" ring are included with the WA150
Tilt Float Switch. This may be installed at any point on the Tilt Float
Switch's lead cable.
