The TankWatch 4 Level Monitor System is designed to permit remote sensing of liquid levels in wastewater, gray
water or potable fresh water tanks. The TankWatch 4 utilizes three micro-float switches, which activate a four-
light panel. One is fixed and activates a full light when the liquid is within approximately 2-inches of the top
inside surface of the tank. The other two float switches are mounted on adjustable stems and can be positioned
to within 2-inches of the bottom of the tank. The stems are semi-flexible and are designed to flex with the
sloshing of the tank contents. A simple procedure allows one adjustable stem to sense when the tank is empty
and the other adjustable stem to sense when the tank is 1/4 or 1/2 full, depending on the application.
