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 posi-
tioned 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.
