Water level monitoring float system

Abstract From the Canadian patent

The invention provides an improved float and float system for use in the monitoring of fluid levels, particularly in small diameter wells by way of a cable and float system. The float system includes a number of centralizers which hold the float cable near the center of the well casing and thus reduce the friction of the cable on the casing walls. The addition of weights on the float cable, either or both below the float and between the float and the top of the well casing, can improve the accuracy and operation of the system even further. A truncated cone-shaped float is provided with a number of fins , displaced evenly around the circumference of the float.
