Abstract

A movable float mechanism coacts with a stationary electrical measuring device to generate electrical signals representative of the liquid level in a tank. The float mechanism is comprised of a bulbous base section and an elongated stem section. A plurality of indicative zones (contact positions) are marked along the stem section of the float. Each indicative zone corresponds to a desired liquid level. For example, the full contact position indicative zone represents the position of the float relative to the liquid when the tank is full. Similarly, the half empty contact position indicates when the tank is half full and the empty contact position indicates when the tank is empty. An adjustable tube is fitted in a base support member and around the stem portion of the float mechanism.

Liquid Monitor

A movable float mechanism coacts with a stationary electrical measuring device to generate electrical signals representative of the liquid level in a tank. The float mechanism is comprised of a bulbous base section and an elongated stem section. A plurality of indicative zones (contact positions) are marked along the stem section of the float. Each indicative zone corresponds to a desired liquid level. For example, the full contact position indicative zone represents the position of the float relative to the liquid when the tank is full. Similarly, the half empty contact position indicates when the tank is half full and the empty contact position indicates when the tank is empty. An adjustable tube is fitted in a base support member and around the stem portion of the float mechanism. The tube carries a common electrical contact wire and electrical wires A, B and C. Each of the wires A, B and C has one of its ends disposed to coact with one of the contact positions. The other end is connected to one of the circuits A1, B2 and C3 (Fig. 2), respectively. In operation, the bulbous portion of the float member is placed in the tank containing the liquid. As the level of the liquid changes, the float mechanism will move in a direction substantially perpendicular to the level of the liquid. As the float mechanism moves relative to the fixed adjustable tube, the common contact wire moves against the external surface of the tube. Likewise, as the level of th...
