GAUGE FOR MEASURING LIQUID LEVELS

摘要

An apparatus for measuring liquid level in a container. A flexible measurement scale (12), attached at one end (16) to a weight (14) for retainment at the bottom (18) of a container (20), and at the opposite end (22) to a receiver (26) at the top of the container (20). Float (32) has a configuration and density to place a portion (44) of the float (32) below the level (46) of the liquid and a portion (48) above the liquid level (46). Portion (48) above the liquid level (46), contains transmitter for applying energy to one side of the scale (12), and detectors for detecting energy transmitted through the scale (12) and converting it to a signal indicative of a particular code on the scale (12), indicative of the liquid level (46). Float (32) has a link transmitter (30) for sending the detected signals to the receiver (28) at the top (24) of the container (20). Receiver (28) contains a display read-out (34), or functions as a transceiver sending signals to a remote display unit (96).
