ABSTRACT:
A digital liquid level measuring device determines the liquid level by reading a scale of a vertical series of horizontal binary coded numbers representing linear divisions. The measurement is direct rather than inferential and provides more accurate reading than existing methods. The digital measuring system does not suffer from the disadvantages of signal stability, drift, accuracy, calibration, error detection and size of range. The device has a fixed vertical scale, a float movable in a substantially vertical path maintaining a controlled distance from the fixed scale, a reading head on the float to read each of the horizontal binary coded numbers individually on the scale representing liquid level and a connection from the reading level to a display which provides an indication of liquid level.
