ABSTRACT:
A method of detecting an effluent level in an aircraft lavatory holding tank and a device for practicing the method. The device uses electrodynamic forces of different values generated by an electro-impulse solenoid to determine whether a detector is contaminated, to dislodge contaminants, and to measure the fluid level in the holding tank when the detector is clean enough to produce an accurate reading.
