Waste and Potable Water Systems

AMETEK SFMS designs level and quantity sensing solutions for aircraft potable-water tanks and lavatory-waste systems. Capacitive technology provides measurement without relying on mechanical movement, supporting compact installations and reliable operation in tanks exposed to vibration, fluid contamination, temperature change, and repeated service cycles.

Potable-water sensors can measure water height and provide a DC output proportional to the level for connection to the aircraft water-system controller. Lavatory-waste sensors use capacitive sensing with integrated signal processing and can provide a tank-full output when waste reaches the sensing point. Sensor length, mounting, output, connector, and housing can be tailored to the tank and aircraft architecture.

• Continuous water-level measurement and discrete waste-full detection
• Capacitive sensing suitable for applications where moving parts are undesirable
• Integrated electronics options for conditioned outputs

• Custom mounting and mechanical configurations for tank geometry

   

AMETEK SFMS draws on broader aircraft fluid-level expertise to address material compatibility, calibration, wiring, sealing, environmental exposure, service access, and controller integration.
