ARJAY Engineering

Arjay Engineering is a Canadian manufacturer specializing in industrial level monitoring, oil-in-water analysis, liquid interface detection and process control instrumentation. Established in 1983, Arjay develops advanced measurement technologies designed to improve process reliability, protect equipment and support environmental monitoring across demanding industrial applications. Its radio frequency (RF) capacitance-based monitoring systems provide reliable measurement of liquids, solids and material interfaces while minimizing maintenance requirements.

Arjay's product portfolio includes continuous level transmitters, point level switches, oil/water separator monitors, oil-in-water analyzers, tank leak alarms and process protection instruments. Specialized technologies such as HydroSense oil-in-water analyzers, oil/water interface transmitters and emulsion profilers help facilities monitor hydrocarbon concentrations, identify liquid interfaces and optimize separation processes. Additional solutions for dry pump protection, foam control and plugged chute detection help reduce equipment damage, minimize process interruptions and improve operational efficiency.
