Standard and custom sensors for various process control applications

Our ultrasonic sensors measure liquid level despite variations in transparency, viscosity, color, or dielectric. These solutions include air bubble detection for medical pumps; point and continuous level sensors for the semiconductor and high purity markets; and point level sensors for a variety of process control applications. We offer high accuracy, high frequency, short range continuous measurement ultrasonic sensors through air for process control. We manufacture standard and custom products that provide a system without moving parts, adjustments, or maintenance.
