About Rochester Sensors

Who We Are

Rochester Sensors is the industry leader of float level switch and liquid level sensor manufacturing. We excel in providing OEM’s high quality products, competitive pricing,

Rochester Sensors has adopted a company structure that we call the “Micro Factory”. Each micro factory team is responsible for customer service and product manufacturing for individual customers. Each team member takes personal responsibility for all aspects of each liquid level sensor order. Because each micro factory is dedicated to a small group of customers, they become intimate with the customers liquid level sensor preferences, insuring customers get what they need and want. Manufacturing personnel are trained to build fluid level sensors from beginning to end, insuring personal responsibility of their workmanship.

The micro factory structure creates an environment where people care about their workmanship (building the best float switches possible), customer satisfaction and meeting your personal liquid level sensor needs.
