Profile Home


Proteus Industries is dedicated to developing high quality and innovative flow management products and providing consistent customer satisfaction.

Proteus Industries was founded by Jon Heiner in 1978. Starting his career in the semiconductor equipment industry and recognizing the need for reliable flow switch, he developed Proteus' first flow switch, model 100B, and acquired his first customer, Varian.

Starting his flow technology venture in his parents' basement, he began to expand and started developing, manufacturing, and marketing a range of rugged yet sensitive liquid flow switches, meters, and sensors.

Since that time, Proteus Industries has developed into the leader in flow measurement innovation and manufactures a complete line of flow management devices at the highest specifications in the industry.

Proteus offers a full line of instruments and control solutions for the semiconductor and fab equipment industry. Today, our products are used in virtually every semiconductor fab around the world.

Our WeldSaver™ is a leading cap loss detector and coolant flow controller for robotic welding applications, and our leak detection system provides the ultimate protection against catastrophic leaks for mission-critical equipment. Our sensors are used around the world to protect thousands of induction furnaces, welding torches, high-power lasers, plasma cutting systems, and semiconductor processing systems.

Proteus is also the exclusive U.S. distributor of Tofco flow management products, including flow meters for ultrapure liquids, flow controllers, and the Tofpine Manifold System. We pride ourselves on our ability to quickly provide custom engineering, including multi-sensor panels and manifold assemblies.
