Mountain View, CA flow instrument maker founded 1978; WeldSaver monitors coolant flow and detects leaks in automotive robotic welding cells within 0.4 seconds.
Proteus Industries Inc., founded in 1978 by Jon Heiner in Mountain View, California, is a manufacturer of precision liquid flow switches, meters, sensors, and control systems for semiconductor equipment, automotive robotic welding, medical, and industrial applications. With over 45 years of flow management experience, the company develops products that measure, monitor, and control liquid flow rates and temperatures—enabling process control, equipment protection, and predictive maintenance for critical systems worldwide. The core product family includes the 8000 Series advanced flow meter/switches (available in standard, extreme-temperature XHT, and EMI/RFI-resistant EMR variants), the 800 Series, 100 Series flow switches, V7000 and PV6000 vortex flow meters, 6000 Series pulse-output flow meters, and Tofco FLC600/FLC700 flow controllers.
The company's most prominent robotics-specific product line is WeldSaver, a coolant control and leak detection system purpose-built for automotive robotic resistance spot-welding installations. WeldSaver 5 Passport and WeldSaver 6 Passport actively monitor coolant flow to weld guns and entire weld-cell cooling circuits, communicating status via standard industrial protocols (EtherNet/IP) to robot controllers and PLCs. The proprietary detection algorithm identifies leak conditions in under 0.4 seconds; on cap loss or circuit break, the system immediately signals the robot to halt welding and simultaneously closes an integrated shutoff valve.
The eVac Coolant Retraction Module, introduced with WeldSaver 6, actively evacuates the weld gun cooling circuit during cap changes to prevent coolant spills. Products support operating temperature ranges from -100°C to 200°C and include IP67/IP68-rated variants for wet environments. Proteus holds ISO 9001:2015 certification and is headquartered at 340 Pioneer Way, Mountain View, California.
