Product Overview
Thermal mass flow switches detect and monitor gas flow using heat transfer technology, ensuring safe and efficient operation. They provide accurate switching at preset flow thresholds, ideal for preventing damage to equipment or ensuring process integrity. Suitable for DN15–DN3000 pipes, they operate up to 100 bar and +180°C. Optional outputs include relay, transistor, and digital communication for integration with control systems. Compact and easy to install, these switches are widely used in energy management, gas supply monitoring, and industrial safety applications.
