Browse our line of SB mechatronic flow meters, a versatile solution for diverse applications requiring precise flow measurement. These advanced meters provide rapid response and reliability in environments where flow conditions frequently change, such as in machine tool coolant systems. 

The SB flow meters stand out for their sub-10-millisecond response time to coolant flow changes, ensuring cutting tools remain cool and efficient during intensive cutting cycles.

In the demanding settings of industrial furnaces, the stability and durability of flow measurement systems are paramount. SB mechatronic flow meters are designed to be unaffected by medium temperature changes, offering peace of mind in applications where loss of coolant flow could result in significant damage to components. Their innovative design, incorporating a spring-supported piston and magnetic sensor, allows for installation without specific inlet/outlet piping requirements, simplifying the setup process.

Enhanced with IO-Link technology, SB mechatronic flow meters deliver added value by transmitting multiple sensor values, including current flow rate, temperature, and switching status, all contributing to a comprehensive monitoring solution.

The meters come equipped with a non-return valve to prevent backflow and can be easily disassembled for cleaning, ensuring long-term accuracy and reliability. With their robust construction and advanced features, SB mechatronic flow meters are an ideal choice for ensuring optimal performance in critical flow applications.
