Flow Switches
High-accuracy flow sensors for dependable fluid and gas monitoring
What is the purpose of flow sensors?
Industrial installations rely on flow switches to accurately detect and control the flow of liquids and gases within pneumatic and hydraulic networks. By offering precise flow rates measurement, these devices support optimal machine performance and reduce the risk of failures caused by inconsistent flow.
Across industries such as machine tooling, industrial maintenance, industrial communication, and energy efficiency, flow measurement plays a crucial role. Precise monitoring of gas and liquid flow helps optimise operations, ensure safer processes, and reduce overall energy consumption.
Versatile flow sensors and switches from SMC for a wide range of uses
Our offering at SMC includes a diverse selection of flow sensors and switches designed to adapt to industrial challenges. Among them are:
