Description

Obtain reliable measurements even in explosive environments.

The SUTO S450 and S452 flow sensors use the thermal mass flow measurement principle, also providing standard volumetric flow. Their measurements are independent of gas pressure and temperature, ensuring accurate results under any condition.

Thanks to their wide measurement range, the S450 and S452 are ideal for detecting everything from small leaks of natural gas or compressed air to the normal consumption of pneumatic installations, helping monitor compressor performance and optimize energy efficiency in industrial settings.

Applications

All parts in contact with the measuring medium are made of 316L stainless steel, ensuring resistance and durability even with corrosive gases.

The sensor features two calibration curves, enabling high-precision measurements for two different gases.

Compatible with multiple communication protocols: 2 analog outputs (4–20 mA), pulse output, Modbus, HART, and M-Bus, facilitating integration into existing industrial systems.

Ideal for flow monitoring in explosive or highly demanding environments, ensuring safety and reliability in critical applications.

Advantages

Compatible with a wide range of pipe sizes and connection types (threaded, flanged, DN15–DN80; other sizes available upon request).

Integrated display showing flow, consumption, medium temperature, and diagnostic results, allowing fast and efficient monitoring.

Robust metal housing with IP67 design, ideal for outdoor use and harsh industrial environments.

Easy installation and minimal maintenance, reducing downtime and operational costs.
