Designed specifically for harsh environments, the S452 heavy duty industry flow sensor is ideal for measuring gas flow and consumption in heavy industrial and hazardous applications.

Measure volumetric standard flow over a wide measuring range.

The SUTO flow sensor S452 is based on the thermal mass flow principle. It measure volumetric standard flow over a wide measuring range. The result is pressure and temperature independent.

Suitable for the pharmaceutical and food industry.

S452 is designed specifically for harsh environments. The NEMA 4X enclosure with IP67 allows all-weather applications, All parts which come into contact with the measurement medium are made of stainless steel 316L. This allows applications in the pharmaceutical and food industry, but also the measurement of corrosive and contaminated gas. Installations in explosive environment can be done through the optional ATEX approval. Various gases can be measured such as air, oxygen, argon, carbondioxyde, natural gas, hydrogen, methane, etc. Basically any gas mixture can be measured as long the mixing ratio and its components are known and constant.

It is designed to fit your needs in compressed air flow measurements.

Suto iTec

We have partnered with Suto iTec to provide compressed air & gas measurement technology to Australia.

SUTO iTEC was born from an idea that compressed air and gas systems need improvement, that end-users were being starved of technology required to manage these systems and that the level of wasted energy needed to be brought under control. Since its inception in 2005, SUTO has grown to be one of the world leaders in compressed air and gas measurement technology and is the market leader in compressed air purity monitoring equipment.
