Mass flow meters for gases

A gas flow sensor (alternatively called a flow meter) is an instrument that measures the gas flow rate in a tube. An accurate gas flow measurement ensures a safe, efficient and environmentally compliant operation in all applications and industries.

With a long experience in designing innovative mass flow solutions for medical and industrial equipment, our sensors assist with a quality measurement of the flow rate. We provide high-end products, with cutting edge technology and high-performance capabilities to ensure the accurate measurement of the exact dosing of gases (flow rate) in a variety of processes and applications.

For that reason, ES Systems has developed two distinct types of resistive MEMS flow meters, inline and insertion, that can be used in any application that requires high performance and reliability. Their revolutionary design combined with exceptional technical specifications, outstanding reliability, and competitive prices, makes them one of the best flow measurement solutions in the market.

Frequently asked questions

Our gas flow sensors measurement principle is MEMS calorimetric or thermal mass. In simple terms, as the measured gas passes over the sensing element, heat is transferred to it. By accurately measuring the heat transferred, the gas flow is calculated. Due to the measurement principle as well as our innovative electronics design, the gas flow sensors can provide very accurate and reliable measurements.
