Features
The thermal mass flow sensor provides direct output of standard
volume flow by accurately measuring mass flow.
It offers high accuracy for both small and high flow rates, making
it suitable for a wide range of applications.
The sensor incorporates pressure and temperature compensation
through the thermal mass flow principle, ensuring precise
measurements even in varying conditions.
Installation of the sensor is quick and easy, thanks to its
compatibility with a ½" ball valve. Its design features no moving
parts, resulting in low maintenance requirements. Additionally, the
sensor has minimal pressure drop due to its unobstructed diameter,
ensuring efficient flow without significant energy loss.
The thermal mass flow sensor is suitable for measuring compressed
air and non-corrosive gases, including nitrogen, oxygen, argon,
helium, and more.
Its versatility and robust performance make it a reliable choice
for various industries and applications requiring accurate and
dependable flow measurement.
