PRODUCT DETAILS
This insertion thermal mass flow meter provides direct measurement of mass flow with output of standardized volume flow, delivering high accuracy across both low and high flow ranges. The thermal mass flow principle ensures automatic pressure and temperature compensation, eliminating the need for external correction.
Installation is quick and straightforward via a ½" ball valve, allowing mounting under pressure without system shutdown. With no moving parts, the sensor requires minimal maintenance and offers long-term operational reliability. The design ensures an extremely low pressure drop due to negligible blockage of the pipe diameter.
The meter is suitable for compressed air and non-corrosive gases such as nitrogen, oxygen, argon, and helium, and supports a wide range of pipe diameters.
