PRODUCT DETAILS
This insertion thermal mass flow meter enables precise measurement of mass flow rate with direct output of standardized volume flow rate, delivering high accuracy across both small and large flow ranges. The thermal mass flow principle automatically compensates for pressure and temperature, ensuring reliable and consistent measurements without external correction.
The sensor is designed for easy installation and removal. The integrated measuring section can remain installed in the pipeline during sensor removal for cleaning or recalibration and can be safely closed using a sealing cap, minimizing downtime.
With no moving parts, the flow meter requires minimal maintenance and offers long-term operational stability. Its design ensures an extremely low pressure loss due to negligible blockage of the pipe diameter.
The device is suitable for compressed air and non-corrosive gases such as nitrogen, oxygen, argon, and helium, making it ideal for a wide range of industrial gas applications.
