LFV200.XXSGHTPM

The SICK LFV200.XXSGHTPM is a compact, high-precision thermal mass flow sensor designed for continuous measurement of gas flow rates. It utilizes the thermodynamic principle (constant temperature anemometry) to directly measure mass flow, eliminating the need for temperature or pressure compensation. Its all-stainless-steel construction, high process compatibility, and robust design make it ideal for demanding industrial applications, including compressed air systems, process gas monitoring, and leak detection.
