Product Overview
The TL-VX Series Vortex Flow Meter uses the Karman vortex street principle to measure volumetric flow rate of liquids, gases, and steam. With no moving parts, high reliability, and low maintenance requirements, it is widely used in steam measurement, compressed air, natural gas, and chemical liquid applications. Available in inline flanged, flange clamp, and insertion configurations.
