The McMenon FPD300 classical venturi tube is a robust, low pressure-loss device that is available in line sizes 50 to 1200 mm as standard, with larger sizes available upon request. The meter can measure a wide range of clean liquids and gases. Smaller sized units are machined from bar stock or forged bar; larger sizes are typically fabricated from rolled plate with forged flanges. For applications requiring very low pressure loss, McMenon offers a version that has a longer outlet cone with a shallower internal angle. This combination reduces the overall pressure loss.

The benefits of the McMenon FPD300 venturi tubes include the fact that they have no moving parts and are virtually maintenance-free, and that the performance of the device can be calculated from measurement of the key dimensions alone.

Suitable for a wide range of liquids, gases and steam, they are available in a wide range of materials to suit the process fluid and the working conditions, are suitable for horizontal or vertical pipelines, and are less affected by upstream disturbances than many other devices.
