Wyatt PMT-IF Lo-Loss Flow Tube Insert Element

The Wyatt Engineering PMT-IF Lo-Loss Flow Tube Insert Element (Model/Part Number PMT-IF) is an industrial venturi-style differential flow measurement primary element designed for accurate low-pressure-loss flow monitoring in liquid and gas process systems; installed between adjacent pipe flanges, this insert-type fabricated venturi provides permanent flow monitoring for pipelines carrying clean liquids and gases. Commonly used in water treatment, power generation, chemical processing, HVAC, steam systems, and other process-control applications where precise flow measurement with minimal energy loss is required. Key specifications include accuracy of ±0.25% with flow calibration and ±1.00% without calibration, lower pressure loss than orifice plates and conventional venturis, and up to 97.5% differential pressure recovery on high beta ratio designs; temperature range from -325°F to +1200°F depending on materials, and a pressure capability of 4000–6000 PSIG. Construction is fabricated from virtually any alloy or material depending on application, and the unit supports horizontal or vertical full-pipe flow installations with clean liquids and gases of low solids content; common replacements include Emerson Daniel Venturi Flow Tubes, ABB Venturi Flow Elements, and McCrometer V-Cone Flow Meters.
