Venturi Flow Meters
Engineered Venturi Flow Meters for Accurate, Efficient Flow Measurement
PFS offers Venturi flow meters engineered for high accuracy and reliability, with low permanent pressure loss, and dependable performance across a wide range of flow conditions.
Designed for liquids, gases, steam, and other challenging line fluids, these meters give engineers flexible options for municipal, industrial, and specialized applications.
Lower Operating Cost Through Reduced Pressure Loss
Helps reduce energy loss and support more efficient system operation.
Reliable, Low-Maintenance Performance
No moving parts help minimize maintenance and support long-term performance.
Versatile for Clean & Challenging Process Media
Multiple designs available to fit different systems, media types, and installation needs.
