ELBOW FLOW METERS Available in carbon steel, stainless steel, aluminum and other alloys. Designed for flow measurement in "tight pipe conditions" and where no additional head loss is permitted.

ABOUT THE ELBOW FLOW METER

Ideal as a "no headloss" meter in existing piping where elbows are present . Non-intrusive design ideal for "pigged" piping. As fluid passes through a pipe elbow, the pressure at the outside radius of the elbow increases due to centrifugal force. Pressure taps located at the outside and inside of the elbow at 22.5 or 45 degrees will generate a reproducible measurement. Taps located at angles greater then 45 degrees are not recommended as flow separation may cause erratic readings.

Generally, units are individually flow carbrated prior to shipment.
