QCT Series In-Line Ultrasonic Flow Meters for Low Viscosity Liquid Applications

Source: FTI Flow Technology, Inc.

The compact QCT Series has no moving parts and there is nothing in the flow stream that will cause an increase in pressure drop; this results in a very rugged, reliable and accurate flow meter. High accuracy & repeatability is achieved through the unique measurement section within the flow meter where the flow is conditioned and delta T is measured along the axis of the flow meter. The small footprint, lightweight device is ideal for low viscosity liquid applications including water, water-based products, oils, and its all plastic construction makes it the meter of choice for many corrosive fluids.
