Flow Technology QCT Series inline ultrasonic flow meters

Flow Technology has introduced the QCT Series of inline ultrasonic flow meters for use in low-viscosity liquid applications. The series is a compact and versatile solution for measuring low-viscosity liquids in a range of industries, including food and beverage.

Available in a range of sizes and features to meet a variety of application requirements, the meter can measure the flow of any clean, low-viscosity liquid.

High accuracy and repeatability are achieved through the unique measurement section within the meter where flow is conditioned and Delta T measured along the meter’s axis. The meter bases its operation on measuring the time difference of an ultrasonic wave travelling with and against the flowing medium. The time difference is directionally proportional to the fluid’s flow rate.

With no moving parts, non-wetted sensors, there is nothing in the flow stream that will cause an obstruction to the flow path. The meter is available in sizes of 1/8 to 1″, accurate to ±0.5% of reading plus zero stability and repeatability is ±0.2% over 10:1 calibration range. It has a 0.035 to 70 GPM flow range, -10 to 80°C temperature range, and analog, scaled frequency and Modbus RTU outputs.

Typical applications include water treatment for boilers and cooling towers, clean-in-place (CIP) systems, mechanical seal flushing/cooling, high purity water systems, process water, cooling loops, reverse osmosis (RO) systems and small line injection systems.
