In-line flowmeters for low-viscosity fluids
The QCT Series of inline ultrasonic flowmeters (photo) is a compact, versatile, cost-effective solution for measuring low-viscosity liquids in the chemical process industries (CPI). The meter’s construction makes it suitable for many high-purity and corrosive fluids. 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. High accuracy and repeatability are achieved through the unique measurement section within the QCT Series meter where flow is conditioned and temperature differential measured along the meter’s axis. The QCT has no moving parts or non-wetted sensors, and 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 in., and is accurate to±0.5% of reading, plus zero stability and repeatability is±0.2% over 10:1 calibration range. It has a flow range of 0.035 to 70 gal/min, a temperature range of –10 to 80°C and analog, scaled frequency and Modbus RTU outputs. — Flow Technology, Inc., Tempe, Ariz.
