The QCT_PA12 Series of in-line liquid ultrasonic flow meters are intended for use in low-viscosity liquid applications requiring excellent accuracy and reliability at an economical price point.
The series is a cost-effect and versatile solution for measuring low-viscosity liquids in a wide range of industries, such as chemical, food & beverage, pharmaceutical, plastics, power generation, pulp & paper, semiconductor, and steel.
The meters’ construction and Nylon-12 (PA12) material make them the meters of choice for many high purity and corrosive liquids. Typical applications include water treatment for boilers and cooling towers, clean-in-place (CIP) systems, mechanical seal flushing/cooling, process water, cooling loops, reverse osmosis (RO) systems, small-line injection systems, and larger DI water distribution systems and high-purity filtration systems.
High accuracy and repeatability are achieved through the unique measurement section within the QCT_PA12 Series 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 traveling with and against the flowing medium. The time difference is directionally proportional to the fluid’s flow rate.
The QCT_PA12 Series flow meters have non-wetted sensors, no moving parts, and there is nothing in the flow stream that will cause an obstruction to the flow path. The meter is available in sizes 1/8 to 2 in., 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 250 GPM flow range, 14° to 176°F (-10° to 80°C) temperature range, and analog, scaled frequency, and Modbus RTU outputs.
