Flow Technology Inc. (FTI) has introduced the QLF Series in-line ultrasonic flow meter, a compact, rugged, versatile, cost-effective solution for measuring ultra-low flow in a number of industries, such as chemical, oil & gas, industrial, and pharmaceutical. The QLF meter’s high accuracy and repeatability is achieved through the unique measurement section within the meter body where flow is conditioned and Delta T measured along its axis. The meter’s principle of operation measures the time difference of an ultrasonic wave traveling with and against the flowing medium. The time difference is directly proportional to the fluid’s flow rate. Temperature is measured via an RTD embedded into the flow meter body. The meter’s construction makes it the meter of choice for many high purity and corrosive fluids.
