QCT liquid ultrasonic flow meter. Source: Flowtech. Flow Technology Inc. has introduced the QCT Series of liquid ultrasonic flow meters. Four meters are available ranging in size from 1/8 in. to 1 in.The QCT Series meters achieve an accuracy of +/- 0.5 percent of reading plus zero stability and repeatability of +/- 0.5 percent of full scale. The operating temperature range is –10° C to 80° C (14° F to 176° F). The meters output a 4 to 20 mA control signal.
The compact QCT Series has no moving parts and there is nothing in the flow stream that will cause an increase in pressure drop. High accuracy and repeatability are achieved through the 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-based products and oils, and the meter’s all-plastic construction suits it for many corrosive applications.
