Due to fluid properties, flow patterns, external factors (temperature, pressure, etc.) measurement shows a dynamical characteristic. Therefore, calibration is an indispensable process in order to ensure the standards of flow metering. Ultrasonic flow meters, which are ameliorated the readings over time, are promising devices to minimize the flow measurements error. In this paper, the calibration procedure of a specific ultrasonic water flow meter is discussed, and then a wireless system is proposed to carry out fine calibration. According to the results, piecewise linear least squares approach supplies the best performance at overall volumetric flow rates accompanying with wireless fine calibration system based on RF communication
