A calibration system for a flow meter includes a flow simulator, the flow simulator including a receiver configured to receive flow meter transducer signals from a flow meter. A simulation subsystem is configured to create simulated transit time signal pulses, and to transmit the simulated transit time signal pulses to the flow meter at preselected time intervals. A calibration subsystem is configured to receive from the flow meter a transit time differential value generated by the flow meter based on the simulated transit time signal pulses and output a calibration factor to the flow meter.

System and method for field calibration of flow meters

A method includes measuring a radius of curvature at each of the plurality of positions of the outer peripheral surface of the predetermined section of the pipe is measured through the first device. A second device is detachably coupled to the plurality of positions along the outer peripheral surface of the predetermined section of the pipe. A wall thickness at each of the plurality of positions of the outer peripheral surface of the predetermined section of the pipe is measured through the second device. A cross-sectional area of the predetermined section of the pipe is measured based on a measurement data including the radius of curvature and wall thickness at each of the plurality of positions of the outer peripheral surface of the predetermined section of the pipe.

An automated method and system for calculating the transit time of a pulsed signal transmitted from a first ultrasonic transducer to a second ultrasonic transducer is provided. The method includes measuring the amplitude of the pulsed signal received at the second transducer from the first transducer; measuring the amplitude of any noise proximate to the received pulsed signal; and calculating the signal to noise ratio of the received pulsed signal and the noise, respectively. If the signal to noise ratio is above a predetermined threshold, a first technique is automatically implemented for calculating the transit time of the received pulsed signal. If the signal to noise ratio is less than the predetermined threshold, a second different technique is automatically implemented for calculating the transit time of the received pulsed signal.

An apparatus and method for measuring gas flow velocity through a high stack employs ultrasonic transducers. The transducers are placed on opposite ends of a diameter several hundred feet up, with a small vertical separation L between the transducers. Apparatus for measuring acoustic velocity in the stack gas over short path lengths is also included.
