Ultrasonic flowmeter with vibration-resistant operating mode

A method, comprising:

• providing an ultrasonic flowmeter (USM) including a meter body comprising a pipe section configured to flow a fluid including at least a first and a second ultrasonic transducer, and top-works including a housing and a printed circuit board (PCB) comprising electronics including a controller having associated memory coupled to the ultrasonic transducers through at least one of a transmitter and a receiver, and at least one of an accelerometer and an acoustic sensor for sensing a vibration on the pipe section for providing an output signal coupled to an input of the controller, the electronics communicatively coupled to the meter body, and the housing is mechanically coupled to the meter body by a mechanical joint;
• the controller:
• analyzing the output signal to identify at least one vibration frequency;
• comparing the vibration frequency to a predetermined sensitive frequency range for the USM, and
• when the vibration frequency is determined to be within the predetermined sensitive frequency range, implementing an anti-vibration operating mode comprising increasing a measurement time when measuring the flow of the fluid and adding additional data processing task(s), wherein the additional data processing task(s) comprises fast Fourier transform (FFT) processing followed by deconvolution. measuring the flow of the fluid and adding additional data processing task(s).
