For users with a large number of fixed ultrasonic flow meters installed on-site over a wide area, a portable ultrasonic flow meter of the same type can be provided for calibrating the instruments in the field.
1. One-time calibration is possible, meaning each newly installed ultrasonic flow meter is calibrated during installation and commissioning to ensure proper location, installation, and accurate measurement.
2. When a sudden change in flow rate occurs in an online ultrasonic flow meter, the portable ultrasonic flow meter can be used for timely calibration to determine the cause of the change, clarifying whether it is an instrument malfunction or a genuine change in flow rate. This allows for monitoring the flow meter's usage status, enabling problem detection and subsequent maintenance.
