2. What are the normal values of Q and T for ultrasonic flow meters?
The normal range of Q value for ultrasonic flow meters is: the minimum working threshold is ≥ 50, and the ideal working range is 600-900. The higher the value, the better the signal quality and measurement accuracy.
. 1. Normal range of Q value (signal quality indicator): • Minimum operating threshold: ≥ 50.0 (below which the flow meter cannot measure normally) • Ideal operating range: 600-900 (at this time, the signal-to-noise ratio is high, and the measurement data is stable and accurate) • Optimization direction: The higher the value, the better the signal quality. The Q value can be improved by adjusting the sensor installation position, improving the pipeline surface treatment, or optimizing the use of coupling agents. 2. T value (time measurement parameter) Currently, the specific normal range of T value for ultrasonic flow meters has not been clearly standardized in public information. The T-value is usually related to sound wave transmission time, time difference, or temperature compensation, but its specific meaning and threshold need to be determined according to the specifi
