1. Manufacturer of ultrasonic Doppler open channel flowmeter
2. What are the normal values of q and t for ultrasonic flowmeter
Normal range of Q value for ultrasonic flowmeter: minimum working threshold ≥ 50, ideal working range 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 specific equipment model and manufacturers technical manual. It is recommended to directly consult the equipment manual or contact the manufacturer for targeted parameter standards.
