dB3 with double sun shields
Pulsar dB3 with double sun sheilds – Open Channel Flow

When combined with the Ultra 4 Controller, the dB3 with double sun shields has achieved MCERTS Class 1 Certification with 0.136% combined accuracy. This means that the pair have been independently tested and have performed well under rigorous conditions. Utilities across the globe can now be confident that their flow measurement is of the highest possible accuracy by using MCERTS certified equipment.
The dB3 with double sun shields is specifically designed for open channel flow applications. One of the critical conditions of ultrasonic measurement is the measurement distance, therefore, its short measurement range of 3 m and maximized accuracy at zero blanking meet this requirement. The double sun shields of the dB3 help to protect the transducer from solar radiation and combats ambient temperature changes that could ultimately affect the flow and level readings, ensuring the accuracy in measurements.
