The dBMACH3 and dB3 with double sun shields are specially designed for non-invasive flow measurement. Many flow metering devices require mounting in the bottom of a pipe or channel, which requires a shutdown of the operation for installation to take place. The dBMACH3 and dB3 with double sun shields are the ideal alternative open-channel flow sensors. The dBMACH3 is the first ultrasonic sensor to achieve a zero-effective blanking distance. The dB3 with double sun shields adds extra solar radiation protection to the sensor to ensure that the internal temperature can be utilized, ensuring flow measurement readings are as accurate and reliable as possible.
dBMACH3 High Accuracy Open Channel Flow Transducer
Featuring unique sun and submergence shields, the dBMACH3 is designed specifically for open channel flow applications. dBMACH3 is the first ultrasonic transducer with zero effective blanking distance beyond the nose cone, allowing it to be sited as little as a few millimeters from the high-flow level. One of the critical factors affecting the ultrasonic accuracy is the measurement distance, so by minimizing the distance, accuracy is maximized.
Operating at 125 kHz frequency the transducer provides high resolution and accuracy. Essential in open channel flow applications. The dBMACH3 can be used with the Ultra 4, 5, and TWIN when in open channel flow mode, or can be paired with the FlowCERT, all of which provide a typical accuracy of +/- 1 mm (0.039in). Resolution +/- 0.5 mm (0.019 in). Range 0 mm to 2.4 m (0 in to 7.9 ft).
dB3 with Double Sun Shields MCERTS Certified
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 the pair have been independently tested and 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.
