Open Channel Ultrasonic Digital Doppler Flowmeter Sensor With Integrated Level Sensor. The BELUGA A/V is the newest digital ACOUSTIC area/velocity flow meter sensor for open channel flow measurements from FLOW-TRONIC. It is suitable for partially filled pipes and surcharged pipes without primary devices such as flumes or weirs.
This sensor combines advanced digital Doppler ultrasonic velocity sensing technology with most modern and powerful DSP processor technology, allowing real-time spectral analysis of the velocity distribution through the cross-sectional area. The sensor is designed for permanent or portable applications.
The BELUGA A/V is a powerful measuring system. With its integrated and replaceable pressure level sensor, it outputs flow directly without needing any other intermediate controller. All computations are made inside the sensor. The Smart Velocity feature can be activated for velocity and flow estimation when water level does not permit an efficient velocity reading (typically below 2 cm / 0.8 in). The RS485 Modbus RTU/ASCII allows an easy integration with a large variety of third-party loggers or controllers. For studies or measuring campaigns, it can be associated to the RTQ-IoT battery powered system with remote communication and remote configuration capabilities.
Optionally, the BELUGA A/V can be equipped with a 4-20 mA output for flow allowing an easy connection to any existing system. The side-mounted cable ensures efficient and space-saving mounting.
