Ultrasonic Doppler flowmeter Beluga designed for contact-type flow measurement in open channels and partially filled pipes
Utilizes advanced DSP technology and digital Doppler ultrasonics for precise transit time fluid processing and flow rate calculation, extending it to cross-sectional area and considering the height parameter allows accurate flow measurement.
The sensor, along with a monitoring display (fixed or portable) and an ultrasonic height sensor, transforms into a complete flowmeter that can display, record, and store parameters such as velocity, level, instantaneous flow, etc., periodically.
