By pairing Hach’s Submerged AV Sensor with our state-of-the-art Hach AV9000 Analyzer Module, you create a powerful Hach Submerged Area Velocity Meter (FL900AV) which provides “cleaner,” more precise data than ever before.
Our Submerged AV Sensor is a robust, 1 MHz Acoustic Doppler velocity sensor designed to measure wastewater flow with improved accuracy and reliability. This tried-and-true sensor also uses a pressure transducer to measure flow level and incorporates advanced technologies to ensure precision, including automatically correcting for temperature and velocity effects on measurements. With advanced signal processing and filtering options, the AV9000 Analyzer Module expands the applicability of the sensor into more difficult applications. Plus, advanced analyzer diagnostics, including capture and display of the Doppler spectra, allow you to verify that the sensor is working properly even before you leave the site, giving you peace of mind.
