Hach Submerged Area Velocity Sensor
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.
Oil-filled Submerged AV sensor models are great solution for monitoring sites that are susceptible to fouling of the pressure transducer. The cavity is filled with high-viscosity silicon oil to reduce the collection of sand, silt and grit on the pressure transducer. Use the non-oil-filled cover plate model in sites where the pipe could run dry. Either way, we’ve thought about the little details that will reduce your maintenance or lost data hassles.
