Utilizing 1 MHz Acoustic Doppler technology and an integrated pressure transducer, this rugged sensor simultaneously measures flow velocity and level to calculate flow rates with exceptional accuracy and highly-consistent reliability. Also, the AV Sensor utilizes advanced hardware to automatically correct data measurements for temperature and velocity effects, ensuring precision in various conditions.

The AV Sensor is designed to be compatible with Hach flow loggers and AS950 samplers, making it a versatile tool for measuring flow rates in open channels.

The sensor’s cavity is filled with high-viscosity silicon oil, which reduces the buildup of sand, silt, and grit on the pressure transducer; it is available in both oil-filled and non-oil-filled versions, making this adaptable to different site conditions.

The non-oil-filled sensor is ideal for relatively clear sites or where the pipe may dry out, while the oil-filled version is best suited for environments with high levels of biological growth, grit, or silt.

Additionally, the module includes advanced diagnostics, such as capturing and displaying the Doppler spectra, allowing you to verify sensor performance on-site, ensuring everything is functioning correctly before you leave, which provides valuable peace of mind.

These thoughtful design options minimize maintenance requirements and prevent data loss, addressing common challenges in flow monitoring.
