At times, depending on the difficulty of flow monitoring site applications or conditions, as well as in overflow monitoring or billing scenarios, more than one level measurement is desired to guarantee accuracy. That’s where the Hach Redundant-Level Monitoring System comes into play. This system combines a Hach FL900 Series Flow Logger with AV9000 Analyzer Module, a Hach Submerged AV Sensor, and a Hach US9003 In-Pipe Ultrasonic Sensor to create a highly accurate level monitoring solution. In this configuration, level is captured by both a pressure transducer in the Sub AV sensor and with ultrasonic technology in the in-pipe sensor, dramatically limiting your risk of missing data.
Hach has a complete portfolio of instruments and chemistries with support and services to help you get the right results.
