Hach US9000 Ultrasonic Sensor Series: Flow Monitoring & Level Alarming
The US9001B resourcefully takes the Down-Looking Ultrasonic Sensor and adds cable-straightening ballast to create a highly reliable SSO and CSO alarming solution when coupled with a Hach FL1500 Series Flow Logger and RS485 Modbus. And with highly accessible top-side mounting options that don’t require confined space entry, installation and maintenance is quick and simple, making this an extremely economical approach. So now you can capture data from more sites in your network without crushing your budget. Simply use the proven accuracy of the FLO-DAR® AV Sensor to monitor your critical primary sites, and then employ this more economical alarming option at secondary locations to smartly expand your system awareness and still live within your financial plan. Plus, you can also capture additional flow data using Manning’s equation.
More ultrasonic sensor options to solve more flow monitoring challenges
The Hach US9000 Ultrasonic Sensor Series provides you with a variety of independent level-measuring capabilities, giving you even more ways to ensure your flow data collection is consistent and accurate. These state-of-the-art non-contact sensors are excellent for both level measurement and alarming, or paired with a Submerged AV sensor for redundant level measurement.
