Ensure reliable and accurate level data with Hach’s FL900 redundant-level system.
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 Sigma 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.
Benefits
Redundant-Level Monitoring System
Often more than one level measurement is desired due to the application or site conditions. The Hach redundant-level system provides this capability and includes an FL902 flow logger, an AV9000 with a Hach submerged area velocity sensor, and an US9003 in-pipe ultrasonic level sensor. In this configuration, the pressure transducer in the submerged area velocity sensor and the in-pipe ultrasonic sensor measure level and either or both can be used to calculate flow. Redundancy is often desired to insure accurate level measurement in critical situations such as overflow monitoring or billing.
Plug-and-Play Sensors with FL900 Series Flow Loggers
Get started with the FL902 and create a flexible flow meter network using FL900 series loggers and plug-and-play flow sensors. Three velocity sensor technologies and two level sensor technologies are available along with both noncontact and submerged options. The FL902 used for the redundant-level system has two sensor ports and can be deployed for future projects with different sensor combinations to match the application.
Easy Installation Decreases Site Time and Increases Crew Effciency
For typical redundant-level monitoring applications, the submerged AV sensor and in-pipe ultrasonic sensor are installed on a single mounting band with the submerged AV sensor at the base of the pipe and the ultrasonic sensor at the crown of the pipe. For confidence in the installation, both sensors provide real time measurements and the in-pipe ultrasonic sensor includes a status LED that indicates proper installation and operation. With the time-saving features designed into the system, crews spend less time on site, increasing the effciency of flow monitoring crews.
The Power of Wireless
Eliminate risk by using wirelessly transmitted flow data to make smarter, real-time decisions regarding your collection system. With wireless-enabled models, you’ll receive alarms, via email or text, alerting you to any concerns at your monitoring sites. Plus, using FSDATA Online Data Manager, you’ll have secure 24/7 access to your flow data and wireless meter from the comfort of the internet. With FSDATA, site visits to collect flow data or to adjust meter settings are eliminated, decreasing maintenance costs. And you can set alarms and view sensor diagnostics remotely to maximize uptime. That’s the power of wireless.
