The Signature flow meter is designed for open channel flow monitoring applications. It supports flow measurement technologies including bubbler, non-contact laser area velocity, submerged Doppler ultrasonic area velocity, and ultrasonic. The meter can calculate flow using standard open channel level-to-flow and area velocity conversions, as well as user-defined equations, level to area data points, or level to flow data points, depending on the application need. The Signature flow meter has unique features to verify data integrity. It logs key events such as changes in calibration and power outages to validate data accuracy. Data can be easily reviewed to detect any type of data alteration. With multiple smart interface options and multi-parameter logging (such as pH), the Signature flow meter provides a common platform for control action, reporting, and communication. Multiple flow technologies are available so you can select the best flow technology for the measurement site and channel conditions. Available technologies are: bubbler, ultrasonic, continuous wave area velocity, and non-contacting LaserFlow™ velocity.
