The Signature® flow meter is designed for open channel flow monitoring applications. It supports flow measurement technologies including ultrasonic, bubbler, submerged ultrasonic area velocity, and non-contacting laser Doppler area velocity. The meter can calculate flow using standard open channel level-to-flow conversions, as well as user defined equations or level to flow data points, depending on the application need.
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.
