Flow Measurement and Controls (Badger Meter)

SDI Series Flow Sensor

The SDI Series flow sensor offers unparalleled performance for liquid flow measurement in closed pipe systems in an easy-to-install economical package. Impeller sensors offer a quick response to changes in flow rate and are well suited to flow control and batch-type applications in addition to flow monitoring. The new four-bladed impeller design is rugged, non-fouling and does not require custom calibration.
