Impeller SDI Series Flow Sensor

The Data Industrial SDI Series brass insert flow sensors from Badger Meter offers accurate 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 four-bladed impeller design is rugged, non-fouling, and does not require custom calibration.

Coupled with the proprietary patented digital detection circuit, the sensor measures flow from under 0.5 ft/sec (0.15 m/sec) to more than 20 ft/sec (6.1 m/sec) regardless of the conductivity or turbidity of the liquid.

The standard frequency output produces a low impedance square wave signal proportional to the flow rate that may be transmitted up to 2000 ft (610 m) without amplification. The
SDI Series includes:
• Single-direction powered insert with raw, scaled pulse and analog output
• Battery-powered insert with a local or remote display and scaled pulse output
