Badger Meter Flow Sensor with Integral Flow Transmitter SDI Series

Badger Meter Flow Sensor with Integral Flow Transmitter

 

The SDI Series flow sensor with integrated transmitter is available in either brass or stainless steel. A popular choice in Building Automation Systems, BAS, and HVAC applications, these hot tap stainless steel flowmeters include isolation valve and mounting hardware. These enable flow meter installation and removal while the piping system is pressurized; system shutdown is unnecessary. Hot tap stainless steel models are also available for bidirectional flow measurement. The impeller is rugged and non-fouling and requires no custom calibration. The SDI Series is available with a frequency output, analog output, and scaled-pulse output and the display is optional; programming is done using the A301-20 Programming Kit. Stainless steel models are available with a PEEK (polyetheretherketone) tip for high (up to 300 °F) fluid temperatures.
