S.A.F.E.

S-A-F-EAcoustic filter specifically designed to reduce the effects of noise on ultrasonic meters

  • Reduces control valve noise up to 45 dB
  • Works with any gas ultrasonic meter
  • Ideal for retrofit installations
  • Simple flange-mounted installation
  • Rugged design
  • Line sizes 4” – 24+”

Current Research indicates that control valves should be placed downstream of Gas Multi-Path Ultrasonic Meters (MUSMs) to ensure that the acoustic noise generated by the valve does not “scramble” the acoustic signal of the ultrasonic meter.

Various techniques are used by the MUSM manufacturers to minimize the impact of ultrasonic noise generated by control valves, however the near elimination of noise by the S.A.F.E.® offers significant advantages to the user.

The S.A.F.E.® is a proven acoustic filter that will enable the user to maximize the operating range of the MUSM and to simplify the meter station design process.
