Flange Mount Pneumatic (Model 31C2)

The Ruelco Flex Level Model 31C2 is a pneumatic liquid level switch. It incorporates a slip ring mounting feature, providing it with the highest degree of sealing integrity. The sensor operates a pneumatic valve when the liquid in a tank or pressure vessel reaches a predetermined level. The level switch can be configured as a low or high level switch, with either two or three way operation.

  • 316 stainless steel construction (models to N.A.C.E. MR0175 available).
  • Design has no deep cavities or recesses exposed to the process fluids for debris accumulation and is excellent for dirty fluid applications.
  • Uses a patented pivot seal mechanism to transmit liquid buoyancy to the valve operation mechanism with the pivot completely isolated from the process fluid.
  • Mode of operation (‘HI’ or ‘LO’) is easily changed and no re-calibration is required.
  • Level adjustments cannot be easily tampered with after installation, making this switch well suited for critical applications.
  • 0.6 specific gravity operation.
