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.
