Gemini™ Magnetic Level Indicator

Gemini's twin chamber design is unique to the magnetic level gauge industry. Over 18 configuration styles are available with Gemini, and though not available in plastics, it may be produced in the same metal material selections as Atlas. Gemini's second chamber facilitates the installation of the Eclipse Guided Wave Radar transmitter, thus providing a totally redundant measurement system. With standard magnetic indicators with side clamp-on transmitters, the float represents a single point of indication. If the float should become damaged due to violent process conditions, the signal from the analog transmitter is lost. With Gemini's dual chamber design, Eclipse will continue to measure the liquid level accurately, repeatedly and reliably, as it is not dependent on interaction with the float.

Gemini's magnetic indicator chamber can be equipped with switches, transmitters, blankets or heat tracing, while the secondary chamber houses the electronic measurement instrument.

Measurement Principle

Change in the process tank level corresponds to change in the Gemini chamber. The float within the chamber actuates flags or a shuttle for visual indication. The instrument mounted within the second chamber also reacts according to the level change.

Technology of the Gemini™ Magnetic Level Indicators

The appeal of magnetic level indicators is total isolation of the process within a sealed piping column. Elimination of leaking seals, clouded glasses, broken glass tubing, plus easy access cleaning and adaptation to a variety of mounting styles and process connections. Availability of switches and transmitters adds to their desirability by providing a much less expensive system than a buildup of sight glasses, alarm switches and transmitters, all separately piped to the vessel.

Orion’s twin chamber design is unique to the magnetic level gauge industry. Countless unique configuration styles are available with Gemini. It can be produced in the same metal material selections as Atlas.

The second chamber facilitates the installation of any of a wide selection of transmitters to provide continuous level monitoring in addition to the indication provided by the primary chamber. Eclipse® guided wave radar, direct insertion Jupiter® magnetostrictive, or Kotron® capacitance type level transmitters can be mounted in the secondary chamber to provide totally redundant indication with continuous level output. The primary chamber, which houses the float, can be fitted with clamp-on switches or transmitters for additional level control.
