Ordering & Selection Considerations VEGA FLEX 81

Ordering & Selection Considerations

When specifying a VEGA FLEX 81, key selection parameters include:

• Probe type (cable, rod, or coaxial) based on range and medium properties

• Wetted material (316L, Alloy C-22, etc.) for chemical compatibility

• Process connection (flange, thread, etc.) to match the vessel

• Sealing system (standard vs. ammonia-specific dual seal)

• Housing material & rating (plastic, aluminum, stainless steel) for environmental conditions

• Output protocol & approvals (hazardous area, SIL, etc.)

• Display/configuration (optional integrated LCD for local setup)

Summary

The VEGA FLEX 81 is a high-performance guided wave radar level transmitter that delivers reliable, accurate measurements across a wide range of liquids and challenging process conditions. Its flexible probe options, robust construction, and low-maintenance design make it a versatile choice for demanding level and interface applications in the process industry.
