3750CA5A51VEKAEAAA is a configured Brooks Instrument MT3750C Series Ar-Mite metal tube variable-area low-flow armored flowmeter. Official Brooks MT3750C documentation identifies the family as low-flow metal tube variable-area flowmeters for liquid or gas service in high-pressure, high-temperature, or hazardous settings, with configurable materials, meter size, seals, connections, valve arrangement, scale, electrical output, approvals, inspections, and accessories. Stored Sonisys auction records identify this exact configured code with Ar-Mite low-flow armored flowmeter wording, but no stored title confirms a calibrated fluid or full-scale range
Configurations vary. Verify the exact unit before choosing a replacement.
