3750CA4A11CEAAAAA0 is a configured Brooks Instrument MT3750 / Ar-Mite low-flow armored metal-tube variable-area flowmeter identifier. Stored auction records and exact listing records identify it as an MT 3750 / MT3750 armored flowmeter, with one observed listing title giving a 2.5-24 SCFH range. The old automated extraction treated 'Ar' as a gas, but that appears to come from the Ar-Mite product-family name rather than an argon calibration claim. Exact process connection, material, float, elastomer, pressure rating, temperature rating, valve, and alarm/transmitter options should be verified from the physical unit label
Unit-specific configuration
