3750CA1A11ACAAAAA0 is a configured Brooks Instrument MT3750C / Ar-Mite low-flow armored metal tube variable-area flowmeter identifier observed in Sonisys stored auction records and exact surplus-listing context. Official Brooks MT3750C documentation identifies the 3750C base model as a 55 mm armored purge flowmeter and decodes this configured code as 316L stainless steel construction, size 1 with 316L stainless steel float, standard Viton O-rings, 1/4 inch NPT female integral horizontal connections, no valve, 4 VDI / 5% full-scale direct-reading liquid scale context, no electrical output, no relay or transmitter power supply, no selected approval, no material inspection, and no accessory options. Exact scale marking, service fluid, pressure limit, temperature limit, and calibration should still be verified from the physical unit label before operational use
Configurations vary. Verify the exact unit before choosing a replacement.

Specifications
Identification
Part identifier
3750CA1A11ACAAAAA0
Device type
Low-flow armored metal tube variable-area flowmeter
Series family
Brooks Ar-Mite MT3750C Series
Configured model prefix
Brooks model-code documentation identifies 3750C as the 55 mm armored purge flowmeter base model
Flow
Measuring principle
Variable-area metal tube flow measurement with magnetically coupled local indication
Series service context
Brooks MT3750C literature describes the family for low-flow gas and liquid applications, with flow range depending on meter size, fluid, scale, float, and calibration
Decoded meter size context
Model-code position VII code 1 maps to size 1 with a 316L stainless steel float for 316L tube construction
Official capacity context for size 1
The Brooks MT3750C capacity table lists size 1 at 0.034-0.34 gph / 0.13-1.3 l/h water equivalent and 5.6-56 ln/h / 0.21-2.1 scfh air equivalent at stated reference conditions; verify the installed scale and calibration before operational use
Performance
Series rangeability
Brooks MT3750C documentation lists 10:1 rangeability for most sizes
Decoded accuracy and scale context
Model-code position XII code C maps in the current Brooks table to 4 VDI / 5% full-scale direct-reading liquid scale
Series repeatability
Brooks MT3750C documentation lists repeatability as 1% full scale
Materials
Decoded construction
Model-code position VI code A maps to 316L stainless steel construction in the current Brooks MT3750C table
Decoded seals
Model-code position VIII code A maps to standard design with Viton O-rings in the current Brooks MT3750C table
Connections
Decoded process connection
Model-code position IX code 1 maps to 1/4 inch NPT female integral connection, and position X code 1 maps to horizontal inlet and outlet for threaded connections
Controls
Decoded valve configuration
Model-code position XI code A maps to no valve, standard fitting with plug
Decoded electrical output
Model-code position XIII code A maps to no electrical output
Alarm relay or transmitter power supply
Model-code position XIV code A maps to none in the current Brooks MT3750C table
Approvals
Decoded approval context
Model-code position XV code A maps to no certification or approval option selected in the current Brooks MT3750C table
Configuration
Inspection and accessories
Material inspection A, accessory A, and accessory group 2 code 0 indicate no additional inspection, accessory, or second accessory-group option selected in the model code
Ratings
Series pressure context
Brooks MT3750C documentation lists 1500 psig / 100 bar standard maximum fluid pressure and a 4000 psig / 276 bar high-pressure option for no-valve 1/4 inch NPT configurations; verify the exact unit label and application limits before use
Series temperature context
Brooks MT3750C documentation lists maximum fluid temperature up to 204 C / 400 F depending on ambient temperature, electronics, and elastomer material; Viton seal context does not by itself verify the configured unit's complete temperature rating
Observed Listing Context
Exact-code listing identity
Stored Sonisys auction records and exact listing records context identify this configured code as a Brooks Instrument Ar-Mite / MT 3750 low-flow armored flowmeter; this is identity and observed-configuration evidence only
Observed scale and rating wording
Exact listing evidence reports 0.13-1.3 l/h water at SG 1.0 and 1500 psig / 103 bar at 400 F / 204 C wording for the observed unit; verify against the physical nameplate and scale before use
Applications
Application domain
Low-flow liquid or gas indication and process-support flow measurement in high-pressure, high-temperature, hazardous, remote, or tight-space industrial applications where the configured scale and materials match the service
