3750CA5A11WEAAAAA0 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 listing records context. Official Brooks MT3750C documentation supports the metal-tube variable-area identity, low-flow gas/liquid service context, model-code structure, optional flow-controller, transmitter and alarm configurations, and configuration-dependent ratings. The current official model-code table decodes this configured identifier as 316L stainless construction, size 5 with 316L stainless float, standard Viton O-rings, 1/4 in. NPT female integral connection, horizontal inlet/outlet orientation, mounted 316L stainless 8905 flow controller with Teflon diaphragm, 4 VDI / 5% full-scale direct-reading gas scale, no electrical output, no alarm relay or transmitter power supply, no approvals option, no material inspection option, and no listed accessory options
Configurations vary. Verify the exact unit before choosing a replacement.

Specifications
Identification
Part identifier
3750CA5A11WEAAAAA0
Device type
Low-flow armored metal tube variable area flowmeter with integral flow-controller configuration
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 5 maps to size 5 with a 316L stainless steel float for 316L tube construction
Official capacity context for size 5
The Brooks MT3750C capacity table lists size 5 at 1.1-11 gph / 4.2-42 l/h water equivalent and 5.4-53 scfh / 0.15-1.3 m3n/h 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 E maps in the current Brooks table to 4 VDI / 5% full scale, direct-reading gas 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 float and seals
Model-code position VII code 5 maps to a 316L stainless steel float, and position VIII code A maps to standard design with Viton O-rings
Connections
Decoded process connection
Model-code position IX code 1 maps to a 1/4 in. NPT female integral connection, and position X code 1 maps to horizontal inlet and outlet for threaded connections
Controls
Decoded flow-controller configuration
Model-code position XI code W maps to mounted 316L stainless steel 8905 flow controller with Teflon diaphragm
Decoded electrical output
Model-code position XIII code A maps to none in the current Brooks MT3750C table
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 in the current Brooks MT3750C table
Configuration
Decoded inspection and accessories
Model-code positions XVI and XVII code A map to no material inspection option and no accessory; position XVIII code 0 maps to no accessory group 2 option
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 in. NPT configurations; the exact rating for this configured flow-controller unit should be verified from the unit label or Brooks order record before service
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
Applications
Application domain
Low-flow gas or liquid indication and process-support flow control in high-pressure, high-temperature, hazardous, remote, or tight-space industrial applications where the configured scale and materials match the service
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 listing limits
One exact-code listing records reports limits of 1000 psig / 69 bar at 300 F / 149 C; treat this as observed unit-label or seller context, not an official model-wide rating
