3750CA2A51TEKAEAAA 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 transmitter/alarms, and configuration-dependent ratings. The current official model-code table decodes the supported positions as 316L stainless construction, size 2 with 316L stainless float, standard Viton O-rings, 1/2 in. NPT female connection with adapter, horizontal inlet/outlet, direct-reading gas scale, MAT transmitter with 1/2 in. NPT electrical connection, Division 2/Zone 2 CSA non-incendive approval context, no listed power-supply, material-inspection, or accessory options; however, the current table does not define code T at the valve-configuration position or code A at accessory group 2, so those positions should be verified from the physical nameplate, order record, or a legacy Brooks code table
Configurations vary. Verify the exact unit before choosing a replacement.
Application classIndustrial automation and process equipment
CategoryFlow Control
Specifications
Identification
Part identifier
3750CA2A51TEKAEAAA
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 2 maps to size 2 with a 316L stainless steel float for 316L tube construction
Official capacity context for size 2
The Brooks MT3750C capacity table lists size 2 at 0.096-0.96 gph / 0.36-3.6 l/h water equivalent and 13.0-120 ln/h / 0.5-4.9 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 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 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 5 maps to 1/2 in. NPT female connection with adapter, and position X code 1 maps to horizontal inlet and outlet for threaded connections
Controls
Decoded electrical output
Model-code position XIII code K maps to a MAT transmitter with 1/2 in. NPT female electrical connection 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 E maps to Division 2/Zone 2 non-incendive CSA - USA and Canada for transmitter 1/2 in. NPT and alarm configurations in the current Brooks MT3750C table
Configuration
Unsupported current-table code positions
The current Brooks MT3750C model-code table does not define T at valve-configuration position XI or A at accessory-group-2 position XVIII; verify those positions against the physical unit, Brooks order record, or applicable legacy code table
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 pressure rating for this configured unit must be verified because the valve code is not decoded from the current table
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 measurement 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 low-flow armored flowmeter and MT3750 / 3750C-MAT context; this is identity and observed-configuration evidence only
