M/T3750A is a Brooks Instrument variable-area flow-meter identifier observed in surplus and auction records. Official Brooks documentation located during research covers the MT3750C / Ar-Mite low-flow metal-tube variable-area flowmeter family, not a literal M/T3750A exact-part PDF, so family specifications are provided as context only. Exact configured code, flow scale, fluid service, fittings, materials, pressure rating, options, and calibration should be verified from the physical unit label
Unit-specific configuration
Observed configuration
Historical listing records identify this part as 0-5 SCFH. Exact gas, range, fittings, valve configuration, and communication interface must be verified from the physical unit label.
Configurations vary. Verify the exact unit before choosing a replacement.

CategoryFlow Control
Specifications
Identification
Device type
Variable area flow meter; exact construction and scale depend on the configured unit
Manufacturer context
Brooks Instrument
Family documentation context
Brooks documentation covers the MT3750C / Ar-Mite low-flow metal-tube variable-area flowmeter family; it was used only as family context because no verified official exact M/T3750A PDF is currently available
Flow
Measuring principle
Variable-area flow measurement with local indication; official MT3750C family documentation describes magnetically coupled indication
Family liquid capacity range
MT3750C family documentation lists water-equivalent ranges from 0.025-0.25 gph / 0.096-0.96 l/h through 2.8-26 gph / 11-100 l/h depending on meter size
Family gas capacity range
MT3750C family documentation lists air-equivalent ranges from 2.4-15 ln/h through 12-110 scfh / 0.31-3.1 m3n/h depending on meter size
Performance
Family rangeability
MT3750C family documentation lists 10:1 rangeability for most sizes
Family accuracy and repeatability
MT3750C family documentation lists accuracy options of 5%, 3%, VDI/VDE class 4, or class 2.5 depending on configured meter, and repeatability of 1% full scale
Materials
Family wetted materials
MT3750C family documentation lists 316L stainless steel or Monel K-500 metering tubes and end fittings, with 316L stainless steel or titanium Grade II floats
Connections
Family connection options
MT3750C family documentation lists 1/4 inch to 3/4 inch NPT female, 1/4 inch tube compression, and 6 mm tube compression options
Ratings
Family pressure and temperature context
MT3750C family documentation lists 1500 psig / 100 bar standard maximum fluid pressure, 4000 psig / 276 bar high-pressure option for no-valve 1/4 inch NPT units, and maximum fluid temperature up to 204 C / 400 F subject to options
Controls
Family option context
MT3750C family documentation lists optional needle valves, cartridge or NRS valves, integrally mounted flow controllers, reed switches, inductive switches, and 4-20 mA transmitter options depending on configuration
Configuration
Configured-unit rule
Flow scale, fluid service, connection, material package, float, elastomer, pressure rating, temperature rating, valve, transmitter, alarm, and approvals vary by configured model code and physical nameplate
Observed variants
Stored auction configuration contexts
Stored and listing evidence includes M/T3750A units marked with configured codes 3750A2AFF1A1A and 3750A5AFD1A1A, including observed 0-5 SCFH with 1/4 inch NPT and 0-100 GPH with 1/4 inch NPT contexts; these are listing-specific observations, not universal specifications
Applications
Application domain
Industrial gas or liquid flow indication and process-support flow measurement where the configured flowmeter scale and materials match the service
