1250AR6031MRSVV is a configured Brooks Instrument Sho-Rate 1250A low-flow glass tube variable-area flowmeter. Official Brooks 1250/1255 documentation identifies the family as precision low-flow glass tube meters for liquids and gases, with configurable tube, float, scale, connection, end-block, valve, and seal options. The configured tube code R6031 is listed in official Brooks 1250/1255 tables with a glass 1/8 inch float and 400 CCM air millimeter-scale context; exact material and valve details should still be verified from the physical unit label because distributor pages for this exact SKU are not official Brooks build sheets
Configurations vary. Verify the exact unit before choosing a replacement.

Current Brooks 1250/1255 model-code documentation identifies 1250A as the 65 mm tube flowmeter base model
Flow
Measuring principle
Variable-area rotameter with glass metering tube and float
Configured tube code context
Brooks 1250/1255 tables list R6031 with glass float, 1/8 inch float diameter, and 400 CCM air context for millimeter scales
Observed exact-SKU range context
Exact distributor pages and stored Sonisys auction records describe 1250AR6031MRSVV as an air flowmeter with 0 to 400 CCM range; treat this as exact-SKU context and verify against the physical scale

1250 accuracy context
Brooks 1250/1255 documentation lists Model 1250 accuracy as +/-5% full scale at reference conditions for listed gases
Repeatability
Brooks 1250/1255 documentation lists repeatability as 0.25% full scale
Pressure / Temperature
Series pressure and temperature rating
Brooks 1250/1255 documentation lists 200 psig from 33 deg F to 250 deg F / 13.8 bar from 1 deg C to 121 deg C
Construction
Metering tube material
Borosilicate glass
Float material context
The R6031 tube entry uses float material code G, which Brooks identifies as glass
Brooks family documentation includes 1/8 inch NPT connection options; exact distributor pages for 1250AR6031MRSVV also list 1/8 inch FNPT connection context
Controls
Valve context
Brooks 1250/1255 documentation includes no-valve, inlet-valve, and limited outlet-valve configurations depending on model and service; exact valve arrangement should be confirmed on the physical unit
Installation
Mounting orientation
Brooks installation documentation describes variable-area meter reading in vertical orientation
Configuration
Configured-unit rule
Tube, float, scale, connection, end-block material, valve arrangement, seal material, calibrated fluid, and flow curve vary by configured code and unit label
Applications
Application domain
Low-flow gas and liquid indication, panel-mounted flow indication, purge service, laboratory flow measurement, industrial flow measurement, and OEM flowmeter applications
