1250AR6041MRSVV 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 R6041 is listed in official Brooks 1250/1255 tables with glass float, 1/8 inch float diameter, 900 CCM air, and 18.2 CCM water millimeter-scale context; exact end-block, valve, seal, and scale details should still be verified from the physical unit label because no verified official exact-part Brooks build sheet is currently available
Configurations vary. Verify the exact unit before choosing a replacement.

Base model context
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 R6041 with glass float, 1/8 inch float diameter, 900 CCM air, and 18.2 CCM water context for millimeter scales
Observed exact-SKU range context
Exact distributor pages describe 1250AR6041MRSVV as an air flowmeter with 0 to 900 CCM range; stored Sonisys auction titles include both 0-900 and 0-990 CCM air wording, so the physical scale should be checked
Performance
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 R6041 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 1250AR6041MRSVV 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
