11XLV8 is an auction-observed Brooks Instrument identifier for a variable-area flowmeter described as air service with a 0 to 400 CCM range. Live research did not find an official Brooks page or exact-part PDF for 11XLV8 itself. distributor evidence for the near-match catalog item 1XLV8 maps the same 0 to 400 CCM air-flowmeter description to Brooks manufacturer model 1250AR6031MRSVV, which is already tracked separately by Sonisys; verify the physical label before treating 11XLV8 as interchangeable with 1XLV8 or 1250AR6031MRSVV
Configurations vary. Verify the exact unit before choosing a replacement.

Identification
Part identifier
11XLV8
Observed manufacturer
Brooks Instrument
Observed device type
Glass tube variable-area flowmeter / rotameter
Research boundary
No official Brooks source currently identifies 11XLV8 as a manufacturer model number; related 1XLV8 and 1250AR6031MRSVV evidence is retained as cross-reference context, not as an exact alias for this record
Relevant Brooks family context
Brooks documentation covers Sho-Rate Models 1250 and 1255 as low-flow glass tube variable-area flowmeters for liquids and gases
Function
Measuring principle
Brooks Sho-Rate family documentation describes variable-area flow measurement using a glass metering tube and float
Performance
1250 family accuracy
Brooks 1250/1255 family documentation lists Model 1250 accuracy as +/-5% full scale at reference conditions
1255 family accuracy
Brooks 1250/1255 family documentation lists Model 1255 accuracy as +/-3% full scale at reference conditions
Family repeatability
Brooks 1250/1255 family documentation lists repeatability as 0.25% full scale
Pressure and temperature
Family pressure and temperature rating
Brooks 1250/1255 family documentation lists 200 psig from 33 F to 250 F / 1 C to 121 C
Construction
Family construction context
Brooks 1250/1255 family documentation lists borosilicate glass, aluminum, 316 stainless steel, clear polycarbonate, and Teflon materials, with aluminum or stainless steel end-block options
Connections
Family connection options
Brooks 1250/1255 family documentation lists 1/8 in NPT with locknuts for aluminum or stainless steel connections and 1/4 in NPT with locknuts for stainless steel connections
Observed configuration
Observed flow context
Stored Sonisys auction titles describe 11XLV8 as a Brooks Instrument variable-area air flowmeter with a 400 CCM full-scale range; this remains observed listing context, not an official 11XLV8 specification
Near-match catalog cross-reference
Distributor data maps catalog item 1XLV8 to Brooks manufacturer model 1250AR6031MRSVV with 0 to 400 cc/min air range; confirm the physical label before merging this 11XLV8 record with that separate manufacturer-model record
Applications
Application domain
Low-flow gas or liquid indication and panel-mounted rotameter service, depending on verified model and configuration
Configuration
Configured-unit rule
Tube, float, scale, valve, end-block material, seal material, connection, calibrated fluid, and flow range must be verified from the unit label and scale markings
