Brooks Instrument Sho-Rate 1250A Glass Tube Air Flowmeter
About this part
1250AD6073AFSVV 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 D6073 air table row is listed with a stainless-steel 1/4 inch float, 0.2 to 11.4 LPM air context, and 2.5 to 25 SCFH air context; exact installed hardware and scale markings 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.

Specifications
Identification
| Device type | Direct-reading glass tube variable-area flowmeter |
| Series family | Brooks Sho-Rate 1250/1255 Series |
| Configured model code | 1250AD6073AFSVV |
| Base model context | Brooks model-code documentation identifies 1250A as the 65 mm tube flowmeter base model |
Flow
| Measuring principle | Variable-area rotameter with tapered borosilicate glass metering tube and metering float |
| D6073 air LPM context | Brooks 1250/1255 documentation lists D6073 in the Model 1250 Air direct-reading table with stainless-steel 1/4 inch float and 0.2 to 11.4 LPM air range |
| D6073 air SCFH context | The same Brooks D6073 Model 1250 Air table entry lists 2.5 to 25 SCFH air context |
| Observed exact-SKU range context | Distributor catalog pages and stored Sonisys auction evidence for this exact manufacturer part number describe an air flowmeter with 2 to 25 SCFH or 2.5 to 25 SCFH wording; this is retained as observed catalog/listing context, not as a replacement for the official Brooks D6073 table row |
Configuration
| Code interpretation boundary | The configured code is consistent with 1250A base model, D6073 tube/table context, air service, SCFH unit-of-measure context, 1/8 inch FNPT stainless end-block context, standard inlet valve context, and Viton O-ring context; verify installed hardware from the physical label |
| Configured-unit rule | Tube number, float material, direct-reading scale, end-block material, connection, valve, O-ring material, and process-fluid assumptions must be verified from the specific unit and documentation |
| Reference conditions | Brooks 1250/1255 data sheet states reference conditions of 70 deg F (21.1 deg C) and 14.7 psia (1 bar absolute) for listed gas accuracy context |
Performance
| 1250 family accuracy | Brooks 1250/1255 data sheet lists 1250 accuracy as +/-5% full scale at reference conditions for listed gases |
| Repeatability | Brooks 1250/1255 data sheet lists repeatability as 0.25% full scale |
Pressure and temperature
| Series-level pressure/temperature | Brooks 1250/1255 data sheet lists 200 psig from 33 deg F to 250 deg F / 13.8 bar from 1 deg C to 121 deg C; verify the configured unit and application before using this limit |
Materials
| Series-level materials | Brooks 1250/1255 data sheet lists borosilicate glass, aluminum, 316 stainless steel, clear polycarbonate, and Teflon in materials of construction |
| D6073 float material | Brooks 1250/1255 documentation lists D6073 with stainless-steel float material and 1/4 inch float diameter |
| Seal options | Brooks 1250/1255 data sheet lists Buna and Viton packing/O-ring options; the configured code ending in V identifies Viton O-ring context for the standard valve configuration |
Connections
| Connection options | Brooks 1250/1255 data sheet lists 1/8 inch NPT with locknuts for aluminum or stainless steel and 1/4 inch NPT with locknuts for stainless steel only |
| Configured connection context | The model-code S position is listed by Brooks as 1/8 inch FNPT stainless steel end blocks; distributor pages for the exact manufacturer part number also identify 1/8 inch FNPT connection context |
Valve
| Valve options | Brooks 1250/1255 data sheet lists no-valve, standard inlet-valve, and limited outlet-valve configurations depending on service |
| Configured valve context | The model-code V position is listed by Brooks as standard inlet valve context |
Installation
| Mounting orientation | Brooks installation documentation describes variable-area meter use in vertical orientation |
Maintenance
| Tube assembly service | Brooks documentation describes quick removal or installation of tube and float while the meter remains in process piping, and the data sheet describes EZ-CHANGE tube assembly interchangeability |
Applications
| Application domain | Low-flow gas and liquid indication in laboratory, industrial, and OEM applications; this configured part is identified by source evidence as an air/SCFH configuration |
