B-82DB
Brooks Instrument Mechanical BiRotor Positive Displacement Flow Meter
About this part
B-82DB is a legacy Brooks Instrument mechanical BiRotor positive displacement flow meter identifier associated with the 4-inch B08/B080 BiRotor family. Official Brodie International sources support the current legacy BiRotor family context and the Brooks Instrument lineage of the product line, while an exact-code Brodie/Brooks-style data-sheet mirror cross-references B-82DB to a 4-inch, 150 lb ANSI, 150 psi configuration. Stored Sonisys auction evidence is retained only for exact-code identity, observed register configuration, image evidence, and historical price context
Unit-specific configuration
Historical listing records identify this part as 600 GPM. 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.
Key Facts
Specifications
| Part identifier | B-82DB |
| Observed manufacturer wording | Brooks Instrument |
| Product-line lineage | Brodie International documents that the BiRotor product line previously moved under the Brooks Instrument banner and was later re-branded as Brodie International |
| Device type | Mechanical BiRotor positive displacement liquid flow meter |
| Family context | B08/B080 4-inch BiRotor family |
| Exact-code cross-reference | A Brodie/Brooks-style model-code selector mirror lists B-82DB as a 4-inch, 150 lb ANSI, 150 psi old-model number cross-referenced to selector B080A |
| B08 family flow range context | Official Brodie BiRotor family data lists model code B08 as a 4-inch meter with 60-600 GPM flow range |
| Measurement principle | BiRotor positive displacement meter using two rotors; mechanical versions use a gear train to transfer rotor motion to a mechanical or electronic register |
