G120924-1
Brooks MT 3809 Metal-Tube Variable-Area Flow Meter ( )
About this part
The G120924-1 record corresponds to an observed Brooks MT 3809 metal-tube variable-area flow meter. The MT 3809 uses a magnetically coupled float and dial pointer to indicate flow in gas, liquid, or steam service. Flow range, calibration fluid, connection, materials, pressure and temperature limits, accuracy option, and installed electronics are configuration-specific and are not established by G120924-1 alone
Configurations vary. Verify the exact unit before choosing a replacement.
Key Facts
Specifications
| Record identifier | G120924-1 |
| Manufacturer | Brooks Instrument, LLC |
| Observed model association | MT 3809; G120924-1 is not defined as a model or ordering code in published Brooks MT3809 literature |
| Instrument type | All-metal variable-area flow meter |
| Measurement principle | A magnet encapsulated in the float couples to a magnet behind the indicator and drives the dial pointer |
| Documented services | Gas, liquid, and steam flow measurement |
| Accuracy options | Legacy MT 3809 manual specifies ±2% of full scale standard and ±1% of full scale optional; the configured accuracy of G120924-1 is not established |
| Repeatability | 0.25% of full scale for the legacy MT 3809 family |
| Cataloged capacities | Across legacy MT 3809 size and float configurations: water 25–100,000 l/h (0.11–440 gpm) and air 0.49–750 scfm; these are family limits, not the range of this unit |
| Construction choices | Stainless-steel construction is standard; manufacturer literature lists configuration-dependent float, wetted-material, flange, threaded-connection, housing, alarm, and transmitter choices |
| Orientation | Install within 5° of true vertical, with the inlet at the bottom and outlet at the top |
| Exact ratings and calibration | Obtain the calibrated range, units, process fluid, connection, materials, pressure and temperature ratings, and approvals from the unit scale, labels, or manufacturer record |
