Flow Measurement
3609EC2C2K1A
Brooks Instrument High-Pressure Metal-Tube Thru-Flow Indicator
About this part
Brooks Instrument 3609EC2C2K1A is a configured member of the legacy 3604/3609 high-pressure thru-flow-indicator line. It is a mechanical metal-tube variable-area flowmeter intended for local, inline flow indication. The calibrated fluid, flow range, scale units, wetted materials, connection standard, and allowable pressure-temperature envelope are configured-unit data and must be taken from the instrument scale and nameplate. Exact-identifier marketplace evidence reports a 1-1/2-inch size and a 240 psi marking; these details are retained as observed configuration rather than universal manufacturer specifications
Configurations vary. Verify the exact unit before choosing a replacement.

Nameplate Data Required for Engineering Use
The complete configured model cannot be safely selected, installed, or replaced from the abbreviated marketplace description alone.
- Confirm the calibrated process fluid and any stated specific gravity, density, or viscosity.
- Read the full scale range, engineering units, and scale reference conditions directly from the instrument.
- Confirm the process-connection size and type, including flange class and facing where applicable.
- Verify all wetted materials and seal materials for process compatibility.
- Use the nameplate or manufacturer-certified record for maximum pressure and temperature limits; do not interpret the observed 240 psi marking without its context.
- Confirm required installation orientation and flow direction before returning the instrument to service.
