1110DK41CMDAA
Brooks Full-View Industrial Glass-Tube Variable-Area Flowmeter
About this part
Brooks 1110DK41CMDAA is a configured Full-View 1110 Series variable-area flowmeter for gas service. The manufacturer ordering code specifies a size 9 meter with horizontal 3/4-inch female NPT inlet and outlet connections, a 250 mm R-9M-25-3 metering tube, a 9-RV-33 float in 316 stainless steel, a special gas scale inscription, 316 stainless-steel end fittings, PTFE packing and O-ring, and no encoded accessories. The gas species and full-scale flow range are not encoded and must be read from the scale or unit documentation
Configurations vary. Verify the exact unit before choosing a replacement.

| D | Materials of construction | 316 stainless-steel fittings with PTFE packing and PTFE O-ring |
| A | Connection type | NPT |
| A | Accessories | None |
Scale and Flow-Range Qualification
Code M establishes a special gas scale inscription but does not identify the gas species, reference conditions, engineering units, or full-scale flow value. Those details must be taken from the installed scale, nameplate, calibration record, or an exact manufacturer build record.
Installation and Safety Notes
- Mount the metering tube within 6 degrees of true vertical, with flow entering at the bottom and leaving at the top.
- Keep the protective sleeve over the glass tube and fasten the meter windows securely; these requirements apply to size 9.
- Introduce flow slowly and avoid pressure or flow surges.
- Do not service the meter while it is pressurized, and do not exceed the documented pressure or temperature limits.
Legacy and Replacement Context
Brooks identifies the GT1600 Series as configurable to retrofit Full-View 1100 Series meters, including model 1110. This is a family-level replacement path, not proof of a drop-in GT1600 replacement for 1110DK41CMDAA. Replacement selection must reproduce the connection geometry, tube and float capacity, gas scale, materials, pressure rating, and process conditions.
