Brooks Instrument 1110DG41CSAAR is a legacy Full-View Model 1110 variable-area flowmeter configured with 1/4-inch female NPT horizontal inlet and outlet connections, a size-6 R-6-25-A borosilicate metering tube, a spherical 316 stainless-steel float, steel fittings with PTFE packing and O-ring, and a special ±1% full-scale water calibration. The ordering code also specifies NIST traceability. Brooks publishes 485 cc/min water as the reference maximum capacity for the code-matched tube and float; the serialized meter scale remains authoritative for its calibrated range
Configurations vary. Verify the exact unit before choosing a replacement.

Installation and operating notes
Install the flowmeter within 6 degrees of true vertical, with flow entering at the bottom and leaving at the top.
Introduce flow slowly and avoid pressure or flow surges.
Brooks recommends bypass piping so the meter can be isolated for servicing and cleaning.
Do not exceed the applicable pressure or temperature limits or service the meter while it is pressurized.
Legacy status and replacement
Brooks classifies the Full-View 1100 Series as a legacy product.
Current replacement familyBrooks GT1600 Series
Compatibility scopeThe GT1600 can be configured to retrofit Full-View models 1110, 1114, 1140, and 1144.
Selection requirementA replacement must be configured for the original connection arrangement, capacity, wetted materials, and calibration; family-level retrofit capability does not establish a direct one-for-one replacement for 1110DG41CSAAR.
