Brooks Instrument Full-View Glass-Tube Variable-Area Flowmeter
About this part
Brooks Instrument 1110-01H1G1A is a configured Model 1110 Full-View industrial glass-tube variable-area flowmeter with female NPT process connections. Brooks identifies the Full-View 1100 Series as a legacy product. The exact listing's primary photograph visibly confirms a 60–660 cc/min air scale at 70 °F and 7.35 psig and vertical end connections on that unit. Tube, float, wetted materials, calibration, and pressure limit still require the meter nameplate or calibration record
Configurations vary. Verify the exact unit before choosing a replacement.

Legacy Configuration Code
The suffix “-01H1G1A” belongs to a legacy configuration format. Current Brooks 1110/1140 ordering literature uses a different code layout, so its modern position meanings must not be applied to this identifier. Tube number, float material, packing, O-ring, orientation and calibration should be taken from the original nameplate, scale inscription or calibration record.
Installation and Operating Notes
- Install the flowmeter within 6 degrees of true vertical, with the inlet at the bottom and the outlet at the top.
- Introduce flow slowly and avoid pressure or flow surges.
- Do not operate above the pressure and temperature limits assigned to the configured meter.
- Isolate and depressurize the meter before service or disassembly.
- For affected larger meter sizes, the protective tube sleeve must remain installed and the meter windows must be secured.
Replacement Relationship
Brooks identifies the GT1600 Series as the current configurable retrofit family for Full-View 1100 Series meters. Retrofit suitability is family-level and does not establish a drop-in GT1600 ordering code for 1110-01H1G1A.
