1110-01F1B1U
Brooks Instrument Full-View Glass-Tube Variable-Area Flowmeter
About this part
Brooks Instrument 1110-01F1B1U is a configured identifier within the legacy Full-View 1100 Series. The model 1110 designation identifies an industrial glass-tube variable-area flowmeter with female NPT process connections and horizontally oriented inlet and outlet ports. The meter operates vertically with flow entering at the bottom and exiting at the top. Available manufacturer literature does not decode the complete -01F1B1U suffix; flow range, calibration fluid, tube and float selection, construction materials, seals, connection size and pressure limit must therefore be verified from the unit label and scale
Configurations vary. Verify the exact unit before choosing a replacement.
Key Facts
Specifications
| Manufacturer | Brooks Instrument |
| Product series | Full-View 1100 Series; classified by Brooks Instrument as a legacy product |
| Model and configuration | Model 1110, configured identifier 1110-01F1B1U |
| Operating principle | Direct-indicating variable-area flow measurement using a float in a tapered glass metering tube |
| Metering tube | Borosilicate glass; Full-View 1110/1140 series construction |
| Model 1110 connection type | Female NPT |
| Inlet and outlet orientation | Horizontal process ports; connections can be rotated through 360° in 90° increments |
| Required meter orientation | Within 6° of true vertical, with the inlet at the bottom and outlet at the top |
| Flow accuracy | Standard ±2% of full scale; optional ±1% of full scale for the documented 127, 150 and 250 mm tube configurations. Exact 1110-01F1B1U accuracy option is not identified |
| Repeatability | 0.5% of full scale |
| Ambient temperature | 33 to 125°F (1 to 52°C) |
| Operating-fluid temperature | 33°F (1°C) minimum; up to 250°F (121°C) with metallic end fittings. Nonmetallic fittings have reduced limits |
| Maximum operating pressure | Depends on meter size, fitting material, temperature and approval status; the exact 1110-01F1B1U pressure rating is not established by the available identifier evidence |
| Scale construction and graduation | Detachable aluminum scale plate; configurations were offered with direct-reading units, millimeter graduations or percentage-of-maximum-flow graduations |
| Exact flow calibration | Not established; verify the scale, calibration fluid, reference pressure and temperature on the individual instrument |
| Exact wetted materials and seals | Not established; the series was offered with multiple float, fitting, packing and O-ring materials |
Full-View model distinction
The 1110 prefix identifies the NPT-connected Full-View arrangement with horizontal inlet and outlet ports. Other rows describe sibling arrangements and are not aliases for this part.
| Model | Process connection | Inlet and outlet orientation |
|---|---|---|
| 1110 | Female NPT | Horizontal |
| 1114 | Female NPT | Vertical |
| 1140 | ANSI flange | Horizontal |
| 1144 | ANSI flange | Vertical |
Configuration boundaries
The complete legacy suffix is required to define the calibrated instrument, but a manufacturer-issued decoding key for -01F1B1U was not located.
Installation and glass-tube safety
The manufacturer’s operating manual gives configuration-independent installation and handling requirements for Full-View meters.
- Mount the meter within 6° of true vertical, with the inlet at the bottom and outlet at the top.
- Introduce flow gradually and avoid pressure or flow surges.
- Do not exceed the pressure and temperature limits marked for the configured meter.
- For meter sizes 7–13, retain the protective sleeve over the glass tube and keep the meter windows securely fastened.
- Depressurize the instrument before service or repair.
- Brooks strongly recommends bypass piping so the meter can be isolated for cleaning and service.
Replacement guidance
Brooks Instrument classifies the Full-View 1100 Series as a legacy product. The current GT1600 Series can be configured to retrofit Full-View models 1110, 1114, 1140 and 1144. This is a family-level replacement relationship, not an automatic exact substitute: the replacement configuration must match the installed dimensions, connection arrangement, flow capacity, calibration conditions, materials and pressure requirements.
