Brooks Instrument 1305FL1ACJ2AA Glass Tube Flow Meter

Brooks Instrument 1305FL1ACJ2AA Glass Tube Flow Meter is a compact inline glass-tube variable-area flowmeter (rotameter) that provides direct visual indication of flow rate for gases and liquids in process lines. Rated to 150 PSIG and 200 F, it supports moderate-temperature, moderate-pressure service, with a float moving inside a borosilicate glass tube to create a readable flow position on a calibrated scale. This model is part of Brooks Instrument’s GT130x family of glass-tube VA flow meters, designed for economical, straightforward flow measurement in laboratory and industrial environments. Its glass-tube construction allows easy observation of the float and simple inspection of the flow path, making it suitable for clean liquids and gases in applications such as chemical dosing and general process monitoring where visual flow indication is sufficient. The 1305 series embodies Brooks’ long-standing approach to reliable, low-maintenance flow indication in a simple, inline form factor for use in a variety of laboratory and process settings.
