Specifications

A flow indicator is used to measure the flow of liquid, powder or gas through pipelines. Because most applications that run through pipelines require visual inspection at some point in the piping system, visual flow indicators are used in line. L.J. Star supplies different varieties of inline sight glasses that are available for all industries.

Our flow indicators meet or exceed pressure and temperature ratings, which vary depending upon the sight glass design. Materials of construction used in the sight glass must also be suitable for specific processes, as well as the metals, gaskets, and glass used in a flow indicator. View options include standard inline and full 360° views.

ANSI flange and NPT type connection visual flow indicators are available in many different materials – carbon steel, stainless steel, hastelloy, monel and those with a Teflon® lining. They are the best design available, made of investment cast bodies with independently bolted retainers to ease any routine maintenance an increase safety.
