Kofloc Model RK1000 Purge Flowmeter

Description

The Kofloc Model RK1000 Purge Flowmeter is engineered for versatility and longevity. It utilizes a precision-tapered borosilicate glass tube and a calibrated float to provide a linear scale that is easy to read at a glance. Its “Purge” designation highlights its optimization for maintaining a small, steady flow of gas or liquid—critical for protecting sensitive sensors, preventing clogging in sample lines, or maintaining inert atmospheres.

A standout feature of the Kofloc Model RK1000 Purge Flowmeter is its modular design. The glass tube and float assembly can be easily removed for cleaning or replacement without disconnecting the entire meter from the piping, significantly reducing maintenance downtime. Available in both Brass and Stainless Steel, this meter is compatible with a wide range of fluids, including Air, Nitrogen, Argon, and Water. Its robust frame ensures that the delicate glass components are shielded from mechanical stress and impact, making it a dependable choice for both laboratory benches and harsh factory floors.
