Thermo Scientific™ Gilmont laboratory direct-reading flowmeters have excellent chemical compatibility with glass and PTFE construction. Flowmeter measurements can be read directly off the flowmeter.

Choose from unshielded, shielded, or shielded with valve flow meters suitable for a wide range of applications.

Unshielded Flowmeters work well in low-pressure applications. Connect the flowtube end directly to tubing having the proper inner diameter. Maximum pressure rating for unshielded flowmeters is 15 psi.

Shielded Flowmeters are better suited to higher-pressure applications or for installations requiring a panel-mounted flowmeter. End bushings are molded with dual connection capability—tubing or threaded.

Shielded Flowmeters with Valves offer flow monitoring along with precise control through an integrated 20-turn micrometer valve. The valve can be adjusted from 0.1 to 100% of maximum flow (semilogarithmic) and provides recise regulation from 0.3 to 60% of maximum flow.
