Design makes each meter suitable for a broad range of laboratory applications
  • Direct-reading flowmeters feature a calibrated scale for a specific medium—no need to convert readings to get flow rate│Dual-unit scales for air or water offer flexibility
  • Features a 1/4″ NPT(M) port and accepts 3⁄8″ ID tubing
  • Maximum pressure range of 100 psi


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.

Glass taper joints are available upon request—call our Application Specialists to order.
