Matheson’s HCE Series Tube-Cube® is the replacement flow tube for FM-1050 Series Flowmeters. The “cube,” a unitized tube holder, aligns the tube quickly and easily for simple tube installation or replacement. The Tube-Cube® provides protection during handling, reducing chipped tube ends, broken tubes and misalignment. The 1.5 X scale magnification lens allows for a more accurate reading. End seals in the FM-1050 are direct acting and nonrotating for fast alignment and convenient service access. SEQHCE0379VA has a direct reading scale of 100-900 sccm-Hydrogen.
All FM-1050 Series glass metering tubes have integral float guides to ensure a guaranteed ±5% of full scale accuracy.
