Matheson’s FM-1050 Series Flowmeters provide the most accurate indication and precise control of fluids available for a wide range of applications. This versatile meter is functionally and dimensionally interchangeable with other current designs while incorporating many innovative features.
All FM-1050 Series glass metering tubes have integral float guides to ensure a guaranteed ?5%u0?1%u0ith optional calibration) of full scale accuracy. Both glass and stainless steel floats are included (except for the E910 tube, which includes a glass float only). The meters are available in a range of 150mm reference indicating scales. Be sure to request calibration data for the gas(es) you will be measuring (if no gas is specified, Air calibration data will be supplied).
Standard with this series is the uniquely designed Tube-Cube?. 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 accesss.
Valve Options
. Utility (six-turn) valve for those who desire control as well as indication
. High accuracy (fifteen-turn) valve, for very precise control and repeatability
. No valve for those who just want indication
