Flowmeter FM-1050 Series

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% (±1% with optional calibration) of full scale accuracy. Both glass and stainless steel floats are included. 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. 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 no rotating for fast alignment and convenient service access.

 

• No valve for those who just want indication
