New-Flow BF300E Metal Tube Variable Area Flow Meter 0-1200 L/H Water 1" 150# RF

New-Flow BF300E Metal Tube Variable Area Flow Meter 0-1200 L/H Water 1" 150# RF

The New-Flow BF300E is a metal tube variable area flow meter — commonly called a rotameter — designed for measuring high flow rates of water, gas, liquid, and steam in industrial inline piping systems. The float rises within a precision-tapered metal tube in proportion to flow, and the rate is read directly from the large analog dial gauge on the front face. The SS316 stainless steel construction makes this meter well suited to corrosive or high-pressure/high-temperature process environments where glass-tube rotameters are not appropriate.

Applications

Metal tube variable area flow meters like the BF300E are standard instruments in industrial process plants, chemical processing, water treatment, HVAC systems, and utilities where robust inline flow measurement is required. Unlike glass-tube rotameters, the all-metal construction allows use in higher-pressure and higher-temperature service lines, as well as in aggressive or opaque media where a glass tube would be unsuitable or unsafe. The flanged 150# RF connection makes direct installation into standard ANSI-class piping straightforward. These meters are commonly found in water distribution systems, boiler feed lines, cooling water circuits, and gas distribution manifolds. The direct-reading analog dial requires no external power, making the BF300E practical in remote or hazardous areas where powered instrumentation is less desirable. New-Flow is an ISO 9001-certified manufacturer of flow instrumentation, and the BF300E series reflects a mid-2000s to present generation of flanged metal tube rotameters widely used across process industries.
