The H 250 flowmeter for liquids and gases is an all-metal flowmeter which operates on the float principle.
Depending on the flowrate, the float will assume a certain vertical position in the tube. The float position is transmitted by a magnetic coupling system to the scale. The flowmeter is designed for installation in a vertical pipe run with flow from bottom to top. The rugged construction of the H 250 variable-area flowmeter makes it particularly suitable for difficult application and environmental conditions. The H 250 flowmeter can be equipped with either the M9 or the M10 indicator.

The Easyflow series are flowmeters suitable for the measurement and control of transparent or translucent liquids and gases. The may be fitted with socket or butt weld ends in different materials or flanges, for inline or panel mounting.
They operate on the variable area principle, where a float effectively suspended in upward flowing media in a tapered plastic flow tube. The vertical axial position of the float within the float tube depends on the Flowrate of the media. The plastic flow tube is graduated in suitable flow units, normally with a 10:1 flow range. The reading is taken corresponding with the largest diametric edge of the float.
The Easyflow is a comprehensive range of flowmeters suitable for different flow rates, diameters and tube length.
Features:
• Wide choice of measuring scales
• Wide choice of end connections
• Eight different diameters
• Five different tube length
• Different plastic tube materials
• Different floater materials

Enhanced Flow Meters Feature Direct Reading Scales
Aalborg® is pleased to announce the release of Direct Reading Scales for Models P, S, and T Flow Meters. These flow tube scales are designed exclusively for a specific gas or liquid at a given temperature and pressure valid only for the associated units of flow.
Easy to read flow rates for a specified set of parameters are clearly indicated in specific engineering units, such as mL/min or scfh.
Meters with these scales are more user-friendly. The inconvenience of having to use correlating tables and graphs is eliminated.
NIST traceably calibrated for liquids and gases (argon, carbon dioxide, helium, hydrogen, hydrogen chloride, methane, nitrous oxide, oxygen, and propane), these units are ideal for OEM applications and processing industries. Quick shipping is available.
