The H 250 flowmeter for measurement of the volumetric or mass flow rate of liquids, gases and steam is an all-metal flowmeter that operates on the float measuring principle. The flow-dependent vertical position of the float in the measuring tube is transmitted by a magnetic coupling system to the scale in the indicator part. The flowmeter is installed in a vertical pipe run, with flow from bottom to top. Owing to its rugged design, the H 250 variable-area flowmeter is particularly suitable for difficult applications and environmental conditions.D
In the M9 indicator, the vertical position of the float is transmitted to the pointer/ magnet system, and the flow value indicated directly on the scale.D
