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 rugged construction of the H 250 variable-area flowmeter makes it particularly suitable for difficult application and environmental conditions.
