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 M7 indicator.
In the M9 indicator, the rotational movement of the follower magnet system is transmitted to the indicator without being linearized and the flowrate value is indicated directly on the scale.
In the M7 indicator, the rotational movement of the follower magnet system is mechanically linerarized via a cam plate and the flowrate is indicated on the scale.
