The H 250 flow meter for liquids and gases is an all-metal flow meter, which operates via float principles. Depending on the flow rate, the float will assume a certain vertical position inside the tube. The float position transmits by a magnetic coupling system to the scale.
It is designed for installation in a vertical pipe, with flow from bottom to top. The rugged construction of the H 250 variable area flow meter makes it particularly suitable for difficult application and environmental conditions.
In the M7 indicator, the rotational movement of the follower magnet system is mechanically linearized via a cam plate and the flow rate is indicated on the scale.
