Morssinkhof Plastics chooses reliable, leak-free level measurement.

Together with Morssinkhof Plastics, we developed a reliable solution for measuring the level in a buffer tank. The result: a reduced risk of leaks, improved readability, and a solution that may be rolled out to 38 facilities.

Level gauges

Magnetic level gauges operate on the principle of communicating vessels. Consequently, the liquid level in the measuring chamber is the same as the liquid level in the tank.

Inside the measuring chamber is a float containing an enclosed ring magnet. As the float rises and falls with the liquid, the position of the ring magnet indicates the liquid level by actuating the indicator flaps mounted on the outside of the measuring chamber.
