UHC magnetic float liquid level indicator UQC magnetic ball float liquid level indicator Summary UHC series magnetic float liquid level indicators and UQC series magnetic ball float liquid level indicators are new designed generation liquid level indicator according to magnetic coupling principle. They present the level indication directly and clearly because of the advanced technology and the proper structure and are suitable for liquid level measurement in petroleum, chemical, power, light industry and pharmaceutical industrial field, etc. UHC series magnetic float liquid level indicators are mounted on side of vessels, while UQC series magnetic ball float liquid level indicators are mounted on the top of vessels especially for the measurement for the underground storage tanks.

UHC series magnetic float liquid level indicators are mounted and connected on the side of vessels. When the float moves up and down with the liquid level (interface level) changing, the magnet steel inside the float drives the magnetic flakes inside of the indicator to roll over according to magnetic coupling principle. All the magnetic flakes are coated with red one side and blue other side. The continuous red or blue zone (red represents the liquid, while blue represents air or gas) can clearly indicate actual liquid level or interface level inside of vessels.

With the liquid or interface level changing, the ball float will move up and down and drive the magnetic connecting rod goes up and down. The magnet steel inside of the connecting rod drives the magnetic flakes inside of the indicator to roll over according to magnetic coupling principle. All the magnetic flakes are coated with red one side and blue other side. The continuous red or blue zone (red represents the liquid, while blue represents air or gas) can clearly indicate actual liquid level or interface level inside of vessels. With remote transducers and upper, lower alarms equipped, the UHC, UQC series indicators can realize to remotely transmit the liquid level signal and perform automatic control.
