I、Use:：
LRUQK type float level controller is suitable for liquid level control in the industrial production process of open or pressure container liquid. Such as liquid level arrived at high and low limit, the relay contact can be used as signal alarm device or electric pump switch in a circuit.

II、Technical parameter：
1.25～550mm  level adjustment  Horizontal
2.Working pressure: 1MPa（Copper), 0.3MPa(Aluminum)
3.Working temperature: 150℃
4.Contact capacity of the power: AC220V,220VA    DC100V,150W
5.Action range adjustment method: To achieve by regulating the up-down positioning screw on the segment gear(change swing angle of the floating ball) or remove the split pin in different length of the connecting rod(change swing radius of the floating ball).
6.The controller is non waterproof structure, not suitable for used in the outdoor open-air places.
7.When installation the controller of the metal shell should connected to the ground  reliable (generally connected to the flange) to ensure the safety of electricity use.
8.The controlled medium should not contain magnetic impurities, and the liquid surface wave frequency can’t be too big.
9.The instrument in using should be check regularly.
