UQK-71 series dry spring liquid level controllerDetailed product description：

Scope of Application
The UQK-71 series dry spring liquid level automatic controller consists of a liquid level sensor composed of a display instrument and a dry spring tube. Suitable for measuring and remote indication of various conductive and non-conductive liquid levels, the liquid levels of various openings, sealed containers, and underground water tanks can be displayed, alarmed, and controlled inside the instrument control room. Widely used in industries such as power plants, petroleum, chemical, light industry, textile, steel, metallurgy, construction, electromechanical, and mining.

UQK-71 series dry spring liquid level controller model description:

Structural form (model)	result	function
a	A normally open dry spring (upper position) A normally closed dry spring (lower position)	Pump on at high water level Low water level pump shutdown can be matched with DK-10
b	A normally closed dry spring (upper position) A normally open dry spring (lower position)	Stop the pump at high water level Low water level pump can be matched with DK-10
c	A frequently played reed switch (upper position) A frequently played reed switch (lower position)	Implementing automatic control in conjunction with DK-10 motor control box
d	Three frequently played reed switches A normally closed reed switch	Used for upper and lower liquid level control and high and low limit liquid level alarm, compatible with DK-10
e	A normally closed reed switch Three frequently played reed switches	Used for upper and lower liquid level control and high and low limit liquid level alarm, compatible with DK-10
f	Four frequently played reed switches	Implementing automatic control in conjunction with DK-10 motor control box

Note: Controllers that require control of more than 4 points can be negotiated for resolution

working principle
Install several GAG-5 high-power reed switches in the controller, and when the float ball equipped with magnetic steel moves up and down with the liquid level, the contacts of the reed switches will move accordingly, thus achieving the purpose of controlling the liquid level.
