Product overview
The VTEKE LLR-06 is a multifunction liquid level control relay for automatic filling and draining. Five operating modes support single-tank control with two or three sensors and simultaneous filling/draining control involving two tanks with six sensors. Adjustable sensitivity and delay provide flexible pump control.
