Ameritrol - Model QL Series - Level Switches Brochure

The QL series level switch offers the same reliability as our LX series and also offers a faster response time. The QL series level switch offers versatility not seen in other level control devices. One unit can be field calibrated to detect the interface of air/foam, foam/liquid, oil/emulsion, emulsion/water, oil/water, and a solid in a liquid. The instrument can detect agitation in a tank, vessel, or pond. It can also be used as a universal high level switch that will quickly alarm if any type of liquid comes in contact with the probe. In applications where response time is critical the QL series level switch responds three times faster then our standard LX level switch.
