Madison’s CK Series kits combine a continuous liquid level sensor paired with a pre-programmed panel meter display. Each kit offers a turn-key solution for critical tank measurement and process control. In addition to a sensor and panel meter, each kit contains two relays set at 10% and 90%.

The new U5098 ultrasonic sensors provide non-contact continuous level measurement of challenging medias such as sticky, semi-solid, corrosive, and viscous fluids, slurries and even some solids.
