KOBOLD bypass level gauges are used in applications requiring continuous measurement, indication and control of liquid levels. Any medium with viscosity less than 200 cPs is a candidate. KOBOLD’s bypass design relies on the hydrostatic pressure principle to display tank level in a side mounted measuring chamber. A float, containing a ring magnet, rises and falls with the liquid level in the bypass tube. This approach allows an all metal construction which eliminates the breakage and leakage problems frequently experienced with glass tube designs. transmission, visual indication, or switching may be achieved by mounting magnetically sensitive devices on the exterior of the bypass tube. These devices track, or are activated by, the magnet inside the float.
