Providing liquid level measurement from 1 to 20 ft through magnetic float technology, Series 810 enables plant engineers to continue to monitor material levels despite planned or unplanned power cuts. Sealed measurement chambers are constructed from stainless steel, PVC, PPH, PVDF, or PTFE, which enable measurement of liquids that are corrosive, toxic, or otherwise hazardous. Designs are available to handle fluid temperatures from -256 to 750°F and pressures to 3,480 psi.
