Our 81 series NoFlote Conductivity based level measurement system is well established and robust. A Noflote System comprises one or more 81NE Sensing Electrodes, of the types described later, and either an 81NC Noflote Controller or a BD/BM906/926 DIN Rail Mounting Controller. The controller contains switching circuitry and control relays. The 81NC controller is housed in either a chassis-only form, for cabinet mounting, or in a die-cast aluminium, IP56, weatherproof case. The BM and BD controllers are housed in DIN rail mounting polycarbonate enclosures
A Noflote System detects the electrical resistance between a Noflote electrode and an earth electrode. The earth reference connected to the controller may be the walls of a metal vessel, pipework within the vessel, the earth rod of a multiple sensor or another Noflote electrode.
