        Conductivity is a measure of the ability of a given substance to

conduct electric current,  equal to the reciprocal of the resistance of a

substance.  This medium is the most widespread and popular way of

measuring the level of liquid in a tank.  Our liquid level controls can sense

a multitude of different liquids.  (e.g. R.O. water,  beer,  acids,  wine,

milk,  cheeses,  cream,  pharmaceutical products,  salt water, etc.).
