Kelco is a specialist manufacturer of corrosion resistant flow and level switches. These are used in a wide range of applications; from the water industry through to process applications where aggressive liquids are often used. Our paddle and in-line flow switches can be supplied with a variety of switch modules; and some of the paddle switches feature built-in time delay. Our level switches offer a variety of configurations, allowing some unique methods of level control.

■ V25 VISUAL FLOW or LEVEL INDICATORS     Insertion style inferential flow or level indicators that     work magnetically to give a bright green or bright red     indication. Unlike conventional inline flow indicators,     the V25F does not suffer from dirty windows obscured     by lime scale, rust or algae buildup, and can also be     used in effluent and highly turbid liquids. The V25F can     be fitted into pipe sizes 25mm or larger. The V25L     visual level indicator is ideal for water tanks, chemical     holding tanks and dieseline fuel tanks. •   Read more

■ PGF-60PP DIAPHRAGM SEAL PRESSURE    GAUGES     The PGF-60PP is a silicone oil filled diaphragm seal     gauge that can be used reliably in applications where     conventional gauges would fail.  In situations where     corrosive or aggressive liquid is being processed, the     outstanding chemical resistance of Viton and     polypropylene combined with the proven advantages     of a silicone oil buffer make for a very long service life     even in the most difficult situations.     The PGF-60PP is ideal for dirty water and effluent     applications.   •  Read more
