The industrial range of self-powered tank contents gauges have been designed to give a simple but effective and coninuous read-out of tank contents. We are able to offer three sizes of indicator 100mm, 160mm or 250mm, all of which are stainless steel and weatherproof. There are five types of sensors, two external mounting and four internal types, and with all the sensor types available in Mild Steel, Brass and 316 Stainless Steel most applications can be met from the range available. This range of gauges has also been developed to accept a pressure transmitter from which a 4-20mA signal can be received, or a mechanical switching unit that allows micro switches to operate at pre-set levels of tank contents.
