SP-GA Series Liquid Flow Switch

The SP-GA Flow Switch is designed to give an initial alarm at a very low flow and still capable of allowing a high full liquid flow passing through when pumps or valves are activated by the micro switch. This is since the SP-GA Flow Switch is designed with a variable flow passage area which increases as the liquid flow rate increases. The SP-GA is also equipped with an internal rubber diaphragm to make the switch even more sensitive at low liquid flows. As the disc inside is spring loaded, it is possible to install the Eletta SP-GA Flow Switch in any position, vertical, horizontal or even up side down. This gives an advantage over other types of flow switches such as Rotameters, Target or Paddle, which generally requires vertical mounting. The function is based on fluid flow activation only and therefore it is not affected by changes in static pressure.
