The intrinsically safe flow indicator type DA and type DAK can be mounted in any position and monitors the flow of water as well as emulsion in closed and filled systems. The volume flow will be shown as an analogous display.
The flow indicator type DA is for monitoring use only, whereas the flow indicator type DAK has a contact boundary switch integrated for monitoring. Inside the massive brass housing, a contact breaker is fitted to the volume dial. The lower and upper boundaries can be externally adjusted over the whole range of the dial using the key, which is delivered with the unit. In addition, the flow indicator can be equipped with different electrical wiring and connections, e.g. with resistors for cable monitoring.
