The device works on the well known float principle but without the use of the open conical measuring tube.
The device works on the well known float principle but without the use of the open conical measuring tube. Instead, the instruments use a cylindrical control tube with a conical groove along its axis. The flow switch can be used for continuous control of fluids and gases to ensure that excess or low flow cannot result in damage to the equipment. Applications can be found wherever it is necessary to control flow reliably.
