Evac provides a wide range of Sensors, which ensures a consistently high degree of accuracy of Measurement. Evacs Sensors have been developted for high resistance to pollution especially remains of toilet tissues. Displays, which provide a numerous configuration options, tailored to meet individual requirements. Buttons with a wide range of display possibilities, extremely robust, flexible in application and easy to operate.
Liquid Level Guard
Evac’s newly developed liquid level guard represents the state of the art in measuring technology. Made of stainless steel, it is robust, cost-efficient and extremely precise. By measuring fresh, grey and waste water levels electronically instead of mechanically, it is both more exact and fault resistant than conventional devices. Paper, incrustrations and other deposits are ignored during the measurement process. Real-time electronic transmission of the generated data allows to trigger active countermeasures (e.g. against blockages), and additional data can be used to support preventive and condition based maintenance.
