Non hygienic level measurement of liquids where a flush diaphragm is needed. Examples are water, wastewater and oil. Because of the flush diaphragm very suitable for liquids which can cause clogging like pulp, paper and starch. For the pulp and paper industry specific process connections are available. Weight measurement in tanks with linearisation in Tons.
