Equipped with heavy-duty stainless steel housing, it is designed to withstand the roughest conditions on ships. If necessary, the signal converter of the level transmitter can be replaced during cargo operations. The Drop antenna option makes it ideal for measuring sticky/contaminating liquids or dust-laden atmospheres where product build-up is likely to occur.
