However, there are limitations to the types of process they will work in. The factors below\u00a0must be taken into consideration before selecting an ultrasonic level switch for your application.<\/p>\n<ul style=\"list-style-type: square;\">\n<li dir=\"ltr\" style=\"text-align: justify;\"><strong>Liquids only<\/strong> \u2013 the process media must be a liquid. The ultrasonic level switch cannot detect the\u00a0difference between two gases or a gas and a solid. The even density of a liquid is required for\u00a0proper detection.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul style=\"list-style-type: square;\">\n<li dir=\"ltr\" style=\"text-align: justify;\"><strong>Clean liquids only<\/strong> \u2013 a liquid that has too high a percentage of solids will not transmit sound well\u00a0enough to allow detection. Typically 5% suspended solids are the maximum amount allowed.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul style=\"list-style-type: square;\">\n<li dir=\"ltr\" style=\"text-align: justify;\"><strong>The liquid must flow<\/strong> \u2013 an application where the liquid cannot drain out of the sensor gap will\u00a0cause false alarms. If a liquid is too viscous to flow out of a 3\/4\u201d gap then the unit will not\u00a0operate properly. Sometimes this can be solved by different mounting, but some liquids are\u00a0just too viscous.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul style=\"list-style-type: square;\">\n<li dir=\"ltr\" style=\"text-align: justify;\"><strong>No (or few) bubbles<\/strong> \u2013 especially in fluids with a viscosity higher than 100cP (30W motor oil).\u00a0Large bubbles in thick fluids will block the sound signal from crossing the gap. Low viscosity\u00a0fluids can have a fairly large amounts of bubbles as they tend to be very small (Alka-Seltzer in\u00a0water).<\/li>\n<\/ul>\n<p dir=\"ltr\" style=\"text-align: justify;\">If these
