Updating firmware on a ULM-53 level meters

From June 13, 2011 we began to supply the level meters ULM-53 with updated firmware. Compared to the previous version the ULM-53 level meters have a faster response to changing level and reduced sensitivity of random disturbing reflections. Their output is more stable in turbulent surface. In addition, they are complemented by the function "factory default" (default setting).More information can be found in the technical documentation.
