Whessoe 1146 is a Level, Temperature and Density (LTD) gauge based on Whessoe´s single body concept. The LTD gauge samples 250 data points to construct a detailed and accurate temperature and density profile. Density and temperature profiles make it possible to detect liquid stratification in the tank. It communicates via dual Modbus ports. The LTD has a local digital display, showing both measured and diagnostic data.
