Endress+Hauser Proline Prowirl 73 - Sample Values for Temperature, Density, Expansion Coefficient

Description of device functions Proline Prowirl 73
158 Endress+Hauser
11.16 Sample values for the functions: TEMPERATURE
VALUE, DENSITY VALUE and EXPANSION
COEFFICIENT
The calculation of the density for user-defined liquids (ä 145) is better the closer the operating
temperature is to the particular value in the "Temperature value" column. If the operating
temperature deviates greatly from the value in the "Temperature value" column, the expansion
coefficient should be calculated as per the formula on ä 150.
