Measuring range
Measuring Range and Minimum
Dielectric Constant
16 in. (0.4 m) to 164 ft (50 m)
See Table 8 on page 44 for each probe’s measuring range and minimum dielectric constant.
Due to the measuring range depending on the application and factors described below, the
values are a guideline for clean liquids. For more information, ask your local Emerson Process
Management representative.
Different parameters (factors) affect the echo and therefore the maximum measuring range
differs depending on application according to:
 Disturbing objects close to the probe
 Media with higher dielectric constant (e
r
) gives better reflection and allows a longer
measuring range
 Surface foam and particles in the tank atmosphere may affect measuring performance
 Heavy coating or contamination on the probe should be avoided since it can reduce
measuring range and might cause erroneous level readings
Note
For Remote Housing, see Table 9 on page 45 for the maximum recommended measuring range
for different Remote Housing lengths, installation types, Dielectric Constants, and probe types.
