The exact values are dependent on the type of device and the parameter settings.
Maximum measuring error
1)
2)
±0.2 % of the maximum span of the sensor
Typical measuring error
Include linearity, repeatability, and hysteresis
Better than: ±3 mm (±0.12 in) or 0.2 % of measuring distance*
* whichever is greater
Influence of the vapor
pressure
The vapor pressure at 20 °C (68 °F) gives a hint on the accuracy of the ultrasonic level measurement. If the
vapor pressure at 20 °C (68 °F) is below 50 mbar (1 psi), ultrasonic level measurement is possible with a very
high accuracy. This is valid for water, aqueous solutions, water-solid-solutions, dilute acids (hydrochloric acid,
sulfuric acid, ...), dilute bases (caustic soda, ...), oils, greases, slurries, pastes, ...
High vapor pressures or outgassing media (ethanol, acetone, ammonia, ...) can influence the accuracy. If
conditions like these are present, please contact your Endress+Hauser sales representative.
1) according to EN 61298-2
2) with reference operating conditions
