14.4.2 Response time

The response time depends on the configured application parameters.
Minimum values:

Two-wire version: ≥ 3 s

14.4.3 Measured value resolution

2 mm (0.08 in)

14.4.4 Measuring error

Better than ±4 mm (±0.16 in)or 0.2 % of the measuring distance, the larger value applies
Observe typical measured error under reference operating conditions

• Linearity

• Reproducibility

• Hysteresis

14.4.5 Maximum measured error

According to EN 61298-2; under reference operating conditions
±0.2 % in relation to the maximum sensor span

14.4.6 Influence of gas phase

The vapor pressure of the medium at 20 °C (68 °F) is an indicator of the accuracy of the

ultrasonic level measurement.

Accuracy

Very good accuracy: vapor pressure at 20 °C (68 °F) less than 50 mbar (1 psi). This applies

for:

• Water

• Aqueous solutions

• Water/solid solutions

• Diluted acids, e.g. hydrochloric acid, sulfuric acid

• Diluted bases, e.g. sodium hydroxide solution

• Oils, greases, lime water, sludges or pastes
Accuracy impacted: high vapor pressures or outgassing from media, e.g.:

• Ethanol

• Acetone

• Ammonia

Please contact the sales organization if the accuracy is affected.

14.5 Environment

14.5.1 Ambient temperature range

–40 to +80 °C (–40 to +176 °F)
The functionality of the LCD display is limited at Tu < –20 °C (–4 °F) and Tu >

60 °C (140 °F)

If operating outdoors in strong sunlight, use a weather protection cover. Can be

ordered as an accessory.
