Cost effective all-round instrument for level applications in liquids and bulk solids. Two-wire instrument for continuous non-contact level and flow measurement. Process connection: Thread. Temperature: -20 to +60°C (-4 to +140°F). Pressure: +0.7 to +3bar (+10 to +44psi). Maximum measuring distance: Sensor 1½” for liquids 5m (16ft) and for bulk solids 2m (6.6ft), Sensor 2″ for liquids 8m (26ft)and for bulk solids 3.5m (11ft). Blocking distance: Sensor 1½” 0.25m (0.8ft), Sensor 2″ 0.35m (1.15ft). International explosion protection certificates.
Benefits
- Quick and simple commissioning via menu-guided onsite operation with four-line plain text display, 7 languages selectable
- Envelope curves on the on-site display for simple diagnosis
- Linearization function (up to 32 points) for conversion of the measured value into any unit of length, volume or flow rate
- Non-contact measurement method minimizes service requirements
- Installation possible from thread G 1½ or 1½ NPT upwards
- Integrated temperature sensor for automatic correction of the temperature dependent sound velocity

Features
- Non-contact ultrasonic level / distance measurement using the time-of-flight principle (pulse emission → echo return → distance calculated from time & sound velocity).
- Two-wire transmitter version (4-20 mA output) for continuous non-contact level and flow measurement in liquids, pastes, coarse bulk materials.
- Integrated temperature sensor to automatically correct for sound-velocity changes due to ambient/process temperature changes.
- On-site display (in versions) with a four-line plain text menu (seven selectable languages) and diagnostic “envelope curve” of the echo signal for easier troubleshooting.
- Linearization capability (up to 32 points) so the measured distance can be converted to user units (length, volume, flow) via table.
