Ultrasonic Level Measurement
Compact transmitters for non-contact level measurement of fluids,
pastes and coarse bulk materials
• Continuous, non-contact level measurement in fluids, pastes, sullages and coarse bulk materials
• System integration via 4 to 20mA
• Maximum measuring range: – 1½" sensor: 5 m (16 ft) in fluids 2 m (6 ft) in bulk materials – 2" sensor: 8 m (26 ft) in fluids 3.5 m (11 ft) in bulk materials
• 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 NPT 1½“ upwards
• Integrated temperature sensor for automatic correction of the temperature dependent sound velocity
