Ultrasonic Level Measurement
Compact and remote 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
• Flow measurement in open channels and measuring weirs
• System integration via:
– HART (standard), 4…20mA
– Foundation Fieldbus
• Maximum measuring range:
– Up to 70m in bulk materials depending on sensor
Features and Benefits
• Quick and simple commissioning via menu-guided onsite operation with four-line plain text display
• Envelope curves on the on-site display for simple diagnosis
• Easy remote operation, diagnosis and measuring point documentation with the Endress and Hauser software Fieldcare.
• Suitable for explosion hazardous areas
(Gas-Ex, Dust-Ex)
• Linearisation 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
• optional remote display and operation (up to 20 m from transmitter)
• Installation possible from thread G 1½“ or 1½ NPT upwards
• Integrated temperature sensor for automatic correction of the temperature dependent sound velocity
• Relay output options for automatic pump/level control
