Vega Pulse-echo Sensor

Vega Ultrasonic Level Measurement (VEGASON) 
Measuring principle 
- Short ultrasonic impulses in to range of 10 to 70 kHz are emitted by the transducer to the measured product, reflected 
by the product surface and received again by the transducer. They spread with sound velocity. The time from emission to reception of the signals is 
proportional to the level in the vessel. The proven ECHOFOX signal processing filters out the correct level echo reliably from a number of false reflections. 
An adjustment with empty and full vessel is not necessary! 
Applications in liquids 
- Sensors with frequencies between 30 and 70 kHz are used for these applications. They operate independent of 
product properties and are ideal for water/waste water applications and the measurement of slightly corrosive acids and lyes. Also applications in 
gas-Ex areas can be equipped with these sensors. 
Applications in bulk solids 
- Sensors with frequencies between 10 to 30 kHz are used for these applications.
