Radar Level Meter
Radar sensors are affected by different variables than other level sensors. Radar level transmitters are affected less by temperature than ultrasonic sensors, improving consistency and accuracy. Radar level sensors are also well suited for specialty applications, such as working in a vacuum, or in higher pressures (as long as the housing can handle it). Radar sensors are also less affected by foam, vapors, powders, and dust that can interfere with signals on ultrasonic sensors and lead to erroneous readings. This can make radar sensors a better choice for these applications.
It has the following distinguishing advantages:
- Non-contact, maintenance-free measurement
- Not affected by medium properties like density and conductivity, in bulk solids also unaffected by filling noise and dust
- Freely adjustable measuring range
- For high temperatures up to +450°C/+842°F
- It affected less by temperature than ultrasonic sensors, improving consistency and accuracy
- Radar level meters are also well suited for specialty applications, such as working in a vacuum, or in higher pressures (as long as the housing can handle it)
Working Principle
The radar level antenna transmits a narrower microwave pulse and is transmitted downward through the antenna. After the microwave contacts the surface of the measured medium, it is reflected back and received by the antenna system again. The signal is transmitted to the electronic circuit and automatically converted into a level signal (because the microwave propagates at a very fast speed, the electromagnetic wave reaches the target and is reflected back to the receiver. The time used is almost instantaneous)
Radar level measurement is a safe solution even under extreme process conditions (pressure, temperature) and vapours. Radar level transmitters can also be used in hygienic applications for non-contact level measurement
Key Feature
- Radar sensors are also less affected by foam, vapors, powders, and dust that can interfere with signals on ultrasonic sensors and lead to erroneous readings
- The reference plane for measurement is: the bottom surface of the thread or the sealing surface of the flange
- When using the radar level timer, make sure that the highest level cannot enter the measurement dead zone (the area shown in D in the figure).
- Perfect for use with corrosive liquids, thick fluids, slurries or other applications where direct contact with the media would not be desired
- Low dielectric feature allows for operations in liquids with dielectric constants of 2 or greater.
- Unaffected by vapors or fumes
- Smart Sensor technology keeps beam narrow
- Low Dielectric Mode for measurement of non-conductive liquids
- Simple configuration via push button or Gateway software
- These are easy to install and low on maintenance as there are minimal or no moving parts.
