Measuring Principle - An electromagnetic pulse is transmitted from the ABM sensor. The pulse 5.8 - 26 GHz carrier Frequency travels to the surface being monitored and is reflected off this surface back to the sensor face.
The time of flight is divided in half, and converted to an output current directly proportional to the material level.
In case of low dielectric materials ( r < 10), electromagnetic wave penetrates materials. In this case - Low Dielectric Material has to be on.
The ABM radar is a one echo sensor, it adjusts its power and sensitivity to receive one echo from measured material and to eliminate any false echoes. This feature gives radar extremely narrow radiation beam (like a laser).
This is not offered by any other brands.Features

Liquid Levels Measurement
To monitor liquids with vapors, gases or volatile surfaces. Pick a Radar Unit with the range for your application.
For corrosive applications the Antenna material can be chosen that is compatible with the liquid.
Monitoring Solid Material Levels
To monitor Dusty Solids and Powder materials the higher 26GHz frequency and dual frequencies help to penetrate the dusty atmosphere found in solids level storage vessels, tank & bins.
They are usually larger in size and require the Self Adjusting Tracking Radar for accurate measurement.
Outdoor Flood Monitoring
The Dual Frequency Radar is used to monitor levels of rivers and seas. The radar works even in dry seasons when there is no water in riverbeds.
Oil- Water Non-Contact Radar Interface Detector (RID)
To monitor with non-contact oil-water interface and top of oil. The 4- 20 mA current output shows both levels.
High Temperature Applications
To monitor applications with elevated temperatures Antenna material selection is Important and Special Mounting De-coupler design with Thermal isolation is required.
Temperature in environment does not effect the ABM Radar performance. For very high temperature (above 200°C) horn with bottom flange is recommended.
Monitoring sanitary applications with Sanitary Ferrule Mounting Food Grade Antenna‘s are available. For the food industry the Antenna must withstand steam cleaning and be quickly removable and easily re-installed.
Explosion Proof Applications
For Measurement in areas Classified as Hazardous (Class I Div. I) such as Gases, Petrochemical, Vapors and Dust. These Areas require containment of Atmosphere.
Crane Anti-Collision Systems
To maintain a safe working distance between two cranes operating on same track.
Fuel Efficiency for Ship Applications
Measurement of wave profiles, to control optimal vessel trimming.
Contact Level Measurement
For contact liquid measurement the ABM Radar with metal pipes, aircraft cable or rods is offered ask technical support for drawings and pictures.
