RG7 measures the level by transmitting radar pulses towards the object and receiving its echoes. The level is determined by the pulses travel time that is proportional to the distance between the sensor and the object surface.
MEASURING PRINCIPLE
Upon reception, the microprocessor that runs the intelligent software in the sensor head analyzes the echoes, transforms them into the surface level values, and outputs the data. Since the radar pulses are minimally affected by the tank content and its environment like temperature and pressure, radar measurement is proven to be the most reliable gauging method in most applications.
BEAM ANGLE
Additionally, because the radar sensor is not physically contacting with the measured object, maintenance of the sensor is extremely minimal.

APPLICATIONS
RG7 is very capable of measuring both calm surface liquids such as storage and buffer tanks as well as very uneven, disturbed surface liquids such as reactor tanks. It is applicable over a wide range of industrial applications including:
* Chemical and petrochemical
* Refinery
* Pharmacy
* Food and beverage
* River intake gate
* Process in waterworks
* Water reservoir
* Waste water treatment plant
* Hydraulic power station
* River and dam
* Coolant pit in steel process
