RMG series includes radar level transmitters. The level of liquids is measured by transmitting low energy radar pulses towards the liquid surface and receiving the radar echoes. The travel time for the radar pulse is proportional to the distance between the gauge and the surface. Upon reception, microprocessors and intelligent software in the gauge head analyze the echoes and transform them into level output data. The radar pulse is unaffected by the tank content and atmosphere, temperature or pressure. Thus, radar measurement is proven to be the most reliable gauging method in most applications. Furthermore, maintenance requirements are not to be considered as no part of the gauge is in physical contact with the liquid.
