The MRG-10 measures liquid level by transmitting low energy radar pulses toward a liquid surface and receiving the radar echoes.

The radar pulse is virtually unaffected by the contents and atmosphere of the tank, temperature or pressure. Thus radar measurement is proven to be the most reliable gauging method in most applications. Furthermore, maintenance requirements are practically zero because no part of the gauge is in physical contact with the liquid.
These features make the MRG-10 very well suited for storage and buffer tanks in the chemical and water industry.

The MRG-10 is most appropriate for calm liquid surfaces. If you intend to use the MRG-10 to measure turbulent surface liquids, it may be recommended to employ a still pipe used in order to achieve a calm surface.

The MRG-10 is appropriate for storage tanks or buffer tanks that have relatively calm surfaces.
