Tokyo Keiki Non - Contacting Radar Level Gauge KRG-10

Radar Level Gauge KRG-10

KRG-10 measures liquid level by transmitting low energy radar pulses toward 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.
