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 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.
