Abstract
An material level monitoring and reporting system uses special micropower impulse radar level sensing probes, with one such probe being inserted into each of a plurality of material containment structures, such as storage tanks. The micropower impulse radar probes use flexible waveguides which extend downward to the tank bottom such that micropower radar impulses travel to and from the liquid surface via a wave guide, with the lapse between emission and reception of the impulse indicating a distance from the probe, and thus a liquid level. Each level sensing probe is connected to a communication link which collects level and status information from the level sensing probes and transmits it to a monitoring site. The material level data may be collected from a plurality of intermediate monitoring sites by a central monitoring sites.
