Abstract:
A material level monitoring system for monitoring a level of a flowable material in a containment structure and comprising:(a) a micropower impulse radar probe positioned in spaced relation to a material surface of a flowable material within said containment structure, said probe being operative to transmit a micropower radar impulse toward said material surface, to receive a reflected micropower radar impulse returning from said material surface, and to calculate material level data from a time lapse between transmission of said impulse and reception of said reflected impulse; (b) a remote monitor device positioned remote from said probe and operable to process said material level data; and (c) a communication link coupling said probe to said monitor device to enable communication of said material level data from said probe to said monitor device, said communication link being a radio frequency communication link including a radio transmitter coupled to said probe and a radio receiver coupled to said monitor device.
