ABSTRACT:
A meter is disclosed for measuring water content, particularly of soil. The probe (1) of the measuring device, fed with the needle electric pulse, is constituted of a set of waveguides connected parallely in the embranchment (2) with the microprocessor controller (10) of the electronic assemblies of the measuring device. Waveguides of the probe are installed in chosen layers of the material studied. The directly measured quantity is the sequence of time periods separating subsequent reflections of the electromagnetic wave propagating in the probe from the particular probe impedance discontinuties. The electromagnetic wave propagation velocity in a chosen layer of the medium is calculated on this basis, and therefrom the dielectric constant of the medium, and finally its moisture content upon which the dielectric constant depends.
