The technical solution relates to measurement technology and is intended for measuring the dielectric permittivity and moisture of highly conductive loose, paste-like and fluid materials such as saline slurry, anthracite, ore, crude oil and oil sludge. The present method is based on using a sensor configured as a segment of a long transmission line, and involves feeding a high-frequency probing signal from a generator that is swept through a range of frequencies to an input of the sensor, and measuring harmonic frequencies at which a length of a signal conductor of the sensor is equal to or a multiple of a half-wavelength of the probing signal in the material filling the sensor. The harmonic frequencies are determined based on a voltage minimum at an output of a detector configured as a phase discriminator, the output voltage of which attains a minimum when input signals of the detector are either in-phase or antiphase. Inputs of the detector are coupled to an input and output of the sensor via segments of a coaxial cable which have the same electrical length, said segments being matched at the outputs. Designs for a moisture meter for carrying out the above method are proposed. For the purpose of carrying out measurements in pipelines, the sensor is configured as a conduit having the signal conductor arranged therein. For loose materials in hoppers and on conveyor belts, the sensor is configured as a shield which a U-shaped rod is secured to. The technical result is an increase of measurement accuracy.

The present invention relates to systems and methods for automated monitoring of an environment enclosed by a manhole cover having a manhole. The automated monitoring of the environment generally includes obtaining a first reading from a first sensor coupled to a monitoring assembly, transferring the first reading from the first sensor to an Information Processor and Cloud Transceiver (IPCT), processing the first reading from the first sensor in the IPCT to create an output defined as an operating condition of the environment and communicating the operating condition of the environment across a communications network and to a server when the reading is flagged. The monitoring assembly is attached to either an in-flow protector dish or a ring with support brackets, to allow easy installation and removal without concern for the weight of a manhole cover.

Systems, methods, and computer program products for monitoring a level of product (14) in a reservoir (10, 130, 140, 190, 260) of a chemical dispensing system. A lid (22, 148, 216, 302, 358) configured to engage an opening (28, 136, 138, 146, 204, 352) of a container (12, 198, 354) includes a level sensor (26, 244, 272, 342, 386) having a transceiver (36) that transmits an output signal (38) and receives a portion of the output signal (38) reflected back (42) to the transceiver (36). The level sensor (26, 244, 272, 342, 386) determines an amount of the product (14) in the container (12, 198, 354) by comparing a characteristic of the reflected signal (42), such as time the reflected signal (42) was received, to the characteristic of the output signal (38), such as the time the output signal (38) was transmitted. The level sensor (26, 244, 272, 342, 386) may also determine the size of the container (12, 198, 354) based on the reflected signal (42), and take this size into account when determining the amount of product (14) in the container (12, 198, 354). The level sensor (26, 244, 272, 342, 386) transmits product level data to a mobile device (54) in response to receiving an interrogation signal (66) therefrom.

Disclosed is a method for measuring a fill level of a fill substance in a container. The method includes: transmitting a first signal toward the fill substance; receiving a first received signal after reflection of the first signal in the container; transmitting a second signal toward the fill substance, wherein the second signal has at least one defined property deviating from the first signal; receiving a second received signal after reflection of the second signal in the container; ascertaining a first fill level value based on the first received signal and a second fill level value based on the second received signal; and determining the first fill level value or the second fill level value as fill level when the first fill level value and the second fill level value agree. In this way, the fill level is determined in redundant manner.
