Abstract: A method for determining a cathodic current (such as from a cathodic protection system) in a tubular disposed within a wellbore drilled in a subterranean zone. A electromagnetic tool disposed within the tubular includes an electromagnetic transmitter, an electromagnetic receiver, a helical transmitter coil, and a helical receiver coil. An axis of the helical transmitter coil and an axis of the helical receiver coil are substantially parallel to an axis of the tubular.

During the transmitting, an electromagnetic signal is received by the electromagnetic receiver via the helical receiver coil. A second electrical current is calculated based on the electromagnetic signal received by the electromagnetic receiver. A magnitude of the cathodic current flowing through the tubular is calculated based on a difference between the first electrical current and the second electrical current.

Abstract: A chemical dispensing mechanism detects the liquid surface of a chemical including a chemical container mounted on a chemical disk. A calculation control unit controls the operation of the chemical dispensing mechanism. The calculation control unit performs a first raising operation, in which a chemical stored in the chemical container is suctioned by the chemical dispensing mechanism, which is then raised up to a first bubble detection position, determines whether a liquid surface is present, and outputs an alert indicating the presence of a bubble on the liquid surface when the liquid surface has been determined to be absent. The first bubble detection position is when the tip of a dispensing nozzle of the chemical dispensing mechanism remains inside the liquid when there are no bubbles present on the liquid surface, and is exposed from the inside of the liquid when there are bubbles present on the liquid surface.

Abstract: A method operates a measuring device used to determine a fluid variable. The measuring devices contains a vibration transducer driven to excite a wave in the fluid due to a test excitation signal. The wave is guided along a propagation path back to the vibration transducer or to an additional vibration transducer, thereby exciting the (additional) vibration transducer to vibrate. An output signal relating to this vibration is acquired, and a frequency of that segment of the output signal that lies in an analysis interval is determined. The analysis interval starts once the driving of the vibration transducer to excite the wave has finished, and/or once a maximum of the amplitude of the vibration is reached. The determination of the fluid variable is performed based on the determined frequency. An error message or a notification is output to a user and/or to a device external to the measuring device.

Abstract: Methods, systems, and computer-readable storage media for accurate time delay estimation using coherent averaging. A plurality of out-of-bracket acoustical impulses are generated in a pipe segment of a fluid distribution system. Signal data representing the acoustical impulses sensed at two locations along the pipe segment are recorded. Precise timings for the generation of the acoustical impulses are obtained, and the acoustical impulses in the signal data recorded from the first location are averaged based on the precise timings to produce a near-sensor average impulse. Similarly, the acoustical impulses in the signal data recorded from the second location are averaged based on the same precise timings to produce a far-sensor average impulse. A time delay between arrival of the plurality of out-of-bracket acoustical impulses at the first and second locations is estimated from the timing of the near-sensor average impulse and the far-sensor average impulse.
