According to one embodiment, a sensor includes a first member including a first member surface, and a first element part. The first element part includes a first fixed electrode fixed to the first member surface, and a first movable electrode facing the first fixed electrode. The first fixed electrode is along the first member surface. A gap is located between the first movable electrode and the first fixed electrode. The first movable electrode includes a first surface and a second surface. The first surface is between the first fixed electrode and the second surface. At least one of the first surface or the second surface is non-parallel to the first member surface.

A sensor assembly for use in synchronizing seed placement and the dispensing of liquid agricultural product during planting. The sensor assembly includes a signal conditioning circuit configured to provide an output signal representing an indication of the presence of liquid agricultural product and seed for use in determining the synchronization of the seed placement with the dispensing of the liquid agricultural product. The presence of both a seed mass component and a liquid mass component of the output signal defines a package mass. The output signal has a pre-defined value and is transmitted to a controller to determine whether there is an error. The controller is configured to generate an error signal that is capable of being displayable on a remote display/user interface system that can be monitored by the system operator.

A multiphase flow measurement apparatus includes a tubular, a first microwave resonator, a second microwave resonator, and a coplanar waveguide resonator. The tubular includes a wall formed to define an inner bore configured to flow a multiphase fluid. The first microwave resonator has a first helical shape with a first longitudinal length and is configured to generate a first electric field that rotates. The second microwave resonator has a second helical shape with a second longitudinal length different from the first longitudinal length of the first microwave resonator and is configured to generate a second electric field that rotates. The first and second microwave resonators are mutually orthogonal to each other and cooperatively configured to measure a salinity of the multiphase fluid flowing through the inner bore. The coplanar waveguide resonator is configured to generate a third electric field to measure a flow rate of the multiphase fluid.

The present disclosure is related to a free flow electronic meter, which is used in measuring the velocity and flow rate of a fluid, particularly in measuring milk yield of sheep, goat, buffalo and cattle during milking. The free flow electronic meter includes a measurement pipe wherein the velocity of the material that passes through it is measured by means of a flow rate measurement sensor. When the milk flows continuously through the measurement pipe, an air passage pipe and/or free air passage pipe prevents vacuum fluctuation that causes udder diseases. This result is reached by preventing a change of the vacuum level during milking due to increased milk flow at teat end by providing extra air passage.
