Abstract: A system for testing a rheological behavior of a slurry comprises a first stirring reactor, a second stirring reactor, a material supply pipe, a driving device, and a pressure detection member. The driving device has a first state and a second state. In the first state, the driving device drives a slurry in the first stirring reactor to be outputted to the second stirring reactor. In the second state, the driving device drives the slurry in the second stirring reactor to be outputted to the first stirring reactor. The pressure detection member is used to measure a pressure level in the material supply pipe.

Abstract: Provided herein are portable apparatus as well as methods of analyzing an injection fluid using these portable apparatus. In some embodiments, the injection fluid can contain a polymer, but a polymer is not necessary. For example, the portable apparatus and methods may be used to determine viscosity, long term injectivity, filter ratio, or any combination thereof of the injection fluid.

Abstract: Methods and systems for detecting deposit buildup within an ultrasonic flow meter are disclosed. At least some of the illustrative embodiments are ultrasonic flow meters comprising a spool piece configured to couple within a flow of fluid, a first transducer pair mechanically mounted to the spool piece and configured to fluidly couple to the flow of fluids (wherein the first transducer pair comprises an upstream transducer and a downstream transducer in operational relationship to the upstream transducer and defines a first chord there between), and electronics electrically coupled to the first transducer pair. The electronics is configured to detect deposit buildup over an inner surface of the ultrasonic flow meter.

Abstract: A portable apparatus and method for demonstrating different characteristics of different fluids that includes different fluid sumps or chambers for receiving samples of the different fluids. A test shaft having different portions that are immersed in the different fluid samples in the chambers is driven by an electric drive motor at a substantially constant speed while substantially the same amount of friction or force is applied to the different portions of the test shaft at different times to increase the resistance presented to the drive motor. The additional amount of current drawn or power absorbed by the motor or strain induced in the motor drive shaft during the application of such friction or force to the different portions of the test shaft is monitored and compared to provide a comparison of the friction or power loss characteristics of the different fluid samples.

Abstract: A method for measuring interface levels between fluids is described, characterized in that, with the aid of a magnetic field forming means, a variable magnetic field is formed in one of the fluids whereby a counterflowing magnetic field is established, being a function of the fluid properties with respect to the portion of conducting fraction in the fluid, and conductivity of the fraction; and the properties of the mentioned fluid are registered by registering the dominating impedance, alternatively resonance frequency, of the system; and by corresponding registrations of different fluid layers at the respective height levels, and in the existing interphase layers, and thereafter by mutual comparison of the mentioned properties, one or more exsisting multiphase levels are determined. A device to carry out the method is also described.

Abstract: A device which may be carried by and part of an unmanned vehicle which measures characteristics of manure of animals such as dairy cows that are milked and fed in a stable provided for them. The vehicle is supported by three driven wheels and carries a mechanism for analyzing manure which comprises a compression chamber for receiving a manure sample. A sieve is provided on one side of the chamber and a piston forces the manure sample through the sieve. By measuring the pressure required to squeeze the manure sample through the sieve, characteristics such as the fibrousness and the viscosity of the manure sample can be determined. The vehicle also carries an identification instrumentality for identifying the animal that provided the manure sample and may carry a temperature sensor and an inertia meter. It is operatively associated with a computer which registers data provided from analysis of each animal's manure sample and provides same as displayable data.
