System for determining rheological properties of grease, includes a grease worker having a cylinder intended to contain the grease and a piston intended to move inside the cylinder in a first direction and in a second opposite direction and provided with holes. The grease worker further including a seal provided between the piston and the cylinder, force for measuring the force required to push the grease through the holes of the piston is measured an electrical motor and an eccentrical connection transforming the rotating motion of the motor in a translation motion pushes the grease thought the holes, a thermocouple for measuring a temperature of the cylinder, a fan and a heater for regulating temperature for maintaining constant the measured temperature at a predetermined temperature, and a computing unit configured to determine at least one rheological property of the grease from the measured forces and from the seal friction.

A system and related method for precisely monitoring fluid or gas flows, comprising: a flow meter comprising a mechanical metering component; the mechanical metering component comprising a ferrous material; a three-axis magnetic field sensor for sensing fluctuations of a magnetic field arising from movements of the ferrous material, and specifically, for sensing a magnetic field vector of the magnetic field; computer processing for receiving data from the magnetic field sensor and storing magnetic field behavior data representing time behavior of the magnetic field vector in three space dimensions; calibration programming for analyzing and learning a magnetic signature of the meter; programming for storing a unique calibration pattern of the magnetic signature representing baseline behaviors thereof; and comparison programming for comparing behaviors of the magnetic field during operation with the calibrated baseline behaviors and thereby deducing flows which are occurring during operation as a function of time under various conditions.

A device measures the flow rate of a fluid, such as concrete, in a pumping plant connected to a drilling machine provided with a drilling tool. The pumping plant includes a motor pump and a connection pipe to lead fluid from the motor pump to the drilling tool. The device includes a transmitting module, for rigidly and removably mounted on the pumping plant and including an accelerometer and a receiving module, associated with the drilling machine. The transmitting module detects accelerations generated by vibrations of the pumping plant during the pumping of the fluid. The accelerations indicate flow rate of the fluid. The transmitting module wirelessly sends a signal, which is processed based on the detected accelerations, to the receiving module. The receiving module receives the signal from the transmitting module and sends a signal indicating the flow rate of the pumped fluid based on the received signal.

A handheld fluid meter includes a cartridge valve controlling the flow of fluid through the handheld meter. The cartridge valve includes a valve cartridge and a valve stem disposed within the valve cartridge. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The overmolded stem tip is a compliant material. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.

A system and method (i.e., utilities) for calculating, in substantially real-time, the thickness of marking materials applied to roadway surfaces. The utilities utilize a linear position sensor to monitor positions of a shaft of a positive displacement paint pump. By monitoring the shaft position multiple times per stroke of the pump, pump displacement volumes may be calculated for intra-stroke movements of the pump. The pump displacement volumes permit calculating applied thickness of the marking materials in finer temporal increments than was previously possible.
