Abstract: A method for fills and/or cleans the measurement cell of a measuring instrument, namely a viscometer and/or density measuring instrument, in particular of a rotational viscometer. A sample is introduced via a sample line into the measurement cell by a pump, and wherein a dynamic viscosity and/or density of the sample is determined in the measurement cell. A funnel-shaped, reversibly openable receiving container, in particular a filling funnel, for the sample, is arranged in the sample line, between the pump and the measurement cell. The receiving container is opened and the sample is introduced into the receiving container. The receiving container is connected to the pump via a pressure line in such a way that, when pressure is applied into the receiving container, a proportion of the sample is dispensed out of the receiving container and introduced into the measurement cell.

Abstract: An apparatus for determining and/or monitoring at least one physical or chemical, process variable of a medium and includes at least one mechanically oscillatable unit and at least one driving/receiving unit. The mechanically oscillatable unit includes a tube and an internal oscillator. The tube is connected to a securement unit with an end turned away from the process and the end of the tube turned toward the process is embodied as a free end. The tube surrounds the internal oscillator and the internal oscillator is secured to the end of the tube turned toward the process with an end turned toward the process. The driving/receiving unit excites the mechanically oscillatable unit to oscillate, respectively it receives the oscillations of the mechanically oscillatable unit. The internal oscillator has at least one groove/neck, which determines at least the oscillation frequency of the mechanically oscillatable unit.

Abstract: The invention resides in apparatus for directly measuring density altitude in an aircraft and includes a housing in communication with ambient conditions of air temperature, pressure and humidity outside the aircraft. A rotor having dynamically balanced blade elements is positioned rotatably within the housing. An electric motor is connected so as to drive the rotor within the housing against the resistance therein of the air under the ambient conditions of temperature, pressure and humidity. An operational characteristic of the motor, such as the current which it draws, is continuously sampled, amplified and changed in shape and applied as the input to a display device which is calibrated to display the input in terms of density altitude.

Abstract: Fluid density is measured in a fluid speed indicating apparatus by using a pair of rotor arms having a pair of asymetrically located venturis or equivalent venturis. A steady state pressure difference will be produced between the two pressure locations and will be a function of the rotational velocity and fluid density. Since the rotational velocity is a known constant, the fluid density can be derived directly from the steady state pressure difference.

Abstract: The present disclosure relates to devices and methods for determining the density of insulation (e.g., in a cavity). For example, one aspect of the disclosure is a device that includes a probe, an actuator, a sensor, and a control system. The control system is configured to cause the actuator to oscillate the probe. The sensor is configured to generate a signal that represents the density of insulation. Another aspect of the disclosure relates to a method for determining the density of insulation. The method includes placing a probe into contact with the insulation, causing, via an actuator, the probe to oscillate while in contact with the insulation, and generating, via a sensor, a signal that represents the density of insulation.

Abstract: A device for measuring the viscosity of the fluid flowing in a closed passage includes a rotor whose speed of rotation is directly dependent on the rate of flow of the fluid. The rotor is connected to an activatable and deactivatable brake means which has an adjustable braking force. Depending on the setting of the brake means, the brake is operative to cause a greater or smaller lag in the rotary speed of the rotor in relation to an unbraked rotor or a rotor braked with a smaller force. The measuring means is operative to determine the resultant different rotational speeds of the rotor and the different in these speeds is a measurement of viscosity.
