  • Patent number: 10962394
    Abstract: A method for measuring a flow of a fluid in a tube includes heating the fluid in the tube with a heating element. A first signal is measured with a first temperature sensing element at a first location. A second signal is measured with a second temperature sensing element at a second location. At least one temperature signal is calculated based on the first signal and the second signal. The at least one temperature signal includes a difference temperature signal and a sum temperature signal. The difference temperature signal is calculated based on a difference between the second signal and the first signal. The sum temperature signal is calculated based on a sum of the second signal and the first signal. The flow is derived based on the difference temperature signal, the sum temperature signal, or a combination thereof.

  • Patent number: 10962459
    Abstract: For measuring rheological properties of a liquid sample, the sample is attached to two sample attachment surfaces opposing each other in a pulling direction. The sample attachment surfaces and the liquid sample attached thereto are arranged in a field of view of a light microscope and imaged onto an electronic camera by means of an objective lens of the light microscope. One of the two sample attachment surfaces is pulled away from the other one in the pulling direction, while a plurality of images of the sample attachment surfaces and the sample attached thereto are registered with the camera. For different distances of the two sample attachment surfaces, both a diameter of the liquid sample in a middle between the two sample attachment surfaces and the respective distances of the two sample attachment surfaces are determined from the images registered with the electronic camera during the step of pulling.
