  • Patent number: 10724882
    Abstract: A thermal flowmeter comprises a heating element thermally coupled to a flowing medium, a first temperature sensor and second temperature sensor. The first temperature sensor detects a flowing medium temperature in a region not affected by the heating element. The second temperature sensor detects a temperature of the heating element and also serves as a heating element. A control unit controls heating power of the heating element based on the difference between the detected temperatures at a predetermined time. The control unit provides a square wave signal to the second temperature sensor so that in a high phase it acts as heating element and in a low phase as a temperature sensor.

  • Patent number: 10718677
    Abstract: The pressure sensor comprises the diaphragm, an electrode body, a housing, an inlet pipe, and a thermal buffer member. The diaphragm includes a pressure receiving surface configured to receive a pressure of a measured target fluid. The electrode body includes an electrode surface facing a rear surface of the pressure receiving surface with a gap interposed therebetween. The housing supports the diaphragm so as to form a measuring chamber by surrounding the pressure receiving surface. The inlet pipe is coupled to the housing and configured to guide the measured target fluid into the measuring chamber. The thermal buffer member is disposed on the inlet pipe and has a predetermined heat capacity. Accordingly, the diaphragm is unlikely to bend due to a rapid temperature change in a fluid guiding pipe disposed a fluid line.

  • Patent number: 10690560
    Abstract: Methods and apparatuses for indicating the presence of a threshold directional differential pressure between separated adjacent spaces. A conduit contains a movable element that indicates whether the pressure difference between the two spaces is at least as high as a threshold pressure difference. The apparatus is adjustable to have different threshold set points by adjusting the pivot arm inclination. The device may include at least two pivot axes. A rotating base may rotate relative to the barrier or wall, and a pivot arm may be attached and rotate relative to the rotating base. With the rotating base set at a first rotation angle, the pivot arm may be adjustable within a single plane. When the rotating base is set at a second rotation angle, the pivot arm may be adjustable within a different single plane. The device may include a single pivot axis where a pivot arm is parallel to the wall and rotates about a horizontal axis perpendicular to the wall.

  • Patent number: 10690529
    Abstract: Ultrasonic measurements are made of a multiphase fluid (oil, water and gas) in pipe or conduits with high values of gas content in the multiphase fluid. Ultrasonic transceivers are positioned around the pipe wall in acoustic contact with the fluid system. The fluid flow is caused to move in a vortex or swirling flow with vortex inducing elements located in the pipe upstream of the transceivers, forcing the gas phase to a cylindrical area at the center of multiphase flow in the pipe, with water and oil multiphase fluid components forming an outer annular flow. Measures of cross sectional composition of the gas portion of multiphase fluid are provided based on the reflected waves from the interface. Tomographic images of the relative presence and position of the three fluid phases are also formed.

  • Patent number: 10684127
    Abstract: A measuring device (10) has two measuring units (12), (13), each having a probe unit (16), (35). Each probe unit has a probe element (18), (37) having, in a probing direction (x), an outer probe side (18a) or (37a) and an inner probe side (18i) or (37i). To determine a zero position or a reference plane (B) at right angles to the probing direction (x), the two probe elements can be brought into contact via their respective outer probe sides (18a), (37a) or their respective inner probe sides (18i, (37i). As soon as contact between the associated probe sides (18a), (37a) or (18i), (37i) is detected, a reference plane (B) is defined as zero position in the probing direction (x) using the point of contact between the two probe elements. The zero position can thus be determined without calibrated standards or block gauges.

  • Patent number: 10684151
    Abstract: A method includes actuating a pump at a constant nominal flow-rate to induce liquid flow out of a vessel through an outlet duct. The outlet duct communicates with the vessel with an upper aperture at an intermediate level height, and a lower aperture at a reduced level height. Flow of liquid is detected in the outlet duct. A digital signal assumes an alternate sequence of states when the liquid level is between the intermediate and reduced levels. Each state is an air-indicating state or liquid-indicating state. The presence or absence of air bubbles is detected in the flow of liquid. The digital signal is compared with a reference signal having a predetermined sequence of air-indicating states and liquid-indicating states. Pump actuation duration is modified as a function of a difference between the digital and reference signals. An apparatus is controls the supply of a liquid level in a vessel.
