Publication number: 20230243681Abstract: A throughflow measurement system comprises a measurement body that has an inlet flange, an outlet flange and a fluid passage, wherein the fluid passage has a passage axis; an ultrasonic measurement apparatus integrated into the measurement body; and a flow conditioner arranged upstream of the ultrasonic measurement apparatus in the fluid passage. An arrangement of bores for fastening means is provided at the outlet flange, wherein an axially extending outlet fastening region of the measurement body is defined by the length of the bores. The ultrasonic measurement apparatus has at least one reflection measurement path that is spanned by a first ultrasonic transducer, a reflector and a second ultrasonic transducer and that extends in a measurement plane through the fluid passage such that the second ultrasonic transducer is arranged downstream of the first ultrasonic transducer. The second ultrasonic transducer disposed downstream is arranged in or projects into the outlet fastening region.Type: ApplicationFiled: January 27, 2023Publication date: August 3, 2023Inventors: Gerry SCHRÖTER, Mario KÜNZELMANN, Eric STARKE, Christian SCHULZ

Patent number: 11385085Abstract: An ultrasonic flowmeter comprising a conduit in a support housing and at least two ultrasonic transducers in a measuring insert which can be inserted into the support housing and the conduit perpendicularly to the conduit. The conduit comprises a circular cylindrical receptacle with a diameter larger than the inside diameter of the conduit and a depth encompassing the inside of the conduit, for inserting the measuring insert into the conduit perpendicular to the flow direction. Four ultrasonic transducers are provided in a wall of the measuring insert, the transducers define at least two measuring paths which cross each other in top view. The transducers are arranged in the measuring insert wall such that ultrasonic signals emitted and received by the ultrasonic transducers on the measuring paths have a transit time difference th?tr dependent on the flow velocity v and/or the flow rate Q of a fluid flowing in the conduit.Type: GrantFiled: June 24, 2020Date of Patent: July 12, 2022Assignee: SICK ENGINEERING GMBHInventor: Gerry Schröter

Patent number: 10571320Abstract: A measurement apparatus (10) and to a method provide for the determination of a flow rate (v) and/or of a throughflow (Q) of a fluid (14) flowing in a conduit (12). At least one first ultrasonic transducer (18) and one second ultrasonic transducer (20) permit a flow rate determination via the time of flight of an ultrasound signal. To further improve the determination of a flow rate of a fluid using ultrasonic transducers, in particular at very high flow rates, and to enable the measurement of very high flow rates, a noise-measuring ultrasonic transducer (18, 20; 24) is provided that measures the noise generated in on the flowing past of the fluid (14) in the ultrasonic transducer, and a control and evaluation device (32) is configured to determine the flow rate (v) using the noise measurements.Type: GrantFiled: February 21, 2018Date of Patent: February 25, 2020Assignee: SICK ENGINEERING GMBHInventors: Ekkehard Riedel, Gerry Schröter, Toralf Dietz

Patent number: 6904811Abstract: A flow meter, such as a gas meter, for measuring the flow velocity and/or the volumetric through-flow of fluids. The flow meter has a body with connecting flanges for connecting the meter to a pipeline for the fluids. The meter has a tubular center piece that, on its exterior, has at least two receptacles, each of which receives a measuring device. The measuring devices are coupled to a signal processing unit. Electrical cabling between the measuring devices (probes) and the signal processing unit is completely covered against damage from the exterior by partially guiding the cables through bores in walls of the center piece of the flow meter and by covering portions of the cable and protruding sections of the probes with a cap.Type: GrantFiled: September 13, 2002Date of Patent: June 14, 2005Assignee: Sick AGInventors: Andreas Ehrlich, Gerry Schroeter

Patent number: 6895824Abstract: A body for a flow meter for measuring the flow velocity and/or the volumetric through-flow of fluids. The flow meter body has a tubular center piece with connecting flanges for connection to a pipeline for fluids. On its exterior, the center piece has at least two substantially flat mounting surfaces (18, 20, 22, 24), each of which has at least one receptacle (32, 34; 38, 40, 42, 44) for mounting a probe (35). To enable the use of linearly emitting ultrasound probes in such flow meters, and to use the flow meter as a substitute for prior art flow meters without significant effort and cost, it is proposed to arrange the mounting surfaces (18 and 20; 22 and 24) diametrically opposite each other as a mounting surface pair (18-20; 22-24) so that the probes (35) in the opposing mounting surfaces (18 and 20; 22 and 24) define a measuring path (36, 46, 48). The mounting surfaces (18 and 20; 22 and 24) are parallel to each other and at an angle to a longitudinal axis (26) of center piece (12).Type: GrantFiled: September 12, 2002Date of Patent: May 24, 2005Assignee: Sick AGInventors: Andreas Ehrlich, Gerry Schroeter
