Publication number: 20250216234Abstract: A flow measurement system includes an ultrasonic flowmeter including two or more ultrasonic transducers arranged in flow direction, when the ultrasonic flowmeter is fixed to the channel, and emitting and receiving an ultrasonic pulse in the channel, and a processor connected to the transducers. The processor determines and stores transit times of ultrasonic pulses propagating in and against a flow direction along a path in the channel, and determines a flow of gas using the transit times. The flow measurement system further includes a damper system has a damper blade arranged in the channel downstream of the ultrasonic flowmeter. The ultrasonic transducers receive one or more reflections of an ultrasonic pulse in the channel, and the processor determines and stores transit times of ultrasonic pulses propagating in and against flow direction along one or more reflection paths, and determines the flow of gas using the transit times.Type: ApplicationFiled: March 14, 2025Publication date: July 3, 2025Applicant: BELIMO HOLDING AGInventor: Patrick REISSNER

Publication number: 20240230120Abstract: An air treatment device is disclosed. The air treatment device includes an air duct configured to deliver an air flow. A first filter stage is included and comprises at least one air filter arranged in the air duct for filtering the air flow. At least a second filter stage is also included and comprises at least one further air filter and is arranged downstream of the first filter stage (for filtering the air flow after having passed the first filter stage. The second filter stage is controllable between at least two states with different filtration efficiencies, whereby, with respect to a filtration efficiency in the first state, a filtration efficiency in the second state is lower, in particular the filtration efficiency in the second state is essentially zero. An air quality sensor is also present, the sensor allowing for measuring the air quality of the air flow in between the first and the second air filter stages.Type: ApplicationFiled: February 24, 2022Publication date: July 11, 2024Applicant: BELIMO Holding AGInventors: Patrick REISSNER, Roman WYSS
