摘要： Method for fastening an air flow measuring sensor to a duct (1) of a ventilation system, in which method at least one sensor part (2, 3) comprising a measuring sensor or measuring sensors is fastened to a fastening point (4) formed on the outer surface of the duct, which fastening point is made to have a planar surface, and the bottom surface of which sensor part (2, 3) is fastened tightly to the planar fastening point (4). The invention is implemented in such a way that holes (6, 7, 8) are made in the planar fastening point (4) for the sensors.

摘要： Apparatus and method for measuring air flow in a duct, e.g. in a ventilation duct (300), which apparatus comprises a sensor fittable into connection with the duct, the sensor comprising an ultrasound transmitter and at least two ultrasound receivers, and a control unit to which the ultrasound transmitter and ultrasound receivers are connectable. The control unit is adapted to measure, during the measuring of air flow, the phase difference of an ultrasound signal received at the same moment in time by at least two ultrasound receivers fitted into connection with the duct and, based on the measured phase difference, to determine the flow velocity and/or flow direction of the air. The apparatus is adapted to perform a calibration of the apparatus by transmitting with an ultrasound transmitter (100) at least one calibration signal and by receiving the calibration signal with at least two ultrasound receivers (102, 104). The apparatus is further adapted to analyze the received calibration signal and based on the analysis to select the parameters to be used in measuring to be such that at least one analysis result of the calibration signal meets predetermined criteria with the parameters.

摘要： (Apparatus and method for measuring air flow in a duct, e.g. in a ventilation duct (300). The apparatus comprises a sensor fittable into connection with the duct at a certain distance from an interference source, the sensor comprising an ultrasound transmitter (100) and at least two ultrasound receivers (102, 104), and a control unit (304) to which the ultrasound transmitter and ultrasound receivers are connectable. The control unit is adapted to measure the phase difference of the ultrasound signal received at the same moment in time by at least two ultrasound receivers (102, 104) fitted into connection with the duct and, based on the measured phase difference, to determine the flow velocity and/or flow direction of the air. The control unit is adapted to compensate the determined flow velocity and/or flow direction of the air with a coefficient that is formed on the basis of the diameter of the duct, the type of interference source and the distance between the sensor and the interference source.

摘要： Apparatus and method for measuring air flow in a duct, e.g. in a ventilation duct (300), which apparatus comprises means, connectable to the control unit, for measuring the flow velocity and/or the flow direction of the air in the duct. The apparatus further comprises means, arranged in connection with the duct, for measuring distance. The apparatus is adapted to measure the size of the duct, or of a part of the duct, with the means for measuring distance. The apparatus is further adapted to record and/or to send information relating to the size of the duct to an apparatus, to a control unit and/or to a control unit connectable to an apparatus.
