An ultrasound flow meter includes a housing (1) which includes a channel (2) for leading through a fluid, which fluid flow rate is to be measured. Two ultrasound transducers are arranged on the wall which delimits the channel (2), within the housing (1). The ultrasound transducers are fixed within the housing by a non-releasable snap connection and/or clamping connection.

A detection device for fluid is provided. The detection device is configured to detect fluid flowing in a transparent tube. The detection device includes a main body, a light emitter, a mirror, a plurality of light receivers and a control circuit. The main body covers the transparent tube and includes a first surface and a second surface opposite to each other. The light emitter is arranged on the first surface and emits a first light beam toward the second surface. The mirror is arranged on the second surface to reflect the first light beam into a second light beam. The light receivers are disposed on the first surface to receive the second light beam and convert it into a first signal. Each of the light receivers is connected in series. The control circuit is electrically connected to the light receivers, and processes the first signal output by the light receivers.

Also disclosed is a method of optically measuring fluid flow rate in a fluid processing system including optically monitoring fluid flow through a transparent portion of a tubing by measuring light reflectance of particles in the fluid.

A flow metering system includes a flow meter coupled to a plurality of sensors and configured to measure volume of fluid flowing through the flow meter. The system also includes a metrology computer coupled to the flow meter and the sensors. The metrology computer is configured to receive live values from a plurality of sensors during a first time period, train an artificial intelligence engine based on the live values received during the first time period, and detect a sensor failure based on a deviation between a live value from the sensor and a predicted value for the sensor. The predicted value is based on live values from other of the plurality of sensors and the artificial intelligence engine.

The invention relates to a method for determining the absolute value of the flow velocity (v) of a particle-transporting medium. At least two measurement laser beams (L_i) with linearly independent, non-orthogonal measurement directions (b_i) are emitted. The measurement laser beams (L_i) scattered at particles are detected and one measurement signal (m_i) is generated in each case for each measurement laser beam (L_i). The measurement signals (m_i) are evaluated, wherein absolute values of velocity components (v_i) are ascertained as projections of the flow velocity (v) on the respective measurement directions (b_i), wherein a solid angle region is ascertained for the prevalent direction of the flow velocity (v) and signs assigned to this solid angle region are chosen for the individual velocity components (v_i), and wherein the absolute value of the flow velocity (v) is determined using the ascertained absolute values of the velocity components (v_i) and using the chosen signs for the velocity components (v_i).
