摘要： A flash unit that includes a flash generator having at least one energy storage element and at least two light source channels as well as having at least two flash tubes, the flash tubes being supplied with energy by the energy storage element by means of the light source channels. The flash unit further includes an energy quantity control device, by means of which it is possible to provide for each light source channel any desired energy quantity from a minimum charge to a maximum charge of the at least one energy storage element, and a color temperature control device, by means of which it is possible to set a color temperature for each light source channel independently of the energy quantity provided therefor. The functions of all light source channels are fully equivalent.

摘要： To improve both the absolute measurement accuracy and the linearity of the characteristic function and the short-time repeatability of measurements at varying flow velocities, particularly at low flow rates, this electromagnetic flow probe (10) is designed to be immersed in a fluid flowing in a pipe (12), which is to be measured, the direction of immersion being virtually perpendicular to the direction of fluid flow. The probe is further designed to be passed through a hole in a wall of the pipe fluid-tight and comprises a circular cylindrical housing (11) having a predetermined outside diameter adapted to the bore. The front end (14) of the housing extends into the fluid and is closed fluid-tight by a front plate (14") of insulating material in the form of a calotte, which has a radius approximately equal to 1.2 to 1.5 times the outside diameter of the housing. A coil assembly (15) is disposed in the housing for establishing a magnetic field (16) extending through the front plate (14") into the fluid. A coil core (17') is disposed in the housing and made at least partially of soft magnetic material which ends at or near the front plate. A first galvanic electrode (18) and a second galvanic electrode (19) are disposed in the front plate on one of the meridians of the calotte and symmetrically with respect to a vertex of the meridian.

摘要： To permit this flowmeter to automatically operate either on one measurement principle or on another depending on a selectable foreign-particle content of the fluid, it has a first pair of ultrasonic transducers, one of which is operated as a transmitting transducer and the other as a receiving transducer or vice versa, and which are mounted on the outside surface of a fluid-carrying pipe and separated by a given distance in a direction parallel to the axis of the pipe, with the angle between the direction of the ultrasound and the pipe axis differing from 90.degree.. There is provided a second pair of ultrasonic transducers which are operated simultaneously as transmitting transducers or receiving transducers and are mounted on the outside surface of the pipe and separated by a given distance in a direction parallel to the axis of the pipe, the angle between the direction of the ultrasound and the pipe axis being less than or equal to 90.degree.. Driver/evaluation electronics either supply the ultrasonic transducers of the first pair successively with a pulse burst, measure the travel time in the downstream and upstream directions of the ultrasonic signals propagating through the fluid and reflected at the opposite inside surface of the pipe, and determine volumetric flow rate therefrom, or supply the ultrasonic transducers of the second pair with the pulse burst simultaneously, measure the time difference between signals reflected at foreign particles in the fluid and received by those ultrasonic transducers using correlation techniques, and determine volumetric flow rate therefrom. Changeover electronics with a threshold switch switch the driver/evaluation electronics to the travel-time or correlation mode in response to the output of the threshold switch.
