摘要： This sensor (10) generates accurate measuring results, for example with an error in the order of 0.5% of the measuring value, hat has mimimized production costs as well as a shorter overall length compared to that of conventional sensors. The sensor has two parallel V shaped measuring tubes (1, 2) each being of one-piece construction. Each tube has a straight inlet portion (11, 21), a straight outlet portion (12, 22), an inlet bend (13, 23) connected with the inlet portion, an outlet bend (14, 24) connected with the outlet portion, a straight tube portion (15, 25) connected with the inlet bend, a straight tube portion (16, 26) connected with the outlet bend, and a vertex bend (17, 27) connected with the first and second straight tube portions. The inlet portions (11, 21) are fixed in an inlet manifold (18) and the outlet portions in an outlet manifold (19); the manifolds (18, 19) are mounted in a support frame (30) which forms part of a housing (3). An excitation arrangement (6) causes the measuring tubes (1, 2) to vibrate as a tuning fork. Interspaced sensor elements (7, 8) are fixed to the measuring tubes. Mounted in the support frame (30) is a feedthrough (37) for a printed-circuit board (96) having conducting tracks (97) to which leads (63, 64, 73, 74, 83, 84) of the excitation system (6) and of the sensor elements (7, 8) are connected.

The Coriolis mass flow/density sensor includes a measuring tube, an excitation arrangement for exciting the measuring tube to vibrate in a second fundamental flexural mode of vibration; and a counterbalance member attached to the measuring tube which counterbalances the vibration of the measuring tube. A cantilever can be attached to the measuring tube midway between the inlet end and the outlet end of the measuring tube. First and second sensors sense the measuring tube vibration on the inlet and outlet sides of the measuring tube, respectively.

摘要： This mass flow/density sensor (10), which can be installed in a pipe and through which a fluid to be measured flows during operation, is to be balanced over a wide density range, so that accurate measurements are possible. A single straight measuring tube (13) having a longitudinal axis (131) extends between its inlet end (11) and the outlet end (12) and is fixed to a support, e.g., a cylindrical tube (14, 14'). The support has a longitudinal centroidal line (141) which is parallel to, but does not coincide with, the longitudinal axis (131) of the measuring tube. A cantilever (15) is fixed to the measuring tube (13) midway between the inlet and outlet ends (11, 12) and in operation causes the measuring tube to vibrate either in a first fundamental flexural mode or in a second fundamental flexural mode having a higher frequency than this first mode. An excitation arrangement (16) disposed midway between the end pieces excites the measuring tube (13) in the second mode. Sensors (17, 18) for the motions of the measuring tube on the inlet and outlet side are positioned between the middle of the tube and the inlet and outlet ends, respectively. The support may be provided with a counterbalance. Because of the torsional vibrations exerted by the cantilever on the measuring tube, the sensor is also well suited for measuring the viscosity of the fluid.

摘要： A method for signal processing of measurement signals of a vortex flow transducer for measuring flow of a medium through a measuring tube. The method is characterized by low needs as regards computing power and memory space. The transducer includes a bluff body arranged in the measuring tube and a sensor for registering pressure fluctuations arising at the bluff body and for converting such pressure fluctuations into an electrical measurement signal. In the method, at least a portion of the measurement signal is sampled and digitized, an autocorrelation of the digitized measurement signal is calculated, and the flow is derived on the basis of at least one characteristic of the autocorrelation.
