Product Description
The RHEONIK transmitter contains two tube loops outlining the shape of a tennis racket(OMEGA), fluid flow direction being the same in both loops. These loops form part of an oscillating system which also includes two horizontally mounted crossbars and two vertically mounted torsion rods. The torsion rods are connected together on both ends. The natural frequency of the oscillating system depends mainly on the mass of the cross bars and the modulus of elasticity of the torsion rods. This oscillating system is exicted by electromagnetic coils with a controlled amplitude, the resulting oscillation being sensed by a pair of pick-up coils.
Since this system is symmetrical, internal acceleration forces are counterbalanced. The measuring section of the loop and its movement is stabilized by two torsion rods and cross bars, resulting is the measuring section(a-b) being kept free of any external influences such as vibration which could affect performance.
This tube section(a-b) makes its oscillating movement upon an imaginary disc, wherepoint a and b are positioned on the circumference.
Measured mass starting at "a" moving on the "oscillating disc" towards "b" passes orbits of different velocities. An additional force(Coriolisforce FC) acting in the plane of the disc, perpendicular to the movement of mass on the disc(a-b), is directly proportional to mass-flow. This force causes an additional deflection of the tubes and is sensed as a phase difference between the outputs of the two pick-up coils.
