Abstract
A mount for electrical leads to a vibration-type sensor and/or for coils on a vibration-type sensor. The mount includes at least one resilient first arm attached to a first sensing tube of the sensor and at least one resilient arm attached to a second sensing tube of the sensor. The two sensing tubes, which are caused to vibrate during operation of the sensor, form a double-tube arrangement having a longitudinal gravity line, which lies in an imaginary central plane extending between the two, preferably parallel, sensing, tubes. The two arms of the mount are essentially rigidly connected to one another at a connecting location remote from the two sensing tubes, and the mount exhibits a first eigenmode of predeterminable mechanical resonance frequency, f1, at which the first arm attached to the first sensing tube and the second arm attached to the second sensing tube oscillate pendularly essentially perpendicular to the central plane of the double-tube arrangement. The mount exhibits a second eigenmode of predeterminable mechanical resonance frequency, f2, at which the first arm attached to the first sensing tube and the second arm attached to the second sensing tube oscillate pendu…
