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 mount exhibits a first eigenmode of predeterminable mechanical resonance frequency, at which the first arm and the second arm oscillate pendularly essentially perpendicular to the central plane of the double-tube arrangement. The mount exhibits a second eigenmode of predeterminable mechanical resonance frequency, at which the first arm and the second arm oscillate pendularly essentially parallel to the central plane of the double-tube arrangement, and the resonance frequency, of the first eigenmode is different from the resonance frequency, of the second eigenmode.
