A Mass Flow Measurement Device
A capacitive pick off sensor (1) for a mass flow measurement device is disclosed. Said device comprises a flow sensor tube (2) and a drive device (3) for vibrating the flow sensor tube (2). Said capacitive pick off sensor comprises at least one conductive plate connectable to a first voltage potential and adapted to be situated adjacent the flow sensor tube (2) which is connected to a second voltage potential. The conductive plate is positioned relative to the flow sensor tube (2) so as to define a gap therebetween. The capacitance between the conductive plate and the flow sensor tube (2) varies due to relative motion of the conductive plate and the flow sensor tube (2) when the flow sensor tube (2) is vibrated. In other aspects of the present invention, the flow sensor tube (2) is situated in a housing and the drive device is positioned outside the housing for vibrating the flow sensor tube (2).

A MASS FLOW MEASUREMENT DEVICE
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
The invention relates generally to a mass flow measurement and control, and more
particularly, to a mass flow measurement and control device based on the Coriolis force effect
and having an integrated flow control valve with associated sense, control and communication
electronics.
2. DESCRIPTION OF RELATED ART
Mass flow measurement based on the Coriolis force effect is achieved in the following
manner. The Coriolis force results in the effect of a mass moving in an established direction and
then being forced to change direction witfi a vector component normal to the established
direction of flow. This can be expressed by the following equation:
Fc = Mxvs
Where Fc (the Coriolis force vector) is the result of the cross product of M (the mass flow
vector) and
