Method for adjusting the volumetric flow ratio of at least two different fluids (F1, F2) with a control-device. The control-device comprises a first chamber with a chamber-volume (V.sub.C1) for the first fluid (F1) and an inlet-element and an outlet-element for the first fluid (F1) and at least one rotating or nutating element. The control-device further comprises at least one second chamber with a chamber-volume (V.sub.C2) for the second fluid (F2), wherein the second chamber has an inlet-element and an outlet-element for the second fluid (F2) and at least one rotating or nutating element.

The chamber volume ratio (V.sub.C1:V.sub.C2) and the rotational or nutational frequency ratio are selected such that the fluids (F1, F2) flowing out of the outlet-elements have a predefined volumetric flow ratio. The input resistor (R.sub.i) of the respective inlet-element and the output resistor (R.sub.o) of the respective outlet-element of the first chamber and/or the second chamber are chosen so as to satisfy the equation: (I), wherein ?.sub.F is the viscosity of the respective fluid (F1, F2) and Cn designates the respective chamber.

A device and principal method for measuring flow through a pipe for liquid and compressed gas. In an embodiment, the device is comprised of eccentric disk, rotation sensor, torque/stress sensor, coil spring, track rod, supports, and a digital processor. The processor determines the flow based on measured torque/stress, rotation, and other pre-determined parameters and relationship equations. The processor also provides data communication with other controllers and human-machine interface devices. In one simplified option, the arm may be fixed in one position and the rotation sensor is eliminated. In another simplified option, the torque sensor is removed. The compression of coil spring is measured by the rotation sensor. The torque is then determined using the coil spring performance and measured coil spring compression. The torque based flowmeter can be implemented to any industrial corrosive liquids, water, and gas with or without suspended solids.

A sensor may include a substrate defining a flow channel that extends through the substrate, and a plurality of bond pads on the substrate. A first housing may be disposed along the substrate and may permit at least some fluid to flow from a fluid inlet to a fluid outlet along at least part of the flow channel. A second housing may be disposed along the substrate. A sense die may be disposed between the second housing and the substrate and may include a sensing side facing the substrate with a sense element in registration with the flow channel and a plurality of bond pads on the sensing side that are in registration with, and bump bonded to, the plurality of bond pads on the substrate. An adhesive or other material may be disposed between the sensing side of the sense die and the substrate.
