ABSTRACT:
The invention is a non-intrusive system for measuring the flow rates of insulating or conducting fluids in conduits. It results from the combination of an electromagnetic flowmeter, operating with conducting fluids, and of a triboelectric noise cross-correlation flowmeter, operating with insulating fluids. The system is equipped with a non-intrusive device for measuring fluid conductivity. The electronic signal processing unit uses the conductivity value to decide which of the two sensors is providing a signal effectively representing the fluid flow rate. The electromagnetic flowmeter may use electrodes of small cross-section in contact with the fluid or, more advantageously, it may be of the capacitive type using larger section electrodes isolated from the fluid.
