<p>Measurement unit, particularly for hydraulic ducts, that comprises at least one main duct (2) that is provided with at least one intake section (2a) and at least one discharge section (2b) for a fluid. The unit comprises: at least one main flowmeter (3), for measuring the value of the flow-rate along the main duct (2) within a first measurement range; at least one auxiliary flowmeter (4), for measuring the value of the flow-rate along an auxiliary duct (5) within a second measurement range; at least one flow control element (6), that is arranged along the main duct (2), and that is selectively operated to divert the flow from the main duct (2) to the auxiliary duct (5), which is arranged in parallel to the flow control element (6); at least one control and management unit that is operatively associated with the main flowmeter (3) and the auxiliary flowmeter (4) in order to acquire and elaborate, at a desired rate, the signal that corresponds to the detections of the main flowmeter (3) and the auxiliary flowmeter.(4).</p> |
