Abstract: A sensing valve comprises: (a) a valve body defining a chamber; (b) a control member configured for controlling a fluid flow through the chamber; (c) inlet and outlet ports; and (d) a sensor arrangement for measuring at least one characteristic of the fluid flow and (e) a microprocessor configured for acquiring and processing data from said sensor arrangements. The microprocessor is preprogrammed for calculating and reporting predetermined characteristics of said incoming and outcoming flows. The sensor arrangement comprises an inlet sensor being in fluid connection with the fluid flow incoming into the inlet port and an inlet sensor arrangement being in fluid connection with the fluid flow incoming into the inlet port.
