Pinch valve monitoring

Abstract

A method for monitoring a pinch valve, the method may include sensing an electrical parameter of at least one flexible sensor during a monitoring period to provide multiple values of the sensed electrical parameter; wherein the at least one flexible sensor comprises piezoresistive nanomaterials, wherein the piezoresistive nanomaterials are directly coupled to a flexible conduit of the pinch valve; wherein the sensed electrical parameter is indicative of a flexible conduit parameter selected out of stress and pressure; and estimating, based on the multiple values of the sensed electrical parameter, a state of the pinch valve.
