Abstract: A flowmeter comprising a disc-like target member mounted in a flow conduit and which forms an obstruction to flow. The meter includes means to measure the differential in pressure on opposite faces of the target or obstruction body to determine the flow rate as a function of such differential in pressure.

Abstract: A capacitive type load cell utilizing a support, a diaphragm member mounted with respect to said support for movement relative thereto, said diaphragm having a conductive surface, and a capacitor plate attached to the diaphragm so that upon deflection of the diaphragm there will be relative movement between the diaphragm and the capacitor plate. The diaphragm is constructed to provide free edge bending characteristics both at its outer peripheral edges, and between the diaphragm and the load support button, to thereby reduce radial bending stresses in the diaphragm during loading.

Abstract: Sensors including radiation detectors and the like for use within the core of nuclear reactors and which are constructed in a manner to provide optimum reliability of the sensor during use.
