ABSTRACT:
A precision pressure gauge in which a sleeve is installed between the open section of a cylinder and the ram so as not to rotate the ram but only to rotate the sleeve, and the ram is actuated by fluids led into a cylinder chamber of the cylinder so that the force exerted on the ram is transmitted to a precision electronic weight measuring instrument for continuous high precision measurement of the aforementioned fluids.
