<p>The borehole instrument contains a pair of bellows which are equally spaced from a differential pressure transducer to provide equal temperature expansion of the liquid to provide a true reading on the transducer. A third bellows is connected between the borehole fluid and the exterior of the transducer housing to eliminate pressure buildup in or around the transducer. The instrument has utility in finding oil-water, gas-oil and gas-water interfaces and other combinations of fluid interfaces by measuring the differential pressure across the interface.</p> |
