Nuclear magnetic resonance flowmeter employing ceramic tube
Abstract
Abstract A NUCLEAR MAGNETIC RESONANCE FLOWMETER, EMPLOYING A CERAMIC TUBE AS A CONDUIT FOR PARAMAGNETIC FLUID, IS CONSTRUCTED USING MOLDABLE CERMAIC MATERIAL FOR ENCAPSULATING THE COIL STRUCTURE OF THE FLOWMETER. THE STRESSES ENCOUNTERED WITH HIGH PRESSURE, HIGH TEMPERATURE FLUIDS CAN BE ACCOMMODATED AND GRAPHITE SEALS PREVENT LEAKAGE OF THE FLUID FROM WITHIN THE CERAMIC TUBE. AT EACH END OF THE TUBE A COUPLING IS PROVIDED FOR CONNECTION TO A CONVENTIONAL CONDUIT. THE COIL STRUCTURE IS PROVIDED WITH APPARATUS FOR ASSISTING IN DECOUPLING THE RECEIVER COIL FROM THE OTHER COILS LOCATED IN PROXIMITY THERETO, TO REDUCE THE NOISE CONTENT OF THE OUTPUT SIGNAL FURNISHED BY THE RECEIVER COIL.
