APPARATUS FOR MEASURING PRESSURE LOSS OR FLOW RATE OF HIGH VISCOSITY SLURRY FLUID AND MANUFACTURE OF ITS MEASURING TUBE

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for measuring pressure loss or flow rate of high viscosity slurry fluid easy for handling and maintenance with a simple constitution. SOLUTION: The apparatus for measuring pressure loss or flow rate of high viscosity slurry fluid comprises a measuring tube 20 having a lining 21 of a soft rubber on its inner surface and no constrictions and a remote seal diaphragm type differential pressure oscillator 10. In this case, the tube 20 has pressure receiving ports 22, 23 isolated at a predetermined distance L. Sensors 12, 13 of the oscillator 10 are brought at their pressure measuring diaphragms 14, 15 into close contact with a rear surface of the lining 21 of the tube 20 and mounted at the ports 22, 23. With such a constitution, differential pressure or hence pressure loss of the high viscosity slurry fluid is measured from the rear surface of the lining 21 of the tube 20.
