<p>This invention relates generally to electromagnetic flow meters, and more particularly to a flangeless flowmeter whose components are integrated to form a highly compact, lowcost unit that may be readily installed in. a flow line, the unit being compressible between the flanged ends of the upstream and downstream pipes and being capable of withstanding high compressive forces. Magnetic flowmeters such as those disclosed in U.S. Patents 3,695,104; 3,824,856; 3,783,687 and 3,965,738, are especially adapted to measure the volumetric flow rates of fluids which present difficult handling problems, such as corrosive acids, sewage and slurries. Because the instrument is free of flow obstructions, it does not tend to plug or foul. The flowmeter can be used to meter liquids without regard to heterogeneous consistency. An added advantage of an obstructionless construction is that pressure losses are reduced to levels encountered in equivalent lengths of equal diameter pipeline, thereby reducing or conserving pressure source requirements in new or existing hydraulic lines as compared to other metering techniques.</p> |
