INTEGRAL TYPE ELECTROMAGNETIC FLOWMETER DATA SHEET The electromagnetic flowmeter is an instrument to measure the volumetric flow rate of liquid simply by applying a magnetic field from the outside utilizing the fact that an electric conductor which crosses a magnetic field at a certain velocity causes voltage to be induced in proportion to the velocity, which is known as Faraday’s law. This flowmeter is designed with the latest electronics technology and magnetic/electric field analyzing technology, realizing a compact and light-weight structure and measurement with high accuracy. FMA1, 2 FEATURES 1. High accuracy The adoption of the optimum magnetic field design using the 3-dimentional finite element method has minimized the effects of flow velocity profile and materials of adjacent piping. At flow velocity of more than 1m/sFS,the measurement accuracy is as high as ± 0.5% of indicatedvalue when the flow is above 20%FS. 2. Wide range Measurement range: 0 to 0.1 ... 15m/sec in flow velocity 3. High-reliability structure The converter case is a sealed 2-chamber structure, practically free from dew condensation and sudden submergence. The adoption of stainless housing assures excellent anti-environment efficiency. 4. Easy-to-see display LCD with back-light allows easy check of display even in a dark place. Instantaneous flow and integral volmetric flow are displayed at the same time. 5. Free power supply The flowmeter operates on power supply 100 to 240V AC, 50/60 Hz, eliminating the need for selection of power voltage. 6. Application of international standards The overall length of flange type flowmeter conforms with ISO draft standards.
