3. Wide range of the electromagnetic flowmeter range, up to 1: 100. In addition, the average velocity of electromagnetic flowmeters only proportional to the measured medium, with the axis of symmetry of the flow regime (laminar or turbulent) irrelevant. 4. Electromagnetic flowmeter no mechanical inertia, responsive, and can measure the instantaneous flow pulsating electromagnetic flowmeters preferred high-quality, and good linearity, so you can measure the signal directly into a standard signal output converter linear conversion. LD-T type may indicate high-quality electromagnetic flowmeters offer, LD type can be long-distance transmission. The main technical data of the power supply interference. Electromagnetic flowmeters are generally used frequency AC power supply high-quality electromagnetic flowmeters wholesale changes in their supply voltage amplitude and frequency of the electromagnetic flowmeters will bring power to interference noise. Changes in the amplitude of the supply voltage, because the use of multi-level integrated voltage regulator, the magnitude of change in general supply voltage electromagnetic flow measurement accuracy is not affected. When the frequency of the power supply voltage fluctuations, although its fluctuation range is limited, but the electromagnetic flowmeter measurement accuracy greater impact. Intelligent use of square wave excitation pulse electromagnetic flow meter wide sampling technology, the pulse width is an integer multiple frequency cycle, with synchronized in frequency cycle of high-quality electromagnetic flowmeters to completely eliminate frequency interference, but with the proviso that work frequency noise basically unchanged. When the power supply frequency fluctuations, traffic signal samples before and after the time-frequency noise can not make the same, although the use of synchronous excitation technique, synchronous sampling techniques are still not completely eliminate frequency interference noise, frequency compensation must use the appropriate technology, the excitation current sampling pulse, a / d converter simultaneous changes in frequency.
