Electromagnetic flowmeters are widely used in the measurement of liquid media in industrial production. An electromagnetic flowmeter operates on the principle of electromagnetic induction; therefore, as long as the liquid has a certain level of electrical conductivity, it can be used as a tool for measuring the flow rate of such fluids. It is most widely used in industrial production sites involving conductive liquids such as water, sewage, sulfuric acid, and ammonia. What are the power supply options for electromagnetic flowmeters? Currently, the main options include 220V, 24V, and battery power. Different power supply methods correspond to various operational requirements, and the differences between them will be explained below. 1. Electromagnetic flowmeters powered by 220V are currently the most widely used; most industrial sites have a 220V power supply. Once installed as required and connected to power, such flowmeters can operate. 220V-powered electromagnetic flowmeters can be designed as integrated or modular types. If the flow meter is located far away from the control room, it is advisable to use a 220VAC electromagnetic type, as long cables can cause signal attenuation; therefore, an external 220VAC power supply is needed to stabilize the voltage. II. 24V-powered electromagnetic flowmeters are mainly used in industrial environments where the use of alternating current is not permitted, or where low-voltage direct current is preferred for safety reasons, or in conjunction with volume measurement instruments ； The electromagnetic flowmeter is powered by an integrator, and only 24V can be selected. When the flow meter is not far from the control room, a 24VDC electromagnetic type can be chosen; this indeed helps to save on power supply requirements, and no partitions are needed when laying the cables in cable trays ； III. Battery-powered electromagnetic flowmeters are not widely used at present; they are mainly employed in situations where there is no power supply available on site. It also features a fault alarm function, settings and alarm functions for upstream and downstream flow rates, as well as a function to switch between forward and reverse flow directions. But its price is much higher than that of similar products. For more information, please visit the company’s official website at http://www.yb1518.com/.
