Degao’s high-precision and long-life plug-in electromagnetic flowmeter is a new type of fluid flow instrument developed on the basis of pipeline electromagnetic flowmeter. On the basis of retaining the advantages of pipeline electromagnetic flow meters, it addresses the difficulties and high costs of installing pipeline electromagnetic flow meters on large pipelines. According to the principle of NIKURADS, electromagnetic methods are used to measure the average flow velocity of the fluid, thereby obtaining the volume flow rate of the fluid. Especially with the use of pressurized opening and installation technology, the plug-in electromagnetic flowmeter can be installed without stopping (water), as well as on cast iron pipelines and cement pipelines. The successful development of the Degao plug-in electromagnetic flowmeter, compared with similar domestic products, combines international advanced flow compensation algorithms and fluid models, coupled with Degao's unique low-power core converter, providing a new means and choice for high-end user detection of fluid flow. Its stability, accuracy, failure rate, and anti-interference ability are comparable to international first tier brands.
Degao’s high-precision and long-life plug-in electromagnetic flowmeter is a fully intelligent fifth generation electromagnetic flowmeter developed by the Degao R&D team after five years of continuous technological upgrades. It consists of two parts: an plug-in sensor and a converter, and can be divided into three products according to different power supply methods.
① 3.6VDC built-in lithium battery power supply, IP68 protection level, integrated installation of flow, pressure, and remote transmission.
② 220VAC/24VDC power supply: split type sensor IP68, converter IP65, multi parameter measurement: flow rate, pressure, remote transmission.
③ 3.6VDC+solar power supply: multi parameter measurement: flow rate, pressure, remote transmission.
The plug-in flow meter powered by large capacity industrial lithium batteries is
