The electromagnetic flowmeter consists of two main parts: a flow sensor and a transmitter. The sensor measurement pipe is equipped with excitation coils above and below. After passing the excitation current, a magnetic field is generated and passes through the measurement tube. A pair of electrodes are installed on the inner wall of the measurement tube and come into contact with the liquid, leading out the induced electromotive force and sending it to the transmitter.
\nAssuming that the magnetic field intensity (B) generated by the electromagnetic induction coil is constant, the induced voltage (Ue) generated is proportional to the fluid velocity (v), the constant (C), and the cross-sectional area of the pipeline and pipeline (A) are known, the volumetric flow rate (Q) can be calculated using the following formula:
\nUe=C*B*L*v
\nQ=v*A
\nThe flow rate is linearly related to the fluid velocity, with a simple principle and accurate measurement.<\/p>\n","protected":false},"featured_media":3550,"parent":0,"menu_order":0,"template":"","tags":[],"product":[506],"size":[],"material":[],"class_list":["post-3553","products","type-products","status-publish","has-post-thumbnail","hentry","product-flow-meter","post1-3553"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/products\/3553","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/products"}],"about":[{"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/types\/products"}],"version-history":[{"count":1,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/products\/3553\/revisions"}],"predecessor-version":[{"id":3555,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/products\/3553\/revisions\/3555"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/media\/3550"}],"wp:attachment":[{"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/media?parent=3553"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/tags?post=3553"},{"taxonomy":"product","embeddable":true,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/product?post=3553"},{"taxonomy":"size","embeddable":true,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/size?post=3553"},{"taxonomy":"material","embeddable":true,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/material?post=3553"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
