Reasons include power failure, connection cable failure, sensor or converter element damage, excessive minimum cut-off flow, process reasons include changes in liquid flow conditions, and problems with the adhesion layer of the process pipeline.<br \/>\n<strong>2.<\/strong>\u00a0 The electromagnetic flowmeter shows maximum reading: In addition to the actual operating conditions exceeding the range, the reasons for the instrument itself include: signal circuit open circuit, connection cable failure, wiring error, etc., sensor and converter matching errors, electromagnetic flowmeter setting error.<br \/>\n<strong>3.<\/strong>\u00a0 The electromagnetic flowmeter display is too high or low: the zero point of the meter is not adjusted or set; the sensor installation position does not meet the requirements; the straight pipes before and after the sensor cannot meet the requirements; the tube cannot be fully filled with liquid or the liquid contains air bubbles; The insulation of the sensor electrode drops.<br \/>\n<strong>4.<\/strong>\u00a0 Electromagnetic flowmeter shows fluctuations: the main interferences are stray current, static electricity, electromagnetic waves, and magnetic fields on the pipeline. The reasons for the electromagnetic flowmeter itself are: oxidation of the wiring terminal; poor contact of the circuit board; contamination of the measuring electrode; improper installation of the gasket; pipe not fully filled with liquid; the liquid containing air bubbles; and the grounding unreliable.<\/p>","protected":false},"excerpt":{"rendered":"<p>Common faults and troubleshooting of electromagnetic flow meter<\/p>","protected":false},"author":1,"featured_media":2768,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[2130],"tags":[],"acf":[],"_links":{"self":[{"href":"https:\/\/www.hginstrument.com\/fr\/wp-json\/wp\/v2\/posts\/3002"}],"collection":[{"href":"https:\/\/www.hginstrument.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hginstrument.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hginstrument.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hginstrument.com\/fr\/wp-json\/wp\/v2\/comments?post=3002"}],"version-history":[{"count":0,"href":"https:\/\/www.hginstrument.com\/fr\/wp-json\/wp\/v2\/posts\/3002\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.hginstrument.com\/fr\/wp-json\/wp\/v2\/media\/2768"}],"wp:attachment":[{"href":"https:\/\/www.hginstrument.com\/fr\/wp-json\/wp\/v2\/media?parent=3002"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hginstrument.com\/fr\/wp-json\/wp\/v2\/categories?post=3002"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hginstrument.com\/fr\/wp-json\/wp\/v2\/tags?post=3002"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
