YHLD型智能電磁流量計是一種測量導電介質體積流量的感應式儀表，在進行現(xiàn)場監(jiān)測顯示的同時，可輸出標準的電信號，供記錄﹑調節(jié)﹑控制使用。可廣泛應用于自來水、化工、煤炭、環(huán)保、輕紡、冶金、造紙等行業(yè)。 YHLD Intelligent Electromagnetic Flowmeter is a kind of inductive meter, measuring volume flow of conducting medium. When conducting on-site monitoring display, it can output a standard signal, which is used for record, adjustment and control. It can be widely used in tap water, chemicals, coal, environmental protection, textile, metallurgy, paper making and other industries.主要特點 Main features: ● 測量管內無可動部件，便于維護管理；無阻流部件，因此無壓力損失No moving parts inside measuring pipe, easy maintenance and management. Unimpeded flow of parts, less pressure loss. ● 流量的測量不受流體的密度、粘度、溫度、壓力和電導率變化的影響，傳感器感應電壓信號與平均流速呈線性關系，測量精度高Fluid density, viscosity, temperature, pressure and electrical conductivity change does not affect the flow measurement, a linear relationship between mean velocity and the sensor of voltage signal, high accuracy. ● 合理選用襯里及電極材料，可實現(xiàn)良好的耐腐蝕性和耐磨性 A reasonable selection of lining and electrode materials, achieving good corrosion resistance and wear resistance. ● 低頻矩形波激磁，不受工頻及現(xiàn)場各種雜散干擾的影響，工作穩(wěn)定可靠Low-frequency square wave excitation, good ant-jamming, reliable and stable● 量程寬，可測下限流速低 Wide-range meter, Lower limit of the measured low velocity主要技術參數 Main technical parameters:● 儀表口徑 Meter diameter: DN10~DN1600● 公稱壓力: PN1.0 ~ PN4.0（特殊要求協(xié)議供貨）Nominal pressure rating: PN1.0~PN4.0 (special requirement need supply by agreement)● 法蘭連接 Flange coupling: Chinese standard GB/9119-2000 [carbon steel, stainless steel] [OEM Manufacturer]Following required flange standard by customer supply with agreement.[Metric unit/inch unit]Our company supply the Inch Unit with USA, German Japanese Standard etc. ● 介質溫度 Medium temperature: -20 C~120 C● 防護等級 Protection level: IP65、IP67、 IP68● 電 極: 1.標準型為不銹鋼1Cr18Ni9Ti （0Cr18Ni12Mo2Ti） 2.特殊型為哈氏合金B(yǎng)或C﹑鈦﹑鉭﹑鉑銥合金Electrode: 1.
