電磁流量計(jì)的結(jié)構(gòu)主要由磁路系統(tǒng)、測量導(dǎo)管、電極、外殼、襯里和轉(zhuǎn)換器等部分組成。
The structure of electromagnetic flowmeter is mainly composed of magnetic circuit system,measuring duct,electrode,shell,lining and converter.
特點(diǎn):
Characteristic:
1、測量不受流體密度、粘度、溫度、壓力和電導(dǎo)率變化的影響;
2、測量管內(nèi)無阻礙流動(dòng)部件,無壓損,直管段要求較低。對(duì)漿液測量有獨(dú)特的適應(yīng)性;
3、合理選擇傳感器襯里和電極材料,即具有良好的耐腐蝕和耐磨損性;
4、轉(zhuǎn)換器采用新穎勵(lì)磁方式,功耗低、零點(diǎn)穩(wěn)定、精確度高。流量范圍度可達(dá)150:1;
5、轉(zhuǎn)換器可與傳感器組成一體型或分離型;
6、轉(zhuǎn)換器采用16位高性能微處理器,2x16LCD顯示,參數(shù)設(shè)定方便,編程可靠;
7、流量計(jì)為雙向測量系統(tǒng),內(nèi)裝三個(gè)積算器:正向總量、反向總量及差值總量;可顯示正、反流量,并具有多種輸出:電流、脈沖、數(shù)字通訊、HART;
8、轉(zhuǎn)換器采用表面安裝技術(shù)(SMT),具有自檢和自診斷功能;
9、測量精度不受流體密度、粘度、溫度、壓力和電導(dǎo)率變化的影響,傳感器感應(yīng)電壓信號(hào)與平均流速呈線性關(guān)系,因此測量精度高。
10、測量管道內(nèi)無阻流件,因此沒有附加的壓力損失;測量管道內(nèi)無可動(dòng)部件,因此傳感器壽命極長。
11、由于感應(yīng)電壓信號(hào)是在整個(gè)充滿磁場的空間中形成的,是管道載面上的平均值,因此傳感器所需的直管段較短,長度為5倍的管道直徑。
12、轉(zhuǎn)換器采用國際最新最先進(jìn)的單片機(jī)(MCU)和表面貼裝技術(shù)(SMT),性能可靠,精度高,功耗低,零點(diǎn)穩(wěn)定,參數(shù)設(shè)定方便。點(diǎn)擊中文顯示LCD,顯示累積流量,瞬時(shí)流量、流速、流量百分比等。
13、雙向測量系統(tǒng),可測正向流量、反向流量。采用特殊的生產(chǎn)工藝和優(yōu)質(zhì)材料,確保產(chǎn)品的性能在長時(shí)候內(nèi)保持穩(wěn)定。
1.The measurement is not affected by the changes of fluid density,viscosity,temperature,pressure and conductivity.
2.There are no obstructive flow components,no pressure loss in the measuring tube,and the requirement of straight pipe section is low.It has unique adaptability to slurry measurement.
3.Reasonable selection of sensor lining and electrode materials,that is,good corrosion resistance and wear resistance;
4.The converter adopts a novel excitation mode with low power consumption,zero stability and high accuracy.The flow range can reach 150:1.
5.The converter can be integrated or separated from the sensor.
6.The converter uses 16-bit high-performance microprocessor,2x16LCD display,convenient parameter setting and reliable programming.
7.Flowmeter is a bidirectional measurement system with three integrators:total forward,total reverse and total difference.It can display both positive and negative flow,and has a variety of outputs:current,pulse,digital communication and HART.
8.The converter adopts surface mounting technology(SMT),which has self-inspection and self-diagnosis functions.
9.The measurement accuracy is not affected by the changes of fluid density,viscosity,temperature,pressure and conductivity.The induction voltage signal of the sensor has a linear relationship with the average velocity of flow,so the measurement accuracy is high.
10.There is no obstruction in the measurement pipeline,so there is no additional pressure loss;there is no movable parts in the measurement pipeline,so the sensor has a very long life.
11.Because the induction voltage signal is formed in the whole space filled with magnetic field and is the average value on the pipeline surface,the straight pipe section needed by the sensor is shorter,and the length is five times the diameter of the pipeline.
12.The converter adopts the latest and most advanced MCU and SMT technology in the world.It has reliable performance,high precision,low power consumption,stable zero point and convenient parameter setting.Click on Chinese to display LCD,showing cumulative flow,instantaneous flow,flow rate,flow percentage,etc.
13.Two-way measurement system can measure forward and reverse flow.Special production technology and high-quality materials are adopted to ensure that the product performance remains stable in the long run.
