How to better buy a magnetic flap level meter?
又称磁性液位计,磁翻柱液位计,磁浮子液位计,它是利用磁藕合原理进行工作的,产品弥补了玻璃管液位计不能在高温高压下工作且易碎的多重缺点. 磁翻板液位计有侧装和顶装二种安装方式,无论那种方式都可以捆绑远传装置,使液位计即可以就地显示液位,又可以远程监控液位.捆绑后的磁翻板液位计可称为远传型磁翻板液位计. 制作磁翻板液位计的工艺虽然很简单,但磁翻板液位计作为计量仪表,特别是远传型磁翻板液位计，如果未经质监局审核,没有生产许可证,产品质量是难以得到保证的.因此,采购磁翻板液位计要选择有生产许可证且信誉好的厂家,价格可能略高一点,但产品质量有保证,售后服务有保证。 Magnetic plate level gauge is also called magnetic level gauge, magnetic column level gauge, magnetic float level gauge.It uses the principle of magnetic coupling to work.The product makes up for the glass tube level gauge cannot be under high temperature and high pressure. Multiple shortcomings of working and fragile. The magnetic flap liquid level gauge has two mounting methods, side mounting and top mounting. No matter which way, the remote transmission device can be bundled, so that the level gauge can display the liquid level on the spot and can Remote monitoring of liquid level. The bundled magnetic flap level gauge can be called a remote transmission magnetic flap level gauge. Although the process of making a magnetic flap level gauge is simple, the magnetic flap level gauge is used as a measuring instrument In particular, the remote transmission type magnetic flap level gauge is difficult to guarantee product quality if it has not been audited by the Quality Supervision Bureau and without a production license. Therefore, when purchasing a magnetic flap level gauge, it is necessary to choose a production license and Reputable manufacturers, the price may be slightly higher, but product quality is guaranteed, after-sales service is guaranteed. Jiangsu Jinhu Dongxiang Instrument Cable Co., Ltd. is the best choice for everyone.
指示器安装在桶槽外侧或上面，用以指示和控制桶槽内的封形式可根据需要加装排污阀。 The magnetic flap liquid level indicator is installed outside or above the bucket tank, which is used to indicate and control the seal form in the bucket tank. A drain valve can be added as required. The connection flange can be a control instrument for customizing the liquid level height. The indicator consists of magnetic color chips. When the magnetic floating ball in the body tube rises with the liquid level, the color film is flipped to display the liquid level height. It is also possible to install a magnetic switch or remote transmitter on the body tube to output a switch signal or an analog signal. It is suitable for high temperature, high pressure, corrosion resistance and other occasions. It can be displayed and controlled remotely. The body pipe is made of seamless steel pipe, and the connecting pipe is welded with pull holes, and there is no scratch inside. The installation method can be side or top, and the lower end of the body is sealed.
安装必须垂直，磁翻板液位计与容器引管间应装有球阀，便于检修和清洗;2. 磁翻板液位计本体周围不容许有导磁物质接近，禁用铁丝固定，否则会影响磁翻板液位计的正常工作3. 如用户自行采用伴热管路时，必须选用非导磁材料，如紫铜管等。 1. The magnetic flap liquid level gauge must be installed vertically. A ball valve should be installed between the magnetic flap liquid level gauge and the container's guide tube to facilitate maintenance and cleaning. 2. The magnetic flap liquid level gauge body is not allowed to have magnetically conductive substances around it. It is forbidden to fix the iron wire, otherwise it will affect the normal operation of the magnetic flap liquid level gauge. 3. If the user adopts the heat tracing pipeline, he must choose non-magnetic conductive materials, such as copper pipes. The heat tracing temperature is determined according to the condition of the medium; 4. There should be no solid impurities or magnetic substances in the medium to avoid blocking the float; 5. Before use, the small ball below zero should be set to red with calibration magnetic steel, other The ball is set to white; 6. Open the bottom flange and install the magnetic float (Note: the magnetic end with the heavy end is up and cannot be inverted.); 7. When debugging, first open the upper lead valve and then slowly open the lower valve. Allow the medium to enter the main pipe smoothly (you should avoid the medium from rapidly impacting the float during operation, which will cause the float to fluctuate and affect the accuracy of the display). Observe whether the magnetic red and white ball is flipped normally, and then close the lower introduction valve and open the drain valve. The liquid level drops, and it is normal to operate three times according to this method, and it can be put into operation (except for special liquids such as corrosives); 8. The main pipe should be cleaned irregularly to remove impurities according to the condition of the medium; Type> 3 meters, anti-corrosion type> 2 meters) level gauge, need to increase the intermediate reinforcement flange or ear climbing as a fixed support to increase strength and overcome its own weight;
10. The installation position of the magnetic flap liquid level meter should avoid or stay away from the inlet and outlet of the material medium to avoid rapid changes in the local area of the material fluid and affect the accuracy of the liquid level measurement; 11. When equipped with remote transmission supporting instruments Need to do the following:
(A) The remote transmission supporting instrument should be close to the main pipe of the level gauge and fixed with stainless steel hoop (iron is prohibited); (b) The remote transmission supporting instrument's zero position should be on the same level line as the zero indicator of the liquid level gauge (C) The sensing surface on the remote supporting instrument should be facing and close to the main duct;
(D) The connection between the remote transmission supporting instrument and the display instrument or industrial control computer should be laid through a protective tube alone or with a shielded two-core cable; (e) After the wiring hole of the junction box is laid, it must be sealed well to prevent rain , Moisture and other intrusions make remote transmission supporting instruments unable to work properly, the junction box should be covered in time after maintenance or commissioning is completed.
