帶遠傳磁翻板液位計Remote transmission magnetic flap level gauge
磁翻板液位計是現(xiàn)場液位顯示儀表。它是一種多功能儀表，是玻璃板（管）液位計的更新?lián)Q代產品。液位顯示部位寬、醒目、無顯示盲區(qū)、可遠距離觀測，使用過程中不會出現(xiàn)泄露現(xiàn)象。它既能實現(xiàn)現(xiàn)場液位顯示，又能實現(xiàn)4-20mA遠傳，并配有液位報警開關。適用于一﹑二﹑三類壓力容器及工藝過程控制的液位顯示，并可用于易燃、易爆和有毒環(huán)境中。
結構原理：
BDCFZ現(xiàn)場顯示型磁翻板液位計主要有磁浮子、立管和指示器構成，磁性浮子在立管內與液位同步浮動，浮子中的磁鋼通過磁耦合作用驅動指示器上的磁翻板同步轉動變換顏色，紅色顯示液相，白色顯示氣相，紅白界面就是容器內的實際液位。
報警開關是磁浮子液位計專用的自保持型于簧管開關，將其安裝在
磁浮子液位計的立管上相應的報警位置。浮子隨液體上升和下降，感應相應的報警開關實現(xiàn)報警控制。
遠傳變送器是安裝在磁翻板液位計的立管上，由于浮子隨液位上下浮動使干簧管繼電器對信號電阻進行切換，隨變送器電路輸出與液位相應的DC 4～20mA標準信號。

The magnetic flap level gauge is a field-level display instrument. It is a multi-functional instrument and is an updated version of the glass plate (tube) level gauge. The liquid level display area is wide, conspicuous, has no display blind zone, and can be observed remotely. During use, there will be no leakage phenomenon. It can not only achieve on-site liquid level display, but also realize 4-20mA remote transmission, and is equipped with a liquid level alarm switch. It is suitable for the liquid level display of Class I, II, and III pressure vessels and process control, and can also be used in flammable, explosive, and toxic environments.
Structural principle:
The BDCFZ on-site display type magnetic flap level gauge is mainly composed of a magnetic float, a vertical pipe, and an indicator. The magnetic float floats synchronously with the liquid level in the vertical pipe. The magnetic steel in the float drives the magnetic flap on the indicator to rotate synchronously and change colors. The red color indicates the liquid phase, the white color indicates the gas phase, and the red-white interface is the actual liquid level in the container.
The alarm switch is a self-retaining type spring tube switch specifically for magnetic float level gauges. It is installed on the corresponding alarm position of the magnetic float level gauge's vertical pipe. As the float rises and falls with the liquid, it senses the corresponding alarm switch to achieve alarm control.
The remote transmitter is installed on the vertical pipe of the magnetic flap level gauge. As the float floats up and down with the liquid level, the reed switch relay switches the signal resistance, and the output of the transmitter circuit corresponds to the DC 4-20mA standard signal of the liquid level.
