是应用户需要在地下容器上开孔位置要求而开发的新一代液位计， 跟UIZ内装型液位相比，具有价格便宜、能适用于易燃易爆、有毒、强腐蚀性和挥发性的环境中工作，是UFZ侧装型磁性翻板液位计的特殊型、具有安全可靠、观察方便、液位指示清晰等特点，广泛应用于油库、 地下储罐、槽等容器及食品、化工、化肥等行业上，同时在该液位计上配上有关的配件，还具有报警和控制信号输出功能。 UFDZ top-mounted (bottom-mounted) magnetic flap level gauge is a new-generation level gauge developed in response to the user's need to open the hole in the underground container. Compared with UIZ built-in level, it has a lower price and can be applied. It works in flammable and explosive, toxic, highly corrosive and volatile environments. It is a special type of UFZ side-mounted magnetic flap liquid level gauge, which is safe, reliable, convenient to observe, and clear in liquid level indicators. It is widely used. It is used in oil depots, underground storage tanks, tanks and other containers, as well as in food, chemical, fertilizer and other industries. At the same time, the level gauge is equipped with related accessories, and it also has alarm and control signal output functions. zzyfwh.com
主要技术指标 Main technical indicators of top-mounted (bottom-mounted) magnetic flap liquid level gauge
1. Measuring range (mm): 300 ～ 6000
2. Medium density (g / cm3): 0.5 ～ 2
3. Working temperature (℃): -40 ～ 350
4.Pressure level (MPa): ≤32
5.Measurement accuracy (mm): ≤ ± 10
由本体(由上、下导管组成)，翻板箱(由红、白双色磁性小翻板组成)，浮子(由磁体、顶杆、浮筒组成)等组成，其结构如图所示，工作原理为:容器内的浮筒(按不同介质和压力针对研制)，在下导管中随液面高度的变化而上下浮动并通过顶杆使磁体在上导管内上下移动，促使本外的翻板翻动并用红，白颜色来指示液位高度。 Top-mounted (bottom-mounted) magnetic flap liquid level gauge consists of the body (consisting of upper and lower conduits), flap box (consisting of small red and white magnetic flaps), and float (consisting of magnet, ejector, and float) ) And other components, the structure is shown in the figure, the working principle is: the buoy in the container (developed according to different media and pressure), in the lower tube with the liquid level height changes up and down, and the magnet through the ejector rod in the upper tube Moving up and down inside and outside causes the flips inside and outside to flip and use red and white colors to indicate the level of the liquid level.
1. When the container is not suitable for side openings and there is little space around the container, a liquid level gauge of this form can be installed above or below the container
2.Suitable for liquid media with large viscosity
3.The viewing direction of the display can be changed arbitrarily
4. Other characteristics are the same as those of UFZ
1. Nominal pressure of anti-corrosion type ≤ 1.0MPa.
2. The liquid level gauge has a certain dead zone, so the blind zone value compensation should be added when reading the liquid level height.
3. The measuring range of the level gauge does not exceed 5 meters, otherwise it will affect the stability, reliability and fastness of the level gauge.
4. Install the connection flange. The dimensions of the commonly used protruding surface of this level gauge are manufactured according to (HG21592-97).
Installation and maintenance
1.The liquid level protection tube and the main tube must be kept vertical
2. The connecting rod cannot be bent and must be inserted upright
3. After the installation is completed, guide the column of the display with magnetic steel once to display white above zero and red below zero.
