◆ 罐外安装,不开孔,不动火,不损伤罐体,可不停产安装,不停产维修; ◆ Outside the pot installs, the opening, does not get angry, does not damage the shell of tank, but does not suspend production the installment, does not suspend production the service; ◆非接触式测量:*理想的液位测量方式,与介质的压力、比重、有无腐蚀性无关,适应面广; ◆ Does the non-jack-in survey, with the medium pressure, the proportion, whether there is corrosiveness have nothing to do with, the adaptation suRFace is broad; ◆ 外贴测量,对罐内或装置内介质不产生干扰,无污染、无泄露、无腐蚀; ◆ Outside pastes the survey, the medium does not have the disturbance to the pot in or the installment, does not have the pollution, not to have the revelation, not to have the corrosion; ◆ 适用于石化常压或高压罐及装置、对卫生要求严格的食品罐、医药卫生罐及强腐蚀性罐,是一种环保型仪表; ◆ Is suitable for the petrochemical atmospheric pressure or the high-pressured pot and the equipment, to the hygienic request strict food pot, the medicine health pot and the strong corrosive pot, is one kind of environmental protection measuring appliance; ◆ 配有多种探头,既可测常温罐,又可测高温罐(*高温度200℃)。 ◆ Has many kinds of probe heads, both observable normal temperature pot, and observable high temperature pot (maximum temperature 200℃). 4.液化气液位计技术参数
5.应用条件 5.1适用介质 纯净度:液体中不能充满气泡、不能悬浮大量固体(如结晶物)、罐底部不能有大量沉淀物。 粘度:动力粘度<30mPa·S。 5.2常用被测容器 材质:密实性材料,如:碳钢、不锈钢、各种硬金属、玻璃钢、硬塑料、陶瓷或其他复合材料等。安装探头处的容器壁为多层材料时,则要求层间必须紧密接触,无气泡和气体夹层,容器壁内、外表面应平整。 罐型:卧罐、球罐、立罐、槽罐等。 壁厚:2~70mm; 5.3仪表安装环境 液化气液位计仪表采用隔爆设计,允许的工作环境温度应在-30℃~+55℃范围内。在北部等寒凉地区使用,冬季建议加保温措施;在南部等温度较高、阳光直射强烈的地区,建议安装在阴凉通风处或使用遮阳板,避免仪表因内部温度过高而减少使用寿命。 6.液化气液位计安装及接线 6.1仪表主机安装示意图
