在工业生产中,物位的检测与控制占有很重要的地位,物位计的种类很多,例如:直读式玻璃管液位计,浮标式、差压式液位计,电容式、电感式、电阻式和机械式物位计,近年来又有高频、超声、激光物位计等。 γ射线料位计是一种非接触式物位计,它安装简单、运行可靠、维修方便,特别适用于下列其它物位计难以应用甚至不能应用的场合:高温、高压、真空、旋转密闭容器;易燃、易爆、易结晶、高粘度、强腐蚀、无定形、极毒、熔融、轻质粉末等物料;二相界面、分层界面以及多尘、多烟雾、强干扰等恶劣环境。因而γ射线料位计在化工、水泥、冶金、炼焦、矿山、轻纺、食品等部门得到广泛的应用。
In industrial production, level detection and control occupy a very important position, there are many types of level gauge, such as: direct-reading glass tube level gauge, buoyancy, differential pressure level gauge, capacitive, inductive , Resistance and mechanical level meter, in recent years there are high-frequency, ultrasound, laser level meter and so on. γ-ray level meter is a non-contact level meter, it is simple to install, reliable operation, easy maintenance, especially for the following other level gauge is difficult to apply or even can not be applied to the occasion: high temperature, high pressure, vacuum, rotary closed container ; Inflammable, explosive, easy to crystallize, high viscosity, strong corrosion, amorphous, extremely toxic, molten, light powder and other materials; two phase interface, layered interface and dust, smoke, strong interference and other harsh environments. Thus γ-ray level gauge in the chemical, cement, metallurgy, coking, mining, textile, food and other departments have been widely used.
