摘要
YSJ-1 型油水界面检测仪是一种用核物理方法检测油水分离罐中油水分界面高度和液面总高度的新型仪表。它采用了非线性拟合、放射源衰变自动补偿、介质温度—密度自动补偿等多项技术,具有非接触测量、抗结蜡和维修量小等常规仪表不可比拟的优点。测量范围:液面总高度 0—200cm,油水分界面高度 0—100cm;测量精度:液面总高度为1%,油水分界面高度为2%;反应时间:≤10s;长期稳定性:≤0.5%量程/48h;温漂:≤0.01%量程/℃。该检测仪主要应用于油田生产中油水分离罐的油水分界面高度和液面总高度的检测,也可用于其它场合存储罐中两种不同液体的分界面高度和液面总高度的检测。
A new type nuclear device for measuring the oil-water interface level as well as the total liquid level was presented. A series of new methods, such as non-linear fitting of the level, automatic compensations for the deviation caused by the decay of radioactive source, the medium’s temperature, etc., were employed. Comparing with other non-nuclear techniques, this device has the following advantages: non-contact surveying, anti-interference of paraffin wax coagulating and a little of repairing. The measuring range is 0—200cm for total liquid level and 0—100cm for oil-water interface level respectively. The measurement precision is 1% for total liquid level and 2% for the interface level respectively. The respond time is ≤10s, the long time stability ≤ 0.5% FS / 48h and the temperature influence ≤0.01% FS /℃. The gauge can be used in surveying oil-water interface level and total liquid level in oil-water separation tanks on oil fields. It is also suitable to measure the interface level of two kinds of liquids as well as the total liquid level in various storage tanks.
