API液位开关TLA系列介绍
TLA用于检测储罐中的高液位 (95%) 和高高液位 (98%)。 TLA安装在油轮、天然气运输船、浮式储存库、FSO、FPSO、陆上石油、石油产品和液化气储罐的甲板上。 TLA基于与 UTS相同的声波专利技术，具有高水平的准确性、可靠性和可定制性。 TLA是一种两点液位开关，其警报级别由杆的长度定义，可根据要求生产。 内置测试按钮用于在填充液体之前根据船级社的要求执行功能测试。
The TLA is used for the detection of high (95%) and high-high (98%) levels in tanks. The TLA is installed on the deck of tankers, gas carriers, floating storages, FSO, FPSO, onshore storage tanks for oil, petroleum products and liquefied gas. Build on the same patented acoustic wave technology as UTS, TLA features a high level of accuracy, reliability and customizability. The TLA represents a two-point level switch with alarm levels defined by the length of rods, which are produced on request. Built-in test buttons are used for performing a functionality test before filling the liquid, in accordance with the requirements of classification societies.
