Start with the tank drawing
Provide tank height, the highest and lowest operating levels, roof or open-top arrangement and the available mounting position. State whether the result should be level, distance or calculated volume. A level transmitter measures at a defined reference; a volume display additionally needs the vessel geometry or a verified tank table.
Compare contact and non-contact installation
UL550A ultrasonic and RD08A radar products are starting points for reviewing a top-mounted non-contact arrangement. The SL09A is a submersible option where a wetted installation can be considered. Check access for installation and retrieval, tank obstructions, cable routing and the expected condition of the water rather than choosing by tank height alone.
Identify process conditions that need review
Describe turbulence, filling jets, surface foam, condensation and any changing liquid composition. Include a sketch showing ladders, braces and pipes near the measuring path. For a submersible arrangement, confirm liquid compatibility, density assumptions and cable protection. For a top-mounted instrument, confirm its near-range limit against the highest level.
Specify the output and acceptance checks
Send the PLC input type, power supply, cable length and any separate alarm requirement. Agree the empty and full reference levels before configuring the instrument. Compare readings at accessible known levels during commissioning. The monitoring measurement should not be assumed to provide an independent overfill protection function without a separate system assessment.
从罐体图纸开始
提供罐高、最高与最低运行液位、顶盖或敞口形式及安装位置。明确显示液位、距离还是换算容积。液位测量需要明确参考点；容积显示还需要容器几何信息或已核对的罐容表。
对比接触式与非接触式安装
UL550A 超声波与 RD08A 雷达可用于核对顶部非接触安装思路；允许接液安装时，可进一步核对 SL09A 投入式方案。不能只按罐高选型，还需考虑安装与取出空间、内部障碍物、线缆路径和水质。
列出需要核对的工况
说明液面扰动、进水冲击、泡沫、冷凝及液体组分变化，并画出测量路径附近的梯子、支撑和管道。投入式需核对介质兼容性、密度假设及线缆保护；顶部安装需将近端测量限制与最高液位对应核对。
明确输出和验收检查
提供 PLC 输入类型、电源、线缆长度及独立报警需求。设置前约定空罐和满罐参考值，调试时用可核对液位进行比对。监测仪表不能未经系统评估就视为独立的防溢流保护装置。
