Confirm the liquid and 压力 reference
A submersible 压力-based 液位 arrangement must be evaluated with the actual liquid and vessel conditions. Provide density information where known and identify whether the tank is open or pressurized. Do not assume an open-tank 液位 configuration can be transferred unchanged into a closed vessel with 压力 above the liquid surface.
Specify the installation depth and cable
Give the maximum 液位 above the 传感器, mounting depth, cable route and required cable length. Review how the 传感器 will be lowered, supported and retrieved. Ask for the cable handling and reference-vent instructions applicable to the selected model. Protect the cable and termination as specified rather than assuming immersion protection covers every connection point.
Check compatibility and mechanical exposure
The SL09A catalogue lists a stainless-steel 传感器 and submersible construction. Confirm compatibility of all wetted parts, including cable materials, with the liquid and 温度. Describe sediment, moving equipment and filling currents. Arrange a position that can be inspected and maintained without leaving the 传感器 exposed to avoidable mechanical contact.
Define the measurement reference at acceptance
Document the 传感器 elevation, zero reference and how the receiver converts the signal to 液位. Compare the indication at an accessible known 液位 and record the liquid condition used for that check. Keep the range and cable specification with the order so a replacement 仪表 can be reviewed against the same installation.
确认介质与压力参考
基于压力的投入式液位测量需结合实际液体与容器条件评估。已知时提供密度，并说明敞口还是带压容器。不能将敞口罐配置未经核对直接移用于液面上方存在压力的密闭容器。
明确安装深度和线缆
提供传感器上方最高液位、安装深度、线缆路径和长度，核对下放、固定和取出方式，并索取该型号适用的线缆及参考通气说明。应按要求保护线缆和端接，不能将浸水防护等级扩大解释到所有接线位置。
核对兼容性与机械环境
SL09A 样册列有不锈钢传感器与投入式结构。需核对包括线缆在内的全部接液部件与液体、温度的兼容性，并说明沉积物、运动设备和进水流。应兼顾可检查维护和避免机械碰撞。
验收时定义测量参考
记录传感器标高、零点参考及接收端信号换算方式，在可核对液位下比对读数并记录液体条件。将量程和线缆规格随订单保存，方便备件按相同安装条件核对。
