API液位开关UTS系列介绍
UTS™ 的工作温度范围为 -55°C 至 +100°C，设计用于海船和内河船舶、油轮、化学品船、天然气运输船和海上钻井平台的货舱、油井和服务罐的液位检测。
UTS™ 的工作原理基于特有的声波技术，可在极端工作温度下提供优质的结果。 无论罐的形状、液体类型或液体温度如何，都能确保测量的准确性。
主要特点：
- 任何类型的液体
- 罐内只有一根钢棒（外部的电子设备和连接）
- 无活动部件
- 无需维护
- 对泡沫不敏感
The UTS™ has operating temperature range of -55°C to +100°C and is designed for level detection in cargo holds, wells and service tanks in sea and river ships, oil tankers, chemical tankers, gas carriers and offshore drilling platforms.
The operating principle of the UTS™ is based on a breakthrough patented acoustic wave technology, providing outstanding results in extreme operating temperature. The accuracy of measurement in ensured regardless of the shape of the tank, type of liquid or liquid temperature.
Main features:
- Any type of liquid
- Only a steel rod inside the tank (electronics and connections outside)
- No moving parts
- No maintenance required
- No sensitivity to foamt
