OTT RLS - Radar Level Sensor 雷達水位計
產品編號：
Non-contact water level sensor for long term surface water measurements 適用於長期測量地表水位之非接觸式水位感測器
The OTT RLS is a non-contact radar level sensor with pulse radar technology. The OTT RLS offers a large measurement range with a small blanking distance and narrow beam width and it easily connects to most dataloggers. The RLS has extremely low power consumption and is ideal for remote or solar powered sites. OTT RLS採用脈衝雷達技術，為非接觸式雷達液位感測器，測量範圍廣，消隱距離小，波束寬度窄，可輕鬆連接大多數的資料記錄儀。極低功耗，是偏遠站點或藉由太陽能供電的站點的節能理想選擇。
高效能 - 測量不受氣溫、濕度、洪水事件、漂浮物或污染水的影響； 減少漏失數據的可能性並減少數據後處理
低維護量 - 扁平式天線設計消除昆蟲的築巢區和定期維護要求
靈活整合/設定容易 - 透過標準通訊介面、SDI-12 或 4 ... 20 mA 連接到大多數數據記錄器； 無需額外的 PC 軟體
安裝簡單 - 輕巧精實設計可輕鬆安裝於橋樑、擴展安裝支架或小型保護外殼內

For surface water level measurement of:
- Streams and rivers
- Tidal zones
- Reservoirs and lakes
Ideal for monitoring:
- Surface waters prone to flooding
- Sediment or debris laden streams and rivers
- Migrating channels
Advantages:
- No drift over time
- High Performance–Measurements are unaffected by air temperature, humidity, flood events, floating debris, or contaminated water; reduces the likelihood of missing data and reduces data post processing
- Low Maintenance–Flat antenna design eliminates nesting areas for insects and periodic maintenance requirement
- Flexible Integration/Easy Setup–Connects to most data loggers via standard communication interfaces, SDI-12 or 4 ... 20 mA; no need for additional PC software
- Simple Installation–Light weight compact design facilitates easy mounting on bridges, extension mounting bracket or inside a small protective housing
- Low Profile Design–Unobtrusive appearance is ideal for urban installation sites or sites prone to vandalism
- Low Power Consumption–Ideal for remote or solar powered sites; requires only 12 mA when active
