Immersion Hydrostatic Liquid Level

Product Description

The WLI100 is a drop-type hydrostatic level transmitter designed to measure liquid levels (e.g., wastewater, water, fuel oil) by detecting hydrostatic pressure proportional to the liquid height. It uses a ceramic piezoresistive sensing element with temperature compensation and linearity correction, converting pressure into a 4–20mA DC output signal. The sensor is immersed directly into the liquid and can be installed via flange or bracket, offering ease of use and high reliability.

Key Features

• High Precision & Stability: 0.2% or 0.5% accuracy (default 0.2%).
  
• Easy Installation: Direct immersion into the liquid; no complex setup.
  
• Robust Design: Solid-state, no moving parts, resistant to bubbles/deposits.
  
• Wide Compatibility: Measures liquids from water to viscous oils (non-corrosive to 316L stainless steel).
  
• Output: Standard 4–20mA DC for RTU/PLC integration.
  
• Protections: Power reverse polarity and overload current limit protection.
  
• Temperature Range: Operates in -20°C to 80°C environments.
  
• IP68 & Explosion-Proof: Rated Exia II CT6 for harsh conditions.

Typical Application Scenarios

• Water/Wastewater Management: Tanks, reservoirs, or treatment plants.
  
• Fuel Storage: Monitoring diesel/oil levels in industrial tanks.
  
• Industrial Processes: Liquid level measurement in chemical or manufacturing systems.
  
• Flow Control: Installation in pipes/tubes for dynamic liquid measurement (with perforated tubes to reduce flow interference).
