MEAS QLS RC Series Adblue DEF Intank Level and Quality Sensor


MEAS announces QLS RC Series Adblue DEF Intank Level and Quality Sensor. The quality sensor directly and simultaneously measures the chemical properties of aqueous urea solution. Utilizing an optical NIR technology, the measurements of urea concentration and temperature enable users to determine if the quality of employed reducing fluid will enable SCR systems to achieve optimal performance.

In tank real time urea analysis allows high performance algorithm to provide both SCR system protection by differentiating unauthorized fluids and direct feedback to urea feed control systems or ECMs to optimize emission control for NOx reduction. The quality sensor is an important tool for meeting regulated OBD compliance to confirm urea presence and concentration and security signal communication. A universal digital CAN J1939 compliant protocol provides easy to connect interface to main control systems (i.e., ECM, SCR feed control, OBD bus). A simple 4 pins connector allows cost effective mounting options.

From our range of Adblue DEF sensors which offer design engineers reed switch reliability, the QLS RC Series design allows for sensing liquid level along with Adblue DEF temperature and quality. It is available in a range of customizable lengths and resistance value outputs to meet your specific tank requirements.

Applications include:
- Adblue DEF level sensing
- Adblue DEF temperature sensing
- DE Adblue F quality sensing
- Bus and truck
- Engines
- Off-highway vehicles
