Ensure efficient management of DEF in your fleet with the lmp307 submersible level sensor. Accurate, reliable, and compatible with diesel exhaust fluid.
This tailored version of the LMP307 submersible level sensor is used to measure the level of diesel exhaust fluid in storage tanks. This makes it ideal for use in fleet depots and other settings where diesel vehicles are serviced and maintained. The sensor provides accurate and reliable level measurement, enabling efficient inventory management and preventing costly downtime due to DEF shortages.
Diesel exhaust fluid (DEF), is a crucial component in modern diesel engine emission control systems. It is injected into the exhaust stream, where it helps to convert harmful nitrogen oxides (NOx) into harmless nitrogen and water vapor. This process, known as Selective Catalytic Reduction (SCR), significantly reduces the environmental impact of diesel engines.
The LMP307 sensor’s compatibility with DEF is a key feature. This fluid, being an aqueous urea solution, can be corrosive to some materials. However, the LMP307‘s stainless steel construction, specifically 316L grade stainless steel for both the housing and diaphragm, ensures long-term durability and resistance to the corrosive effects of DEF.
Furthermore, the sensor’s FKM seals are specifically chosen for their compatibility with DEF up to 70degC, preventing leaks and maintaining the integrity of the measurement system. This is particularly important in submersible applications where the sensor is in constant contact with the fluid.
In addition to fleet depots, the LMP307 level sensor can be used in various other applications, including:
- Bulk DEF storage facilities: Monitoring inventory levels in large storage tanks.
- DEF dispensing systems: Ensuring accurate dispensing and preventing overfills.
- Mobile DEF refilling units: Providing accurate level measurement in mobile applications.
- SCR system monitoring: Integrating with SCR systems to monitor DEF consumption and trigger alerts for low levels.
