In modern commercial vehicles, compliance with emissions standards depends largely on the proper functioning of the exhaust aftertreatment system. One of the key components in this process is the urea flowmeter, responsible for monitoring the AdBlue liquid level and ensuring an adequate supply to the SCR (Selective Catalytic Reduction) system.
En Ryme Automotive We supply flow meters that stand out for their reliability, durability and compatibility with the main brands on the market such as DAF, Volvo, Iveco, MAN, Mercedes-Benz, SAF y Scania. Our specialized catalog is available through the B2B Customer Portal, with advanced search by OEM references and a large stock for immediate delivery.
How does a urea flowmeter work?
The gauge uses a float mechanism that varies its position depending on the urea level in the tank. This variation translates into an electrical signal that is transmitted to the vehicle's control unit, allowing the driver to receive an accurate reading of the level.
The sensor's resistance is variable and can be checked directly with a multimeter, which is common practice in technical diagnostic processes.
Thermal design optimized for low temperatures
One of the differentiating elements of our flowmeters is their helical design in certain versions, which allows actively heat the ureaThis is crucial, as AdBlue solidifies at temperatures below -11°C. The spiral design accelerates defrosting and protects the system from adverse environmental conditions.
In models without spiral, the integrated temperature sensor It is responsible for activating external resistors when the temperature drops below a critical threshold, thus preventing the fluid from freezing.
Integrated filters: protection against impurities
Many of our flow meters incorporate filtering systems, which fulfill an essential function: prevent the entry of polluting particles in the system. The most common fault related to the flowmeter is the filter blockage, commonly caused by crystallization of AdBlue upon contact with air.
To avoid malfunctions and ensure the correct flow rate, it is recommended replace the filter according to the established maintenance intervals. It is also crucial to check that there are no leaks in the system.
