Urea dispensers use electronic control units to regulate pump speed and flow rate, ensuring precise DEF delivery for SCR systems. Accurate flow control is essential to maintain emission compliance and prevent overfilling or underfilling.
Advanced dispensers continuously monitor flow rate through high-precision meters. Some systems include temperature compensation to account for fluid density changes caused by environmental conditions.
Precise flow control minimizes DEF waste, supports accurate billing, and maintains vehicle SCR system efficiency, providing operational reliability for both fleets and public stations.
