Metering Equipment BS4
This BS4-compliant metering module regulates urea flow with precision valves, ensuring accurate dosing according to engine load and exhaust temperature. Built with corrosion-resistant materials, it prevents crystallization, clogging, and pressure fluctuations within the urea supply system. Its robust design supports consistent dosing performance, even in harsh operating environments and varying temperature conditions.
By ensuring correct urea injection, the metering equipment enhances SCR efficiency, reduces NOx emissions, and helps maintain BS4 emission compliance. It improves overall system reliability, prevents fault codes, and contributes to longer service intervals in commercial diesel vehicles.
