644-8189: Diesel Exhaust Fluid Level Indicator

Cat® Diesel Exhaust Fluid level indicator is a device that monitors the amount of diesel exhaust fluid (DEF) in the reservoir tank of vehicles that use selective catalytic reduction (SCR) technology to reduce harmful emissions. DEF is a solution of urea and water that is injected into the exhaust stream of diesel vehicles to transform nitrogen oxide (NOx) emissions into harmless nitrogen and water. The diesel exhaust fluid level indicator consists of a sensor that measures the fluid level in the tank and a warning system that alerts the driver when the fluid level is low or when there is a problem with the DEF system. If the fluid level drops below a certain threshold, the vehicle may enter a reduced power mode or limit its speed to prevent further damage to the engine and the environment. The diesel exhaust fluid level indicator is an important component of the engine’s emission control system. It helps the operator to maintain optimal performance and fuel efficiency, as well as comply with the emissions standards. The operator should check the fluid level regularly and refill it when needed, using only certified DEF products. Cat® Parts are manufactured to precise specifications and are built for durability, reliability and productivity. Application: Cat® Level Indicator is used in the diesel exhaust fluid reservoir tank of Cat® Machines. Consult your owner's manual or contact your local Cat® Dealer for more information.
