Diesel Exhaust Fluid

Diesel Exhaust Fluid (DEF) is a 32.5% high purity urea and de-ionized water solution, considered a Fertilizer by the National Conference of Weights & Measures.

The EPA has required commercial engine and vehicle manufacturers to lower emissions and increase performance standards in 2010. One technology that provides a reliable solution is the Selective Catalytic Reduction (SCR), a system that sprays a fine mist of emission fluid that is dosed into the exhaust to react and neutralize the NOx molecules.

With an economical 304 stainless steel construction, our 682 piston and 700 rotary flow meters are manufactured to maintain the high purity required for the handling of DEF (ISO 22241-1). As one of the ONLY flow meters available today to meet the custody transfer requirements of DEF measurement, we look forward to help drive solutions for cleaner air.
