Flow Rate Calculator


We offer a variety of flow restrictor models which customers can select from, based on factors including the restrictor’s orifice size or the desired flow rate. While all products can be customized to meet your application requirements, our engineers have developed a helpful flow rate calculator that allows users to estimate the expected flow rate provided by each standard KOENIG RESTRICTOR® model.

Enter some basic information into our Flow Rate Calculator form below to identify the flow rate in liters/minute. Alternatively, please use our Orifice Size Calculator to determine the correct part based on the orifice size. For support please contact us, or request a quote for a Series RE flow restrictor for your application.
