A flow meter capable of measuring blow-by flow rate without being affected by the density or viscosity of the fluid.

The "SBM-2200" is a flow meter designed to measure the flow rate of blow-by gas (blow-by) that enters the engine's crankcase. Measuring blow-by flow is used as a means to understand the wear conditions of piston rings, valve sleeves, and cylinders. This product utilizes the principle of Kármán vortex, allowing for the measurement of blow-by flow without being affected by the density or viscosity of the fluid. 【Features】 ■ Does not select the physical properties or gas composition of the fluid being measured (however, it is not compatible with hydrogen engines) ■ Can measure gas flow even in the presence of liquid droplet contamination ■ Simple structure and easy maintenance *For more details, please refer to the PDF materials or feel free to contact us.
