High resolution, bi-directional, and quadrature signal outputs make Max Piston Flow Meters the choice in measuring low flows, rapid valve cycling, and chemical injection.
Max Piston Meters are not sensitive to changes in flow profile, fluid density, or viscosity. No straight pipe runs or flow conditioners needed.
Choose from frequency or analog transmitter options. High temperature models up to 225°C available. CE Certified, Ex-proof version available with ATEX/IECEx and UL/cUL certifications.
