Volumetric flow measurement for electrically conductive liquids, with no moving parts.
Select the measurement range, process connection and output configuration for your application.
The A100 uses electromagnetic sensing to measure liquid flow in closed pipelines. Liner and electrode options allow the wetted materials to be matched to the medium. Analog, pulse and digital outputs connect the measurement to a wider control system. Review conductivity, pipe size and straight-run requirements before selection.
