FMG72B Model OptionsView all models
Edit these specs to order a different model. Not all combinations are valid. Options compatible with previous selections will be in bold.
*Highlighted options are not compatible. Please select a different combination.
Changes of temperature, density, viscosity, concentration or electrical conductivity (minimum conductivity of 50 µs/cm) of the fluid do not affect the output signal.
FMG70B series can be used in areas where flow sensors with moving parts e. g. paddle wheel sensors, cannot be applied due to contamination/particulate in the media. The sensor is intended for continuously measuring of flow rates or for dosing/batching of electrically conductive liquids (minimum conductivity 50 S/cm). The output signal frequency (or current) is proportional to the flow. Two options are available for output signals, frequency or analog (-A models).
