Endress Hauser FMI51-A1BASJA4A1A Capacitance Level measurement Liquicap FMI51

Liquicap FMI51 is a reliable fully insulated rod probe for continuous level monitoring in liquids, particularly in build-up forming media and extremely high temperatures. The measurement is independent of the dielectric constant (dc). Used in conjunction with Fieldgate FXA320 (remote measured value interrogation using Internet technology), Liquicap is an ideal solution for Inventory Management Solutions.
