Capacitance Level Measurement Liquicap FMI21

Brand: Endress+Hauser
Fundamental Fundamental

Liquicap FMI21 is a simple and cost-effective rod probe for continuous level measurement for conductive liquids. High quality non-corrosive materials (carbon fibre, stainless steel) make it suitable even for aggressive liquids (e.g. acids and alkalis).

Used in conjunction with the Fieldgate FXA320 (remote measured value interrogation using Internet technology), Liquicap is an ideal solution for Inventory Management Solutions.

The device is preconfigured from factory 0 to 100% to probe length ordered. It can be used as of a conductivity of 30 μS/cm and the measurement is independent of the dc-value (dielectric constant) of the liquid. Suited for cistern measurements.
