German E+H Capacitive Level Gauge FMI51 SeriesThe probe can be used for continuous measurement of liquid level, with reliable measurement, especially suitable for media with adhesive formation and extreme high temperature situations. The measured value is independent of the DK value (dielectric constant). E+H FMI51, The German E+H capacitor level gauge FMI51 series is used in conjunction with Fieldgate FXA320 (remote measurement value access using internet technology), and Liquicap provides an ideal inventory management solution.
advantage
For liquids with conductivity greater than 100 μ S/cm, calibration is not required. The probe length is pre-set at the factory at 0%/100%, and debugging is fast and simple.
Text display, menu guided on-site settings (optional).
E+H FMI51, The German E+H capacitor level gauge FMI51 series has obtained various certifications and licenses, with a wide range of applications.
Compliant with IEC 61508 standard, suitable for safety systems that require SIL2 level safety.
The liquid receiving part is made of corrosion-resistant materials and FDA certified materials.
Double overvoltage protection (gas discharge device+protective diode) can prevent tank discharge.
E+H FMI51, German E+H capacitance level gauge FMI51 series electronic components provide built-in adhesion compensation
German E+H Capacitive Level Gauge FMI51 Seriesapplication area
Liquicap FMI51 has a sturdy structure (self sealing cone) and a probe pressure range from vacuum to 100 bar. The temperature range of sealing and isolation materials used for storage tanks can reach -80~+200 ℃. When the conductivity of a liquid is greater than 100 μ S/cm, the measured value is independent of DK (dielectric constant), so there is no need to recalibrate to measure different liquids.
