HYDROSTATIC LEVEL METER Hydrostatic level meter Hydrostatic level meter FST-700 is compact measuring device containing silicon strain gauge sensor and evaluation electronics in stainless steel probe. From the probe housing comes out 2-wire cable with capillary (for atmospheric pressure compensation). For continuous level measurement of non-aggressive liquids without gross (solid) impurities in non-pressure tanks, boreholes, wells, reservoirs and swimming pools. Suitability for other than water liquids are advised to consult with the manufacturer. Installation is done by hanging the probe down into the measured area (tanks, boreholes). The probe is left hanging on the cable, or is placed on the bottom. • • Tutti i dati ed i contenuti di questa scheda sono di proprietà esclusiva di Riels Instruments The cable includes an air compensation tubing (capillary), so the connection must be done in non-hermetic junction box. In tanks where there are strong turbulences or waves, the probe should be placed in the stilling tube, behind the wall, or at least at the maximum possible distance from the source of turbulence. When using other liquid than water it is needed to make the output correction with respect to the density of the liquid, eventually consult the applicationwith the manufacturer. Moisture-proof, anti-sweat, free of leakage troubles, IP68 Excellent resistance against impact, overload, shock and erosion Efficient lightning protection, strong anti RFI&EMI protection Advanced digital temperature compensation and wide working temperature scope High sensibility, high accuracy, high frequency response and long term stability Applicable Scope • • • • • Building Automation System and constant pressure water supply system Urban water supply and wastewater treatment Liquid-level testing and control in other automation systems Liquid-level testing and control in industrial process Testing and control in Hydraulic and hydropower engineering Electrical connection
