文档介绍：Technical InformationMicropilot S FMR540Level-RadarSmart Transmitter for continuous and non-contact precision level measurement. For custody transfer and inventory control applications with NMi and PTB Micropilot S is used for highly accurate level measurement in storage tanks and can be applied in custody transfer applications. It meets the relevant requirements according to OIML R85 and API areas of application are:? The Micropilot S with parabolic antenna is excellently suited for free space applications up to 40 m (131 ft).? The Micropilot S with horn antenna is suitable for free space applications that disallow the use of a parabolic antenna due to tank/nozzle FMR540 with a DN200 (8") or DN250 (10") parabolic antenna offers high beam focussing of ° or ° respectively, and is therefore ideally suited to applications with nozzles situated close to the tank FMR540 with DN100 (4") horn antenna is designed for all small nozzles benefits? Better than 1 mm accuracy.? National approvals (NMi, PTB) for custody transfer.? Applicable as stand-alone system or tied into tank gauging systems via the Tank Side Monitor NRF590.? Cost-effective and simple installation via 4-wire cable with HART and 24V DC intrinsically safe power supply.? low cost, low weight UNIversal flanges? alignment device pensate any flange inclination? easy on-site operation via menu-driven alphanumeric display? missioning, documentation and diagnostics via operating software (ToF Tool - Fieldtool Package or FieldCare)?
