Application
The Micropilot FMR540 is designed for commercial custody transfer and inventory control, certified by NMi and PTB, complying with OIML R85 and API 3.1B standards. The parabolic antenna version is ideal for open spaces up to 40m, while the horn antenna suits applications where tank/nozzle geometry prevents parabolic antenna use. Simple, cost-effective installation via 4-wire HART cable with 24V DC intrinsically safe power supply.
Parabolic antenna enables precise measurements in open spaces up to 40m with narrow beam pattern for tanks with side nozzles. The 4″/DN100 horn antenna serves similar applications.
