The Endress+Hauser 8E3B25 (Promass E 300, DN25/1") is a cost-optimized yet highly accurate Coriolis mass flowmeter designed for demanding oil & gas, refining, and chemical applications. Delivering ±0.10% mass flow and ±0.0005 g/cm³ density accuracy, it is fully certified for custody transfer (MID MI-005, OIML R117) and fiscal metering. Heartbeat Technology provides continuous self-diagnostics and traceable in-situ verification without process interruption. With a compact dual-compartment transmitter, HART/Modbus/Ethernet-APL, and optional Bluetooth, the 8E3B25 sets the benchmark for reliable hydrocarbon measurement in transfer, allocation, and loading operations.
