8F3B25‑BDDBAEAFABSAAASAA2+AA is Proline Promass F 300 Coriolis mass flowmeter from Endress+Hauser. It implements Coriolis measuring principle, simultaneously measuring mass flow, volume flow, density and medium temperature without inlet straight pipe requirements. It supports Heartbeat Technology for continuous self‑diagnosis and in‑situ device verification, reducing recalibration cycles. The dual‑compartment transmitter housing supports multiple configurable I/O interfaces and touch‑operated backlit display with WLAN access. Wetted parts adopt high‑grade corrosion‑resistant stainless steel material, adapting to harsh chemical, oil‑gas and food‑grade process conditions. It delivers stable high‑precision measurement independent of medium viscosity, density and flow profile. Suitable for new project installation, field spare‑part replacement and process retrofit jobs in process industries。
