In the demanding fields of life sciences, biopharmaceuticals, and food processing, precision and hygiene are non-negotiable. The Endress+Hauser Proline Promass P 500 is the benchmark for sterile Coriolis flow measurement. Specifically identified by the product root E&H 8P5B, this remote-type flowmeter is engineered for applications requiring strict compliance with sanitary standards, offering unmatched multivariable measurement (mass flow, density, and temperature) in a compact, drainable design -6.

As a leading supplier, ST-YUKE CO., LIMITED offers the full range of E&H 8P5B series with authentic configurations and expert technical support.

Product Series Overview: The 8P5B Family

The Promass P 500 series is designed for inline installations under sterile conditions. It features a low-ferrite content 1.4435 (316L) stainless steel measuring tube with an electropolished surface, ensuring fast recovery from CIP (Clean-in-Place) and SIP (Sterilize-in-Place) cycles -1-4. The “8P5B” root code specifically denotes the remote transmitter version (P 500) with the sensor, allowing for flexible installation in harsh environments.

The series is divided into five primary sensor sizes to cover a wide range of flow rates:
