Product Critical Technical Advantages
-
Highest Compliance with Industry Standards: The sensor is fully conformant to ASME BPE, 3-A, and EHEDG requirements. With a measuring tube made of 1.4435 (316L) stainless steel and low delta ferrite content, it prevents product contamination and ensures the highest level of material traceability and hygienic safety.
-
Fast Recovery from CIP/SIP: Designed to withstand the thermal shocks of Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP) cycles, the Promass P recovers its high-precision measurement capability almost immediately. This minimizes downtime between batches and maximizes production efficiency in biotech facilities.
-
Precision Electropolished Surface: The internal measuring tube features a high-grade electropolished finish, which reduces surface roughness to a minimum. This prevents protein adhesion and bacterial growth, ensuring that the meter remains easy to clean and maintains a sterile process environment.
-
Integration of Operational Intelligence through Heartbeat Technology: This system provides continuous internal diagnostics and documented verification that complies with regulatory requirements. Heartbeat Technology enables process safety at all times by verifying the meter’s health without interrupting sterile production runs.
-
Full Access to Process and Diagnostic Data: The Proline 300 transmitter offers a compact dual-compartment housing with up to 3 freely combinable I/Os and integrated WLAN. This allows operators to perform commissioning and monitoring wirelessly, reducing the need for physical contact with the device in cleanroom environments.
-
Space-saving Installation and Multivariable Output: By delivering simultaneous data for mass flow, density, and temperature, the Promass P 300 reduces the number of process measuring points. Since the Coriolis principle requires no straight inlet or outlet piping runs, it can be integrated into tight modular skids without compromising accuracy.
