ข้อได้เปรียบทางเทคนิคที่สำคัญ
-
Non-Invasive Measurement: Since the sensors never come into contact with the medium, there is no risk of corrosion, abrasion, or pressure loss. This makes the P 500 perfect for retrofitting into existing systems without cutting pipes or stopping production.
-
FlowDC for Minimal Inlet Runs: Standard ultrasonic meters typically require long straight pipe runs to manage disturbed flow profiles. The integrated FlowDC (Flow Discharge Check) function mathematically compensates for flow disturbances, maintaining specified accuracy with an inlet run of only 2 x DN.
-
Maintenance-Free Coupling: Traditional clamp-on meters require periodic re-greasing of the sensors. The P 500 uses specialized solid coupling pads that provide permanent acoustic contact, ensuring maintenance-free operation for the entire life cycle of the device.
-
Extreme Temperature Range: While most clamp-on systems are limited to moderate temperatures, the P 500 offers specialized sensor sets capable of measuring liquids up to 550 °C (1022 °F), essential for heat transfer fluids and refinery applications.
-
Functional Safety (SIL): Developed according to IEC 61508, the P 500 is suitable for use in SIL 2 and SIL 3 safety-instrumented systems, providing a high level of functional safety for critical processes.
-
Heartbeat Technology: This suite provides continuous diagnostic coverage. It can even detect internal pipe build-up (scaling or fouling) by monitoring changes in signal strength and sound velocity, allowing for predictive maintenance before the process is affected.
