Feature / Type | Rosemount 8800 Vortex Flow Meter | Thermal Mass Flow Meter | Differential Pressure (DP) Flow Meter | Coriolis Mass Flow Meter |
---|---|---|---|---|
Measurement Principle | Vortex shedding frequency proportional to flow | Heat transfer from the heated sensor to the airflow | Pressure drop across orifice/venturi | Direct mass flow via Coriolis force |
Typical Accuracy | ±0.75% of rate (gas/air) | ±1–2% of reading | ±1–2% of full scale | ±0.1–0.5% of the rate |
Best for | Compressed air, steam, and industrial gases | Compressed air, low/medium flow gas | Large pipelines, cost-sensitive compressed air | High-value gases, precise custody transfer |
Maintenance | Virtually maintenance-free (no moving parts) | The sensor may require cleaning | Orifice plates may wear/need replacement | Minimal, but calibration is required |
Installation | Straight pipe runs required (typically 10D upstream, 5D downstream) | Easy, often insertion type | Requires a differential pressure transmitter + primary element | More complex, higher installation cost |
Output / Integration | Digital protocols (HART, Foundation Fieldbus, WirelessHART) | Analog + digital | Analog + digital | Advanced digital outputs |
Relative Cost | Medium | Low to medium | Low to medium | High |
Durability | High, stainless steel body | Moderate (sensor fragile in harsh env.) | High, but pressure loss occurs | High, but sensitive to vibration |
Energy Monitoring | Excellent for compressed air audits and plant optimization | Widely used for compressed air audits | Suitable for utility-level monitoring | Overkill for standard compressed air |
The Rosemount 8800 Series Compressed Air Flow Meter is designed for a wide range of industrial environments where accurate and reliable compressed air measurement is critical. Typical applications include:
Q1: What principle does the 8800 Series use to measure compressed air?
A: It uses vortex shedding technology, where vortices generated by a bluff body are detected and converted into highly accurate flow measurements.
Q2: Is the 8800 suitable for compressed air applications?
A: Yes. The 8800 Series is widely applied in compressed air distribution systems, providing reliable, maintenance-free measurement with no moving parts.
Q3: What is the accuracy of the 8800 for compressed air?
A: Typical accuracy is ±0.75% of rate for gases, making it highly reliable for energy monitoring and process control.
Q4: Does the meter require regular maintenance?
A: No. The 8800 Series is designed to be virtually maintenance-free, with no moving parts to wear out or recalibrate frequently.
Q5: What are the installation requirements?
A: The meter requires straight pipe runs upstream and downstream (typically 10D upstream, 5D downstream) to ensure stable flow measurement.
Q6: Can it integrate with automation systems?
A: Yes. The 8800 supports digital communication protocols such as HART, FOUNDATION Fieldbus, and WirelessHART for seamless integration.
Q7: How does it compare to thermal mass flow meters for compressed air?
A: While thermal mass meters are common for compressed air, the 8800 offers higher durability, no sensor fouling, and better long-term stability, especially in industrial environments.
Q8: What industries typically use the 8800 for compressed air?
A: It is widely used in manufacturing, chemical, pharmaceutical, food & beverage, and utilities for compressed air monitoring and energy optimization.
