Rosemount 8750W Mag Meter – FAQ
Q1: What is the Rosemount 8750W Mag Meter used for?
A1: The 8750W is designed for accurate measurement of conductive liquids in water, wastewater, and utility applications. It is optimized for municipal and industrial water services.
Q2: How does the 8750W Mag Meter work?
A2: It uses Faraday’s Law of Electromagnetic Induction. As conductive liquid flows through a magnetic field inside the meter, a voltage is induced and measured, which is proportional to the flow rate.
Q3: What are the main advantages of the 8750W?
A3:
- No moving parts, minimizing maintenance
- High accuracy and repeatability
- IP68-rated coil housing for harsh environments
- Advanced diagnostics and meter verification features
Q4: What types of fluids can the 8750W measure?
A4: It can measure any conductive liquid, including potable water, wastewater, slurries, and industrial process water. It is not suitable for non-conductive fluids such as oils or gases.
Q5: What installation styles are available?
A5: The 8750W is available in flanged configurations, making it compatible with standard water and utility piping systems.
Q6: How does the 8750W compare to other Rosemount Mag Meters?
A6:
- 8705 → General-purpose industrial use
- 8711 → Compact, lightweight wafer design
- 8721 → Sanitary applications (food, beverage, pharma)
- 8750W → Specialized for water and utility services
Q7: Does the 8750W require frequent calibration?
A7: No. The 8750W is factory-calibrated and designed for long-term stability. Built-in diagnostics help verify performance without requiring the meter to be removed from service.
