Used Rosemount 8750W DN250 Magnetic Flow Meter

Introduction

Rosemount 8750W DN250 magnetic flowmeter is a highly reliable and accurate device designed to measure the flow of conductive fluids in large-diameter pipes. Suitable for industrial applications requiring accurate and continuous flow measurement, this meter offers high performance even under harsh operating conditions. We'll examine in detail the technical specifications, features, and recommendations for purchasing a used meter of this type.

Construction and Components

The Rosemount 8750W DN250 is composed of several key components that ensure its reliability and accuracy:

• Meter Body : Made of stainless steel or special alloys, designed to withstand severe environmental and chemical conditions.
• Electrodes : Made of highly corrosion-resistant materials, such as tantalum or platinum, which ensure precise measurement of fluid flow.
• Measuring Coils : They use the principle of electromagnetic induction to determine the velocity of the fluid through the pipe.
• Display and Control Unit : Equipped with a digital display that shows flow readings and a control unit that operates and calibrates the meter.

The main dimensions of the Rosemount 8750W refer to the nominal diameter DN250, which indicates a pipe diameter of 250 mm.

Technical Characteristics

• Measuring Principle : Measurement based on electromagnetic technology, which is particularly suitable for conductive fluids.
• Nominal Diameter : DN250, compatible with pipes with an internal diameter of 250 mm.
• Construction Materials : Stainless steel, tantalum, platinum, or other corrosion-resistant materials, as per model specifications.
• Measuring Range : Suitable for flows of different flow rates, with the possibility of measuring even at low fluid velocities.

Use and Procedure

To use the Rosemount 8750W Magnetic Flowmeter , follow these steps:

1. Installation : Place the meter inside the pipeline ensuring that it is mounted correctly and that the fluid flow is uniform at the inlet and outlet of the meter.
2. Connection : Connect the meter to the electrical grid and control systems, if applicable. Verify that all connections are secure and leak-free.
3. Setup : Use the control unit to configure the meter based on fluid characteristics and application specifications. Set the units of measurement and calibrate the device if necessary.
4. Monitoring : Read flow data on the digital display and check readings regularly to ensure the meter is working properly.

Matching accessories

Accessories compatible with the Rosemount 8750W include:

• Filters and Separators : To protect the meter from solid particles and contaminants in the fluid.
• Temperature Sensors : To monitor and compensate for fluid temperature variations.
• Transmission Unit : To integrate flow data with remote monitoring and control systems.

Maintenance and Control Used

To keep your Rosemount 8750W in good condition:

1. Regular Cleaning : Clean the sensors and electrodes to remove any buildup of deposits or contaminants.
2. Calibration : Perform periodic calibration of the meter to ensure continued accuracy in flow readings.
3. Component Inspection : Regularly check the condition of the components and check for any signs of wear or damage.

To determine if a used meter is in good condition, check the cleanliness of the electrodes, the accuracy of the readings, and any signs of wear on the body and components.
