- Consider using Siemens SITRANS FM520, MAG 5100W, MAG 3100, or MAG 8000 when faced with challenging installation conditions. These meters can outperform other flow technologies without the need for extensive straight runs of piping.
Maintenance:
- Regularly inspect and clean the meters to ensure proper functionality and accurate measurements. Refer to the user manual for maintenance instructions.
Contact Information:
- For further assistance or inquiries, contact Siemens Industry, Inc. at 1-800-365-8766.

FAQs

Q: Can the meters withstand exposure to harsh chemicals?
- A: Yes, the FM520, MAG 5100W, MAG 3100, and MAG 8000 are designed to withstand exposure to a wide range of harsh chemicals commonly found in water-based applications.
Q: Are these meters suitable for remote pumping stations?
- A: Yes, the MAG 8000 is ideal for applications in remote locations where external power is not available, such as remote pumping stations and field irrigation.
Q: What is the accuracy level of these meters?
- A: The meters offer high accuracy levels of up to 0.6%, making them reliable for precise measurements even in challenging conditions.

PROCESS INSTRUMENTATION

Ideal for challenging installations
Trust the SITRANS FM520, MAG 5100W, MAG 3100 and MAG 8000 for proven accuracy in non-standard pipe configurations. usa.siemens.com/mag.

The SITRANS FM520, MAG 5100W, MAG 3100 and MAG 8000 electromagnetic sensors from Siemens rise to virtually any challenge faced in the measurement of water and wastewater.
The FM520, MAG 5100W and MAG 3100 are traditional externally powered electromagnetic flow meters designed for conductive liquid applications.
The MAG 8000 is ideal for applications where external power is not available, such as remote pumping stations and field irrigation.
Designed for highly accurate measurement in low-flow conditions, these meters also stand up to direct burial, constant flooding and the wide range of harsh chemicals found in water-based applications in many different industries.

Performance Results

Results

A reference test was first conducted by installing the FM520/MAG 5100W, MAG 3100 and MAG 8000 as recommended by Siemens for the best possible performance, with 5D upstream pipe and 3D downstream pipe from the sensor. The meters were then tested in configurations that did not meet the suggested installation conditions. The results were consistent enough to allow acceptance by an independent agency to allow meters with these installation variations to provide an accuracy of 0.6% even with zero diameters upstream and downstream of straight run pipe.

This makes them a great choice for installations where other meters can’t perform due to the lack of sufficient straight runs in approach and retreat piping.
The bottom line: no matter how demanding your mag meter installation may be, you can rely on the FM520, MAG 5100W, MAG 3100 and MAG 8000 to get the job done right.
There is no substitution for installing a flow meter following the guidelines for optimal performance. However, with a homogeneous fluid, when the optimal mechanical piping conditions don’t exist or when the modification of the process piping is cost-prohibitive, the ability to mount a meter in less than optimal conditions can offset the reduction in performance to 0.6%.
SITRANS FM520, MAG 5100W, MAG 3100 and MAG 8000 have been independently confirmed to operate in a variety of non-optimal piping arrangements and still provide acceptable accuracy while maintaining their exceptional repeatability specification.
Other flow technologies, both solid state (no moving parts) and mechanical (moving parts) require upwards of 50 diameters upstream and 20 diameters downstream to operate within the same performance levels as the Siemens SITRANS FM520, MAG 5100W, MAG 3100 and MAG 8000 with zero up and downstream straight runs of piping. $SIEMENS-FM520-Electromagnetic-Flow-Meters-FIG-1 $2$$
A series of tests were conducted through a globally accredited independent approval body, which confirmed that the FM520, MAG 5100W, MAG 3100 and MAG 8000 are capable of exceptional accuracy even in non-standard configurations with an insufficient straight run of pipe.
Based on its demonstrated ability to perform in non-ideal conditions, the FM520, MAG 5100W, MAG 3100 and MAG 8000 can provide 0.6% accuracy in installations with zero diameters upstream and zero diameters downstream straight run pipe from the sensor. The only exception is the presence of a partially opened control valve. In that case, standard straight-run recommendations must be followed.

When you look at which product to select when you don’t have the ideal installation capability, consider the use of Siemens FM520, MAG 5100W, MAG 3100 and MAG 8000 versus the cost of major modifications to your process piping.
