Emerson Launches World’s First PEX Liners for Rosemount Magnetic Flowmeters
Emerson launched world’s first PEX Liners for Magnetic Flowmeters. This is a significant innovation in flow measurement technology with world’s first PEX (Crosslinked Polyethylene) liners for its Rosemount magnetic flowmeter product range.
The new liner option is now available for the Rosemount 8750W Magnetic Flowmeter, Rosemount 8705 Flanged Magnetic Flowmeter, and Rosemount MS Magnetic Flowmeter sensors.
These flowmeters are widely used in water treatment, wastewater processing, slurry handling, and other abrasive industrial applications.
According to Emerson, the new PEX liner technology offers a more durable, environmentally friendly, and cost-effective alternative to traditional liner materials currently used in magnetic flowmeters.
Why Flowmeter Liners Matter
In magnetic flowmeters, the liner protects the sensor body from the process fluid and plays an important role in ensuring measurement reliability and equipment life.
Many existing liner materials face challenges such as:
1. Poor Resistance to Abrasion
Applications involving slurry, wastewater, and fluids containing solids can gradually wear down conventional liners.
2. Chemical Attack
Aggressive chemicals can damage liner materials over time, reducing flowmeter life.
3. Higher Costs
Some traditional liner materials can be expensive to purchase, replace, and maintain.
4. Inventory Challenges
Different applications often require different liner materials, increasing stocking requirements for end users.
These challenges have led many operators to seek more reliable and economical solutions.
Emerson’s New PEX Liner Solution
To overcome these limitations, Emerson has developed a new PEX liner that is exclusively available for Rosemount magnetic flowmeters.
PEX, or Crosslinked Polyethylene, is designed to provide enhanced durability while simplifying material selection and reducing operating costs.
The company states that this new option enables customers to improve reliability without changing their existing flow measurement technology or switching suppliers.
PFAS-Free Design Supports Environmental Goals
One of the most notable features of the new liner is that it is manufactured without PFAS (Per- and Polyfluoroalkyl Substances).
PFAS chemicals have received increasing attention worldwide due to environmental and health concerns. Governments and regulatory bodies are introducing stricter requirements regarding their use and disposal.
By offering a PFAS-free liner, Emerson helps customers address growing regulatory, environmental, and sustainability expectations while maintaining high performance.
This also simplifies material selection compared to fluoropolymer-based liners, which may vary depending on the application.
Improved Resistance to Abrasion
The new PEX liner features a crosslinked molecular structure that provides excellent wear resistance.
This makes it particularly suitable for applications involving:
1. Wastewater Treatment
2. Sludge Handling
3. Mining Slurries
4. Industrial Slurry Applications
5. Fluids Containing Abrasive Solids
In these applications, liner wear is often one of the main factors affecting flowmeter service life. Improved abrasion resistance can help extend equipment life and reduce maintenance requirements.
Lower Cost of Ownership
Another advantage highlighted by Emerson is cost savings.
Despite offering improved durability and environmental benefits, PEX liners are generally less expensive than many traditional liner materials.
This can help end users reduce:
1. Initial equipment costs
2. Replacement expenses
3. Inventory costs
4. Maintenance costs
For facilities operating large numbers of magnetic flowmeters, these savings can be significant over the life of the equipment.
Simplified Inventory Management
Traditional magnetic flowmeter installations often require different liner materials for different process conditions.
This can create inventory challenges and increase spare parts requirements.
The new PEX liner is designed to cover a broader range of applications, helping facilities reduce the number of liner types they need to stock.
This simplifies maintenance planning and spare parts management while lowering inventory costs.
Availability
Emerson has confirmed that PEX liners are currently available for magnetic flowmeters with line sizes up to 8 inches.
The company is also developing PEX liner options for larger line sizes, which will further expand the technology’s application range in the future.
What This Means for the Industry
The launch of the world’s first PEX liners represents an important advancement in magnetic flowmeter technology.
As industries continue to focus on sustainability, cost reduction, and operational reliability, innovations such as PFAS-free liner materials can help operators meet environmental goals while improving equipment performance.
For water and wastewater plants, mining operations, and slurry handling applications, Emerson’s new PEX liner technology could offer a practical solution to some of the most common challenges associated with magnetic flowmeter maintenance and durability.
Final Words
With the introduction of PEX liners for Rosemount magnetic flowmeters, Emerson has delivered a unique solution that combines environmental responsibility, improved abrasion resistance, simplified inventory management, and lower lifecycle costs.
The innovation is expected to benefit a wide range of industries where reliable flow measurement is critical, particularly in water, wastewater, and abrasive slurry applications. As larger sizes become available, adoption of this new technology is likely to grow across the global process industry.
