Differential pressure (DP) flowmeters are the most common type of flow measurement products in use today. ABB offers a wide range of flowmeters and primary elements to suit almost all applications. Meters available include compact and integral orifice flowmeters, averaging pitot tubes, venturi tubes, wedge meters, sub-sea meters, orifice plates, orifice carrier assemblies, flow nozzles and wet gas meters. All are available with full certification of materials, welding and NDE. ABB also supplies compact DP flowmeters built to optimize and sustain overall performance and reliability by the integration of multiple components into a single easy to install flowmeter package. ABB offers the most comprehensive DP flowmeter portfolio in the market, including improved measurement performance that can be easily customized for any application.
More than 100 years of experience in the supply of DP Flow Products and Solutions
- Full range of primary elements with low net pressure loss that enable reduced energy costs and a smaller carbon footprint
- Robust and reliable solutions for difficult applications in areas where previous flow measurement was unattainable
- Comprehensive line of compact DP flowmeters that deliver real-time measurement with a single pipe penetration. This reduces overall installation costs, offering simple installation by eliminating the need for impulse lines, special flanges or pipe modifications
