Product Description

The Endress+Hauser 5P5B, part of the Proline Promag P 500 series, is a high-performance electromagnetic flow meter engineered for precise, reliable flow measurement of conductive liquids in the most demanding industrial environments. Leveraging advanced electromagnetic induction technology based on Faraday’s Law, this meter delivers exceptional accuracy, durability, and versatility, making it the preferred choice for process industries worldwide.

1. Core Measurement Technology & Performance

At the heart of the 5P5B is its state-of-the-art electromagnetic induction principle, which ensures measurement accuracy independent of fluid properties such as density, viscosity, pressure, or temperature—eliminating common sources of error in traditional flow meters. This technology enables the 5P5B to deliver consistent, precise readings even in unstable process conditions.
  • Accuracy Class: Up to ±0.2% of the measured value (for DN25-DN2000), ensuring high-precision flow monitoring for critical process control. For smaller diameters (DN15), the accuracy remains excellent at ±0.5% of the measured value.
  • Flow Velocity Range: 0.01 m/s to 12 m/s (0.033 ft/s to 39.37 ft/s), covering both low-flow and high-flow scenarios, from gentle fluid transfer to high-volume industrial processes.
  • Bi-directional Measurement: Supports both forward and reverse flow detection, making it suitable for complex pipeline systems where fluid direction may vary, such as recycling processes or batch operations.
  • Empty Pipe Detection: Integrated empty pipe detection function automatically identifies when the pipe is not fully filled, preventing incorrect readings and ensuring process safety.

2. Rugged Construction & Material Options

The 5P5B is built to withstand harsh industrial conditions, with a robust design that minimizes maintenance and maximizes service life. Its construction materials are carefully selected to resist corrosion, abrasion, and extreme temperatures, ensuring compatibility with a wide range of conductive media.
  • Liner Materials: Optional PTFE (Polytetrafluoroethylene), PFA (Perfluoroalkoxy alkane), or hard rubber liners. PTFE and PFA offer exceptional chemical resistance, making them ideal for corrosive media such as acids, alkalis, and aggressive chemicals. Rubber liners are suitable for abrasive fluids like slurries or wastewater.
  • Electrode Materials: Multiple options available to match specific media requirements, including 316L stainless steel (for general-purpose applications), Hastelloy C (for strong acids and corrosive chemicals), and Tantalum (for highly aggressive media such as hydrofluoric acid).
  • Process Temperature Range: Operates reliably in media temperatures from -20°C to +180°C (-4°F to 356°F), adapting to both low-temperature and high-temperature industrial processes.
  • Protection Class: IP67 or IP68, ensuring dust-tight and water-tight performance, even in outdoor or wet industrial environments. IP68 protection allows for temporary submersion, making it suitable for harsh outdoor installations.

Pressure Transmitter FAQ

What is a pressure transmitter used for?

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.

How do I choose the right pressure transmitter?

Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.

What is the difference between gauge, absolute and differential pressure transmitters?

Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.

Can Xinyi Instrument provide customized pressure transmitters?

Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
