Endress+Hauser Promag P 500 DN80 Electromagnetic Flowmeter

Overview

The Endress+Hauser Proline Promag P 500 DN80 flowmeter (order code 5P5B80, DN80 / 3-inch nominal size) is a general-purpose electromagnetic flowmeter engineered for reliable, maintenance-free liquid flow measurement across chemical, process and utility applications. As a full-bore magmeter, it has no moving parts and no obstruction in the flow path, so measurement accuracy is unaffected by changes in pressure, density, viscosity or temperature of the process fluid.

The Promag P 500 pairs a robust process-grade sensor with Endress+Hauser’s advanced Proline 500 transmitter platform, giving plant engineers a device that combines rugged field reliability with smart diagnostics for compliance and predictive maintenance. Seven Star LLC supplies the genuine Promag P 500 DN80 flowmeter to industrial and process customers across Muscat, Sohar, Salalah and the wider GCC, backed by manufacturer documentation and technical support for sizing, wetted-material selection and commissioning.

Measurement Principle

The Promag P 500 DN80 flowmeter works on Faraday’s law of electromagnetic induction. Coils in the sensor generate a magnetic field across the measuring tube; when a conductive liquid flows through this field, a voltage is induced that is proportional to the flow velocity. Two measuring electrodes in contact with the liquid pick up this voltage, and the transmitter converts it into volume flow using the known internal diameter of the DN80 tube.

Because the measurement relies only on the fluid’s velocity and conductivity, the reading is essentially independent of pressure, temperature, density and viscosity, and the open, unobstructed bore causes no additional pressure loss. The practical consequences are important for process plants: nothing wears out in the flow path, there is no risk of blockage from solids, and long-term stability is high. The main condition is that the liquid must be electrically conductive, which is the case for water, wastewater, acids, alkalis and most aqueous process liquids.

Engineering Design of the Promag P 500 DN80 Flowmeter

The Promag P sensor is designed for chemical and process applications, with a choice of liner and electrode materials to suit corrosive or high-temperature media. Liner options include PFA, high-temperature PFA and PTFE, and electrodes are available in 316L stainless steel, Alloy C22, tantalum, titanium, platinum and duplex steel. Depending on liner selection, the process temperature range extends from −40°C to +180°C, and pressure ratings reach up to PN 40 / Class 300 depending on configuration.

The Proline 500 transmitter is mounted separately from the sensor, which lets the electronics and display be installed in an accessible, protected location while the sensor sits in the pipe. The transmitter offers a backlit touch-control local display and a wide choice of communication protocols, and it supports 0×DN mounting, meaning accurate readings can be achieved even immediately after bends or other fittings — a real advantage on crowded skids and in retrofit projects where straight pipe runs are limited.

Key Features

The Promag P 500 DN80 flowmeter offers the following key features:

• Maintenance-free operation with no moving parts in the measuring tube.
• Accuracy of ±0.5% of reading (standard) or ±0.2% with the Flat Spec option, largely independent of process pressure and viscosity.
• Wide flow range from 4 dm³/min up to 9,600 m³/h across the Promag P 500 size range, with DN80 sized for typical process-line flow rates.
• Pressure rating up to PN 40 / Class 300 depending on configuration.
• Liner and electrode material options (PFA, PTFE liners; 316L stainless steel, Alloy C22, tantalum, titanium, platinum and duplex-steel electrodes) for compatibility with corrosive and demanding process media.
• Temperature range from −40°C to +180°C depending on liner selection.
• Heartbeat Technology diagnostics for in-situ verification, self-monitoring and documented compliance without process interruption.
• Multi-protocol connectivity: HART, PROFIBUS DP/PA, FOUNDATION Fieldbus, Modbus RS485/TCP, PROFINET, EtherNet/IP and OPC-UA, with a backlit touch-control local display.

Industrial Applications

The Promag P 500 DN80 flowmeter is suited to process industries where a robust, general-purpose magmeter is needed for conductive liquids: chemical processing and electrolysis lines, water and wastewater treatment, corrosive liquid transfer, and general utility flow monitoring in oil, gas and power-generation support systems. In Oman, typical installations include chemical dosing and neutralization lines, produced-water and effluent treatment, RO desalination pre-treatment and brine lines, and cooling-water systems in the Sohar and Salalah industrial zones.

Seven Star LLC supplies genuine Endress+Hauser Proline Promag P 500 flowmeters to industrial and process customers throughout the Sultanate of Oman and the GCC. Choosing the correct DN size and liner/electrode combination for the process fluid is critical to long-term accuracy and reliability, so our team helps confirm the right configuration — including the order code — for each application before purchase. Heartbeat Technology verification is particularly valuable for plants that must document meter performance for audits without removing the Promag P 500 DN80 flowmeter from the line.
