Endress+Hauser Promag 50P Electromagnetic Flowmeter
Overview
The Endress+Hauser Promag 50P is an electromagnetic flowmeter dedicated to chemical and process applications involving corrosive liquids and high medium temperatures. Paired with the proven Promag 50 transmitter, it delivers highly accurate liquid flow measurement across a wide variety of wetted materials, with no moving parts to wear and no pressure loss from cross-section constriction.
As the official authorized partner and exclusive regional representative for Endress+Hauser, Seven Star LLC proudly supplies the Endress+Hauser Promag 50P to chemical plants and process industries across the Sultanate of Oman and the wider GCC, backed by genuine factory calibration, full documentation, and local technical support.
Measurement Principle
The Endress+Hauser Promag 50P operates on Faraday’s law of electromagnetic induction. As a conductive fluid flows through the magnetic field generated across the measuring tube, it induces a voltage proportional to the fluid’s velocity; this signal is picked up by a pair of measuring electrodes in contact with the process fluid and processed into a volumetric flow rate.
Because the measurement depends only on fluid conductivity and velocity, it is unaffected by changes in density, viscosity, temperature, or pressure. The full-bore PTFE- or PFA-lined measuring tube presents no obstruction to the flow path, resulting in zero pressure loss, no moving parts to maintain, and stable long-term accuracy even in corrosive or high-temperature chemical service.
Engineering Design of the Endress+Hauser Promag 50P
The sensor is available in nominal diameters from DN 15 to DN 600 (1/2 inch to 24 inch), with a liner made of PTFE or PFA selected to suit corrosive media and high medium temperatures up to 180°C. The sensor housing achieves IP67 (NEMA 4X) as standard, with an IP68 (NEMA 6P) option for submerged or heavily washed-down installations, and all common Ex approvals are available for hazardous-area duty.
The Promag 50 transmitter features a two-line backlit display with push-button operation for local configuration and diagnostics, and is available in compact or remote versions to suit installations where vibration, heat, or access constraints make a sensor-mounted transmitter impractical.
Key Features
The Endress+Hauser Promag 50P is engineered for demanding chemical and process duty, and the Endress+Hauser Promag 50P remains a dependable choice wherever corrosive liquids and high temperatures rule out mechanical meters:
- Delivers measurement accuracy of ±0.5% standard, improving to ±0.2% with the calibration option.
- Covers nominal diameters from DN 15 to DN 600 (1/2 inch to 24 inch) for a wide range of line sizes.
- Handles medium temperatures up to +180°C, suited to demanding chemical process duty.
- Uses a PTFE- or PFA-lined measuring tube for compatibility with corrosive and aggressive liquids.
- Introduces zero pressure loss thanks to its full-bore, obstruction-free flow path.
- Has no moving parts, eliminating wear-related maintenance and reducing lifecycle cost.
- Achieves IP67 (NEMA 4X) protection as standard, with IP68 (NEMA 6P) available for wash-down duty.
- Is available in compact or remote transmitter versions to suit installation and access constraints.
Industrial Applications
The Endress+Hauser Promag 50P is specified across chemical processing plants, corrosive effluent lines, and process units handling aggressive or high-temperature liquids where PTFE- or PFA-lined construction is essential to instrument survival. Its conductivity-based measurement principle also suits water and wastewater treatment, dosing and blending, and general industrial process lines where reliable, maintenance-free flow data is required.
As the officially authorized partner for Endress+Hauser, Seven Star LLC distributes the Promag 50P to chemical and process facilities throughout Oman and the GCC, including projects in the Sohar and Salalah economic zones, water treatment and desalination plants, and petrochemical complexes, supported by regional stock availability and factory-trained technical staff.

Why Choose Seven Star LLC for Endress+Hauser Chemical-Duty Electromagnetic Flowmeters
Choosing between a PTFE and PFA liner is not a minor detail on corrosive chemical service — the wrong choice can shorten instrument life dramatically at elevated medium temperature, and getting the IP rating wrong on a wash-down or submerged installation creates a real ingress risk. Seven Star LLC verifies liner material, temperature rating, and enclosure protection against your actual chemical process conditions before the Promag 50P ships, backed by our authorized Endress+Hauser partnership across Oman and the wider GCC. We also help chemical plants plan compact-versus-remote transmitter configuration around vibration and access constraints on site, and coordinate regional delivery and calibration documentation for process units in Sohar’s industrial zones, including planning ahead for spare electrode and liner assemblies on critical process lines.
