Endress+Hauser Promag 50W Electromagnetic Flowmeter

The Endress+Hauser Promag 50W Electromagnetic Flowmeter is specifically designed and certified for potable water applications, making it the preferred flow measurement solution for Saudi Arabia's SWCC, NWC, and municipal water utilities. Carrying WRAS (Water Regulations Advisory Scheme), KTW, and ACS drinking water approvals accepted by Saudi authorities for potable water contact materials, the Promag 50W uses NSF 61-certified liners and electrodes that comply with Saudi Arabia's drinking water safety standards administered by the Saudi Food and Drug Authority (SFDA). The transmitter achieves ±0.5% accuracy for NWC billing metering and ±0.3% for high-accuracy SWCC production accounting.

The Promag 50W's empty pipe detection capability uses the electrical conductivity difference between the pipe liner and water to automatically detect empty pipe conditions — preventing false flow registration during NWC network valve operations and SWCC plant startup sequences. The transmitter's HBSI (High-amplitude Background Signal Immunity) algorithm filters out electromagnetic interference from Saudi Arabia's high-voltage SEC power lines that run parallel to water transmission mains, ensuring measurement stability at NWC trunk mains in Saudi urban corridors. Forward and reverse flow measurement serves as quality check for NWC network leakage programs and SWCC transfer pump performance verification.

For NEOM's smart water infrastructure, the Promag 50W's Modbus TCP and HART Ethernet (EtherNet/IP) options connect to industrial IoT platforms without field buses, enabling direct cloud connectivity for NEOM's centralized utility management system. The transmitter's Heartbeat Technology performs automated calibration verification without removing the meter, providing the digital audit trail required by NEOM's water authority for smart meter certification. The multi-electrode system detects partial pipe filling conditions in gravity-drained Saudi Aramco fire water mains and SWCC product water transfer lines.

Razz Middle East is the authorized Endress+Hauser partner for Saudi water authorities, providing complete Promag 50W systems with Saudi authority-accepted calibration certificates, end-to-end installation packages, and drinking water material conformance documentation required for tender submission to NWC and SWCC procurement processes.
