Description

The Electronet ELMAG-200W is a next-generation zero-run electromagnetic flow meter engineered for accurate and maintenance-free flow measurement without the need for upstream or downstream straight pipe runs.

Utilizing Faraday’s Law of Electromagnetic Induction, the ELMAG-200W delivers high accuracy, exceptional turndown capability, and stable operation even in challenging water and wastewater applications.

Its full-bore construction ensures zero pressure loss, while the absence of moving parts minimizes maintenance requirements.
Equipped with a robust selection of liners and electrodes, along with an integrated local display, it offers one of the most user-friendly and efficient flow measurement solutions available—without requiring external software or hardware.

Typical applications include:

• Water distribution

• Wastewater treatment

• Industrial utility monitoring

• Irrigation and municipal systems
