E&H DMA electromagnetic flowmeter

The Complete Technical Guide to the E&H DMA Electromagnetic Flowmeter: Compact Multi-Variable Measurement for Utilities

In the demanding fields of water treatment, industrial utilities, and OEM skid building, precision, simplicity, and space efficiency are essential. The E&H DMA electromagnetic flowmeter, part of the Endress+Hauser Picomag series, stands as the compact, cost-effective solution for volumetric flow measurement in conductive liquids -6. Engineered to handle the toughest utility applications—from industrial cooling water to rinsing lines—the DMA series delivers reliable performance with an ultra-compact all-in-one design and advanced multi-variable measurement capabilities -3-5.

As a trusted supplier, ST-YUKE CO., LIMITED offers a comprehensive range of the E&H DMA electromagnetic flowmeter configurations. Whether you require a compact DN15 unit for dosing lines or a larger DN50 installation for main utility flows, understanding the technical nuances of this device is crucial for optimal process integration. This guide provides an in-depth look at the technical parameters, model breakdown, and ordering code for the versatile E&H DMA series.

Key Technical Specifications of the E&H DMA Series

The E&H DMA electromagnetic flowmeter is engineered for bidirectional measurement of liquids with a minimum conductivity of ≥10 μS/cm -3. Its operation is virtually independent of pressure, density, temperature, and viscosity, making it exceptionally stable for utility applications. A key differentiator of the DMA series is its ability to simultaneously measure flow, temperature, and conductivity—all in one compact device -3-6.
