The world’s first magmeter to measure flow independently of flow profile and mounting location

In the water and wastewater industry, high measurement accuracy is indispensable for optimal process control. A variety of influences, such as a close-knit pipeline network or obstacles in the pipe, cause flow turbulences that affect accuracy. Promag W from Endress+Hauser features the “0 x DN full bore” option, a solution for this challenge that is the only one of its kind in the world: maximum measuring performance without tube restriction and thus without pressure loss.

Benefits

• Best measuring performance independent of flow profiles
• The first and only electromagnetic flowmeter with no inlet and outlet runs (0 x DN), no measuring tube restriction (full bore) and thus no pressure loss
• Perfect solution for installation in space-restricted situations, e.g. on skids; especially after fittings and other turbulence-generating obstacles in the pipe

Promag W 300/400/500 flowmeters with the “0 x DN full bore” option measure with high accuracy (±0.5%). They are particularly suitable for installation in tight spaces, e.g. on skids, as they do not need any inlet or outlet runs. Thus, Promag W can easily handle frequently occurring swirl downstream of obstacles such as pipe bends, insertion devices, build-up on the pipe wall, protruding seals or different inside diameters. Thanks to the design without restriction, there is no pressure loss.

Long-lasting battery-powered magmeter with secure system integration and communication

The Endress+Hauser Promag W 800 is ideal for off-grid applications in the water industry, including flow measurement in direct underground installation or underwater. The battery-powered transmitter provides worldwide transmission of measured data without any additional power supply. Built-in Heartbeat Technology ensures measurement reliability and compliant verification.

• Bidirectional measuring principle is virtually independent of pressure, density, temperature and viscosity
• Accurate measurement with 0 x DN inlet run
• Dedicated to the measurement of industrial or municipal water and wastewater
• International drinking water approvals
• Degree of protection IP68 (Type 6P enclosure)
• Transmitter housing made of durable polycarbonate
• Battery lifetime up to 15 years
