Data sheet for the ABB WaterMaster DS/WM electromagnetic flowmeter, detailing specifications, features, and performance for water and wastewater applications.
The ABB WaterMaster DS/WM is an electromagnetic flowmeter designed specifically for diverse applications in the water and waste-water industry. It offers a wide range of sizes from 40 to 2200 mm and is built with rugged, robust construction that makes it inherently submersible and suitable for burial underground.
Key features include a unique self-calibrating transmitter technology that ensures ultra-stable performance and high accuracy without the need for factory recalibration. The device complies with OIML R49 Type 'P' requirements and NAMUR NE107 diagnostics, providing comprehensive sensor checking and clear diagnostic indications.
The WaterMaster range is available in sizes ranging from 40 to 2200 mm, which corresponds to 1½ to 84 inches.
The device has an operating flow range with ±0.4 % accuracy as standard, though ±0.2 % is available as an optional specification.
All WaterMaster sensors are inherently submersible with an IP68 rating and a NEMA 6P rating to ensure suitability for flooding conditions.
