…Introduction
WaterMaster – always the first choice
WaterMaster sets the standard for the water industry. The
specification, features and user benefits offered by this range
are based on ABB's worldwide experience in this industry and
they are all targeted specifically to the industry's
requirements.
Submersible and buriable
WaterMaster sensors have a rugged, robust construction to
ensure a long, maintenance-free life under the arduous
conditions experienced in the Water and Waste Industry. The
sensors are, as standard, inherently submersible (IP68, NEMA
6P), thus ensuring suitability for installation in chambers and
metering pits that are susceptible to flooding.
A unique feature of the WaterMaster sensors is that sizes
DN40 to DN2400 (1½ to 96 in. NB) are buriable; installation
simply involves excavating to the underground pipe, fitting
the sensor, cabling back to the transmitter and then
backfilling the hole.
