The Seametrics MJ Series pulse water meter is a contacting head water meter which utilizes the multi-jet
principle, an internationally-accepted standard for many years. Multi-jet flow meters utilize an impeller
which is centered in a ring of jets, with inlet jets on one level and outlet jets on another. This type
of meter is known for its wide range, simplicity, and accuracy in low-quality water.
The Seametrics MJ Series pulse water meter is available in sizes ranging from 3/4 to 2 inch. The
Seametrics MJ Series pulse water meter is available with flow ranges from 0.22 to 132 gpm (depending upon
meter size) with an accuracy of 1-1/2% of reading.
The Seametrics MJ Series pulse water meter is available with a totalizer or pulse outputs. Pulse outputs are
either a solid-state, long-lasting Hall-effect sensor, which requires power or a two-wire reed switch which
provides a dry contact closure and does not require power. Pulse rates are factory-set to customer specifications
but can easily be changed in the field without special tools.
