MJ-Series Multi-Jet Seametrics Pulse Meter

MJ-Series

MJ/MJH-Series meters use the multi-jet principle, which has been an internationally-accepted standard for many years. This type of meter is known for its wide range, simplicity, and accuracy in low-quality water. The impeller is centered in a ring of jets, with inlet jets on one level and outlet jets on another. A gear train drives the register totalizer dials. For pulse output, one of the pointers is replaced by a magnet, which is detected by an encapsulated sensor attached to the outside of the lens.
Pulse rate is determined by the dial on which the magnet is placed, and by the number of sensors (single or double).
Changing the pulse rate requires no special tools and can be done in the field. MJE (cold water) and MJHE (hot water) meters use a solidstate, long-lasting Hall-effect sensor, which requires power.
They are suited for use with Seametrics controls and metering pumps (LMI for instance) that have sensor power. MJR (cold water) and MJHR (hot water) meters use a reed switch. They provide a dry contact closure and do not require power. MJT (cold water) and MJHT (hot water) meters do not have a sensor, and they totalize only.
