Mechanical Flow Meter MJN Series - Seametrics

The Seametrics MJN-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 Seametrics MJN-Series is NSF-61-G certifed. 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).

NSF-61 Certified to comply with federal regulation

Changing the pulse rate requires no special tools and can be done in the feld.
Mechanically, all MJN-Series meters are the same. The difference among MJNE, MJNR and MJNT meters is in the sensor. MJNE meters use a solid-state, long-lasting Hall-effect sensor, which requires power. It is suited for use with Seametrics controls and metering pumps (LMI for instance) that have sensor power. MJNR meters use a two-wire reed switch. They provide a dry contact
closure and do not require power. MJNT meters totalize only and do not have a sensor
