Mechanical Flow Meter MJ Series - Seametrics

The Seametrics MJ-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. Seametrics offers cold or hot water models.

Seametrics Mechanical Flow Meter MJ

Designed for metering pump pacing or water treatment control

Hot or cold water models

Rugged epoxy-coated bronze bodies with union ends

Mechanical register

Reed switch (MJR) or Hall-effect (MJE) output

100:1 turndown

Wide range of field-changeable pulse rates

True dry-top construction

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 feld.
Mechanically, all MJ-Series meters are the same. The difference among *MJE/MJHE, *MJR/MJHR and *MJT/MJHT meters is in the sensor. MJE/MJHE 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. MJR/MJHR meters use a two-wire reed switch. They provide a dry contact closure and do not require power. MJT/MJHT meters totalize only and
do not have a sensor.
*Note on Nomenclature: Meter names that include “H” are hot water
models. Without the “H” = cold water models.
