Multi Jet MJ-Series water flow sensor | Flow Meter Turbine
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.
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).

Note:
- *-E meters use a solid-state, long-lasting Hall-effect sensor, which
requires power. It is suited for use with Seametrics controls and
metering pumps that have sensor power.
- **-R meters use a two-wire reed switch. They provide dry contact closure and do not require power.
- ***-T meters totalize only and do not have a sensor
- Meter names that include “H” are hot water models (MJH). Without the “H” = cold water models (MJ)
