SeaMetrics, MJNR-200, NSF Bronze Body Pulse Meter, Cold-Water, 2"
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).
MJNR meters use a two-wire reed switch. They provide a dry contact closure and do not require power.
Features:
- Certified to NSF/ANSI standard 61
- Dry top multi-jet design
