Seametrics MJN Series Multi Jet Meter

Seametrics MJN Series Multi Jet Meter

The Seametrics MJN-Series is an NSF/ANSI 61 certified brass multi-jet meter that provides accurate flow measurement in various water qualities, offering field-adjustable pulse outputs through powered Hall-effect sensors (MJNE), non-powered reed switches (MJNR), or a basic mechanical totalizer (MJNT).

Description

Seametrics MJN Series Multi Jet Meter is a versatile line of multi-jet flow meters certified to NSF/ANSI standard 61 and specifically engineered for simplicity and accuracy in low-quality water conditions. Featuring a durable brass body available in sizes from 3/4” to 2”, these meters utilize a gear-driven mechanical totalizer that allows for easy, tool-free field adjustments to the pulse rate. The series offers three specialized configurations to meet diverse operational needs: the MJNE model uses a powered solid-state Hall-effect sensor for use with external controls, the MJNR utilizes a non-powered two-wire reed switch for dry contact closures, and the MJNT serves as a standalone mechanical totalizer without electronic sensors.
