Specification Sheet

Water meter with pulse output, NSF61 certified for cold water meter

Conforms to AWWA C708

Couplings Included

The pulse emitter device consists of a plastic housing with Reed

Switch and 1.5 m cable with 2 cores in red and black

Horizontal Inline mount with dial facing upward. Suitable for

residential water metering, for metering the water consumption in

your apartments, your irrigation water (which can save you in sewer

costs in some areas). Also suitable for smart building, universities

and commercial

Description

The MJ series of lead free, NSF61 certified, Multi-jet water meters include a pulse output that can be connected to a data collection device for

remote auto meter reading. They are available in sizes from 1/2” up to 2”, in cold water version. They are ready for use with the AMR module

or AMR100/AMR130 display module which are also available from DAE; these modules collect the data from the water meters and sends it

to a remote host for auto meter reading through their RS485 communication interface using the Modbus protocol.

Cold water meters certified by NSF to meet ANSI/NSF 61 for

material safety and ANSI/NSF 372 for lead free plumbing as

defined by California, Vermont, Maryland, Louisiana state laws

and the US Safe Drinking Water Act

Ready for use with DAE AMR130 (Auto Meter Reading Module

for single water meter) and AMR (Auto Meter Reading Module for

16 water meters) for remote reading

AMR or AMR130 will collect data from water meters and send

them to remote host through Modbus/RTU over RS485 with DAE

software EnergyLink400 or third party software

Only two wire connection between water meter and AMR or

AMR130. It is not required for additional power source

System Architecture

Communication

Converter

Modbus/RTU over RS485

The pulse signal cable from the water meter to the AMR may be extended

up to 328 feet (100 meters)

It is recommended that the pulse signal cable make use of AWM 2464

24AWG shielded twisted pair signal cable

The water meter pulse output lead wire is 5 feet (1.5 meters)
