Product Overview

You’ll find the Assured Automation Brass Water Meter for Home and Garden Use, WM-NLC Series – NSF Certified Water Flow Meter – Lead Free (1” Pulse Output) is built for straightforward, long-term service. It’s a multi-jet dry-type totalizing meter designed to measure household water consumption while resisting the wear that often shortens meter life.

What this product is intended for

You can use this meter to measure potable water usage in residential and light commercial settings, or to monitor irrigation and garden systems. It’s intended to fit standard 1″ connections and can be integrated with building monitoring systems if you choose the pulse output option.

Key Features

You’ll appreciate that the WM-NLC Series combines durability, measurement stability, and the option for electronic output. Below are the main features that will affect installation, maintenance, and long-term performance.

Corrosion Resistant Construction

All parts that contact water are made from corrosion-resistant materials, which protects internal geometry and accuracy over time. That means fewer surprises when you open the meter for a check or if the water quality isn’t ideal.

Lead-Free Meter Body

The meter body and coupling use a low-lead brass alloy (C87850), so you’re getting a product that meets potable water safety standards. If you’re installing in a domestic environment or anywhere local codes demand low-lead components, this meter addresses that requirement.

Dry Top Multi-Jet Design

The dry-top multi-jet register keeps the counting mechanism isolated from the water, which improves reliability and readability. The multi-jet impeller design tolerates a wider flow range and can cope with water that has particulate content better than single-jet meters.

Minimal Moving Parts

Only the impeller contacts flowing water, which reduces wear and extends service life. Fewer wet moving parts typically translates to more stable long-term accuracy and less frequent replacements.

Removable Inlet Filter

There’s a removable filter at the inlet that you can clean without opening the entire meter, so routine maintenance is less invasive. That filter protects the impeller and internal passages from debris that could impair accuracy.

Optional Pulse Output

If you need remote monitoring, the meter offers an optional pulse output: a plastic housing with a 2-wire reed switch (red and black) and cable. You can connect it to a building automation system, data logger, or a simple pulse counter depending on your monitoring needs.

Installation Guide

You’ll want to prepare your installation site and tools before you start. Proper positioning, correct orientation, and a few simple checks during plumbing work will save you time and prevent leaks or inaccurate readings.

Pre-installation checklist

Make sure you have the correct 1″ pipe fittings, PTFE tape or thread sealant rated for potable water, and a way to isolate the water line. You should also confirm the direction of flow and ensure there’s space for reading the register and accessing the hinged lens cover.

Orientation and piping considerations

Install the meter in a horizontal run unless the manufacturer allows otherwise; meters often expect horizontal mounting with the register facing upward. Avoid long vertical runs directly upstream or downstream of the meter and install short sections of straight pipe before and after the meter to stabilize flow when possible.

Connecting the Pulse Output

If you use the optional pulse output, route the reed switch cable to your data collection point and maintain a neat, secure run free from sharp bends and mechanical stress. Keep in mind the reed switch is typically low-voltage and should be connected to compatible pulse counters or data loggers per their wiring diagrams.

Water pressure and temperature checks

You should check the local supply pressure and temperature to ensure they fall within the meter’s allowable range. Excessive pressure transients or temperatures outside specification can damage the meter or cause measurement errors.

Performance & Accuracy

You’ll be interested in how accurate and stable this meter is over time. The WM-NLC Series aims to balance cost and performance for household and garden applications.

Measurement stability

The dry-top register design helps preserve accurate readings because the register doesn’t sit in the water stream. You’ll find the meter performs consistently across its rated flow range, giving you dependable billing or consumption data.

Flow range and reliability

Multi-jet meters generally handle low-to-moderate flow rates well and hold accuracy across a wide range, which is beneficial for intermittent household use and irrigation cycles. If you have frequent high-flow events, it’s worth comparing the meter’s maximum flow rating to your peak demands.

Factors that affect accuracy

You should be aware that entrained air, significant debris, or pulsating flow from pumps can influence readings. Keeping the inlet filter clean and ensuring proper straight-run piping will help maintain accuracy.

Durability & Materials

You’ll benefit from components chosen for longevity and resistance to common water-related deterioration. The materials and design minimize points of failure and resist degradation in typical residential water environments.

Low-lead brass alloy benefits

The C87850 alloy offers a balance of machinability, corrosion resistance, and compliance with potable water standards. Because it’s low-lead, you won’t run afoul of many modern plumbing codes that aim to reduce lead exposure.

Corrosion resistance in wetted parts

Having all wetted parts made from corrosion-resistant materials prevents pitting and material breakdown over the meter’s service life. This reduces the chance that roughened surfaces or leaks will develop in a few years due to water chemistry.

Register protection

The hinged lens cover is a small but valuable feature: it keeps dirt and sunlight off the register and makes reading easier when the meter sits outdoors. A protected display is less likely to be fogged, scratched, or damaged by debris.

Maintenance & Cleaning

You’ll want to know how much time and effort you’ll need to keep the meter working well. Routine inspections and the removable filter make maintenance straightforward.

Routine inspection steps

Check the register and housing for cracks or clouding, inspect the inlet filter for debris, and verify fittings for leaks. Also, periodically read the meter and compare consumption to expected usage to catch anomalies early.

How to clean the removable filter

Turn off the supply, remove the meter or access the filter assembly per instructions, and rinse or brush the filter under running water. Return the filter and check the meter for normal operation; you should see improved flow if the filter was clogged.

When to call a professional

If you detect persistent inaccuracies, physical damage to the meter body, or electrical issues with the pulse output, you should contact a licensed plumber or the meter vendor.
