Introduction

Stealth Reader networks are used for remote monitoring of commercial, industrial, and municipal equipment such as automatic utility metering. Hundreds of thousands of devices are currently being monitored by Stealth Reader networks.

The Stealth Reader MIU is the next-generation of MeshPlus water MIUs. The Stealth Reader extends the feature set of the MeshPlus WM1 and is fully compatible with MeshPlus WM1 products. The Stealth Reader offers WM1 backward compatibility with extended wireless range and extended battery life. The Stealth Reader is based on the proven WM1 design with over 500,000 MlUs deployed; added features include increased reliability, and improved wireless performance.

Quick Tour

The Stealth Reader is powered by two replaceable lithium-thiony| chloride (LiSOCI2) batteries. The Stealth Reader electronics are permanently encased in a urethane potting compound to protect them from water and chemicals. The end cap is secured by a single screw to secure the batteries, electronics and cabling. The Stealth Reader interface cable includes 8 colored wires for connecting to a wide variety of water meter registers. Stealth Readers can also be ordered with a 3-wire Nicor cable for encoders wired with Nicor cables. The Stealth Reader enclosure supports mounting in a variety of environments including pole, wall, and pit mounts.

Pre-Installation

Supplies/Equipment

In order to install the Stealth Reader properly the following Equipment is needed:

The Stealth Reader

Wire-end Connectors

Lid Lock (for pit mounting) or Wall/Pole mount
Stealth Handheld

In order to install the Stealth Reader and prevent water damage these materials are needed:

UY Gel Cap Connectors
3ME9-Y Crimping tool
Burial Pod (pit installs, not necessary for indoor installs)

Installation

This section covers the installation of the Stealth Reader and the mounting process.

Considerations

Signal distance depends on the location of the Stealth Reader’s antenna. When the Stealth Reader’s antenna is higher the signal is generally stronger. The use of a Riser plate will increase the height.
Different materials used for the Pit Lid or Vault will affect the transmission range. A plastic lid allows a longer range compared to a cast iron lid.
The installation usually takes 10 minutes if the meter pit lid can accept the Lid Lock Assembly, but it will depend on the location and mounting. Make sure there is enough space between the box lid and the ground for the Stealth Reader to fit. If there isn’t enough space for the Stealth Reader to fit properly, remove some dirt from the area. Do not over-tighten lid locks!

Procedure

Connecting to the Register

The Stealth Reader is wired directly to the meter. The following table matches the type of Register and the wires that need to be connected for each type. Follow the instructions in the Connection Techniques Section at the end of the chart. If the wiring is not per the chart, the Stealth Reader will not work properly with the meter. Some
Registers will have screw terminals. The screws will be labeled with either the word or the starting letter of the colors, for example “R, G, B, etc.”.

Connection Techniques

When connecting he Stealth Reader to the Register please use the following procedure:
1. Check the chart above for the proper wiring for the brand and model of register.
2. Connect the wires using UY gel cap connectors. If the wires are stripped, cut of the stripped ends. Wires must have un strapped ends in order to use the gel cap connectors. Use the Gel Cap Crimping tool to Secure the gel cap connectors.
3, The connections for encoded registers will be tested during Stealth Reader installation, however pulse register connections cannot be tested so is important to be sure the wires are connected correctly before
inserting in the burial pods.

If the wires are installed incorrectly and need to be repaired, use the following steps:
1. Cutoff the wires where they enter the UY gel caps.
2. Repeat procedures 2-3 from the section above.

There are some registers that use screw terminals instead of wires; each screw terminal has a letter next to it indicating the equivalent wire color it represents. Use the model and brand of register to find the proper wiring in the chart above then follow these installation stops:

1. Examine the wiring chart above to identify the proper wire to screw- terminal connections.
2. Wrap the connect wire around the screw terminal dock wise.
3. Tighten the screw while also making sure the wire stays in place. In doing this i the wires are wrapped around the correct way, it will tighten itself when the screw is being tightened.
4. Repeat steps 2 and 3 for each screw terminal

Splicing Techniques

This method ensures wire connections are completly water prof.

Water Pit Splice Method using burial pods

Make sure that the gel caps are completely in the grease.
Seal the burial pod

Water Pit Splice Method for Direct Register Connections

Strip the outer cable shield back 4 inches.

Strip the insulation from the used wires % of an inch.
Cut off excess wire and direct connect to the water register according to the wire connections chart per register type.

Mounting

The Stealth Reader supports several mounting options including pt, wall, and pole mounting.

Pit Mounting
1. Gather the mounting materials as shown in the picture below.

tools

2. If the Riser (9) is used, place the Screw Top (1) through the Riser from the indented side of the Riser. Place the Screw Top through the hole in the pit id. If there is no Riser, place the Screw “op directly through the hole in the pit id. The threaded portion of the Screw Top should be pointing down (into the pi).
3. Use the Nut (2) o secure the Screw top onto the Pit Lid. Tighten the Nut until it can’t be tightened further, but do not over-tighten it.
4. install the Stealth Reader top (opposite the wire) and place it Screw top. Tum the Stealth Reader nti a dick is hear, the click indicates that the Stealth Reader is locked into the Screw Top.
5. Carefully cover the pit with the pit id (that now has the Stealth Reader attached) and make sure the lid doses completely without putting weight on the Stealth Reader. Never it the weight of the Lid be supported by the Stealth Reader or the Stealth Reader or wiring can be damaged.
6. Pick up all trash in and around the pit.
7. Secure the Lid.

Proper/ Improper Pit Mounting

With Pit Mounting, the Stealth Reader should be upright and the lid should be able to close and seal securely. The picture to the right shows an INCORRECT installation of a Stealth Reader. The Reader is sitting to high and the lid can’t close properly. To fix this problem remove dirt from beneath the reader until the lid can close properly without putting any weight on the Stealth Reader. If a Stealth Reader has been improperly installed, it should be checked
for damage and proper operation before being retuned to service;
if the case, mounting hardware, or wiring is damaged, the Stealth
Reader should be replaced.

Configuration

Stealth Reader installations are performed using a Stealth Handheld. The Stealth Handheld guides installers through the installation process, records the details of each installation, and tests and configures installed Stealth Readers.

Stealth Handheld may be used as stand-alone tools allowing Stealth Readers to be installed as needed (e.g. for demonstration purposes or to serve as repeaters). Stealth Handhelds are also fully integrated with the Stealth Reader Web work order management system allowing installations to be planned and assigned to installers or install teams.

Whether performing as-needed installations or work-order assigned installations, the process is similar and is described in the SR Handheld Users Guide.

LED Behavior

When the Stealth Reader is activated, two LED indicators provide visual status information. With a few exceptions, the Red LED generally provides status information regarding the connection between the Stealth Reader and the water register; the Green LED provides status information regarding the communication link between the Stealth Reader and the Fixed Wireless Network.

The following chart identifies the status information a Stealth Reader may provide:
