Install Sensor(s)

Pulse Cable for Dry Contact Pulse Meters

Eyedro Flow Meter for Pulse Output Meters are intended to interface with the following pulse meter output formats:

• Form A (KY) dry contact pulses
• 5V DC wetting value¹
• Rising or falling edge detection (default is rising edge)
• Minimum pulse width is 5ms
• Maximum frequency is 100Hz

¹ A higher wetting value (up to 24V) can be achieved by connecting a separate DC power supply (not provided) to input port C of the Eyedro Pulse Monitor module. The mating connector for port C is a 1.65mm (i.d) x 3.5mm (o.d) x 9mm (length) barrel plug with center pin positive.

1. Connect pulse cable to the output of the pulse meter
   • Black conductor of the pulse cable to the K output of the pulse meter.
   • White conductor of the pulse cable to the Y output of the pulse meter.
2. Optionally, use tape or other label to uniquely identify each sensor at the end of the wire nearest to the connector.
3. Route pulse cable(s) to the Eyedro Pulse Meter.

Sensor Probe for Gas and/or Water Meters

Eyedro Flow Meter for Gas and/or Water Meters are intended to interface with the following meter types:

• Water Meters: positive displacement, compound, single-jet, multi‐jet, piston
• Gas Meters: diaphragm, rotary, and most turbine
• Indoor or outdoor (probe and cable only)
• Submersible probe and cable
• Burial-safe probe and cable

IMPORTANT: Incompatible with solid state meters (ultra-sonic) and horizontal turbine (Sensus Omni and Mach II)

IMPORTANT: Not intended for hazardous locations

1. Place the tip of the sensor probe
   • For diaphragm meters, this is typically on the front surface of the meter under the register.
   • For other meters, this is typically in the area where the meter chamber and register meet.
   • PRO TIP: Use the Physics Toolbox Sensor Suite app (described below) to find the best location to install the sensor probe. Instructions below.
2. Secure the sensor to the meter with the large cable ties provided in the box.
3. Optionally, use tape or other label to uniquely identify each sensor at the end of the wire nearest to the connector.
4. Route cable(s) to the location of the Eyedro electronics (indoors).
   • If necessary, cable can be extended using appropriate CAT6 cable with RJ45 wet/dry coupler(s) as needed. DO NOT exceed a maximum length (probe + extension) of 60m (200ft)

PRO TIP: Assuming your mobile device supports Near Field Communication (NFC), you can use the Physics Toolbox Sensor Suite application on your mobile device to locate the best place to install the sensor.

1. Download the Physics Toolbox Sensor Suite app on your mobile device.
   • Google Play
   • Apple Store
2. Choose Magnetism > Magnetometer option from the app home page.
3. Hold the phone near the NFC spot at various locations around the water or gas meter to find the highest magnetic reading.
   • IMPORTANT: Ensure there is gas/water actively moving through the meter at the time of the installation.

Mount Eyedro Device

Vertical (wall) Mounting

1. Write down the 8-digit serial number from the back of the module. This will be required during software setup.
   • The serial number will be in the format “123 – 45678“
   • PRO TIP: Record the serial number on the Quick Start Guide along with any other installation details.
2. Find a clear area on the wall or surface to mount the device.
   • Make sure all cables will easily reach the module before securing.
3. Mark locations on the wall for the screws using the module as a template.
4. If preferred, drill a pilot hole in the marked locations using a 2.5 mm (7/64″) drill bit.
5. Drive the two (2) pan head screws into the wall surface through the flange holes on the sides of the enclosure.
6. Carefully tighten the screws until snug. Do not overtighten or it may cause damage to the flange(s).
7. Ensure secure fit.

Horizontal (surface) Mounting

Mounting is not required for horizontal installations (i.e., on a desktop or shelf). If added security is desired, follow instructions for vertical mounting using screws or double-sided tape.

Connect Cabling

Important

• Ensure all connectors and sockets are free from damage prior to mating them.
• Ensure the retention clip on the Ethernet cable is intact.
• Never force connectors.
• Never apply levering action while connecting or disconnecting.
• Always grasp connectors by the strain relief while connecting or disconnecting.
• Ensure all connections are secure.

Dry Contact (KY) Pulse Meters

1. Connect the pulse cable(s) to the sensor input ports (A or B) of the Eyedro Pulse Meter.
   • NOTE: The mating connector for the sensors are 1.3mm (i.d.) X 3.5mm (o.d.) X 9mm (length) barrel plug.
2. Optionally, connect the wetting voltage power supply to obtain a wetting voltage greater than 5V DC – not included.
3. For devices that will connect to the internet via Ethernet
   • Connect one end of Ethernet cable to Eyedro module.
   • Connect the other end of the Ethernet cable to the Internet access point.
4. Connect the appropriate end of the low-voltage power adapter to the Eyedro module.
5. Connect the appropriate end of the low-voltage power adapter to the Eyedro module.
   • Pulse monitoring devices use a power supply with a 5V DC output.
6. Plug the other end of the low-voltage power adapter into a nearby AC wall receptacle.
7. Optionally, secure all wiring neatly with tie wraps (not included).

Dry Contact (KY) Pulse Meters Optional – Increased Wetting Value (>5VDC)

1. Connect the appropriate end of the wetting voltage DC power adapter (24V DC max – not included) to port C of the Eyedro Pulse Meter.
   • IMPORTANT: The mating connector for port C is a 1.65mm (i.d) x 3.5mm (o.d) x 9mm (length) barrel plug with center pin positive.
2. Plug the other end of the wetting voltage DC power adapter into a nearby AC wall receptacle.

Gas/Water Pulse Meters

1. Connect the MR Probe to the appropriate jack on the Eyedro Gas and Water Interface Module (MR probe module).
2. Connect the data output cable (black and white cable) from the Interface Module to one of the sensor input ports (A or B) of the Eyedro Pulse Meter (A34 module).
3. Connect the power jumper cable (black cable) from the Interface Module to the power port of the Eyedro Pulse Meter.
4. For devices that will connect to the internet via Ethernet
   • Connect one end of Ethernet cable to Eyedro Pulse Meter.
   • Connect the other end of the Ethernet cable to the Internet access point.
5. Connect the appropriate end of the low-voltage power adapter to the power port of the Eyedro Pulse Meter.
6. Connect the appropriate end of the low-voltage power adapter to the Interface Module.
   • Pulse monitoring devices use a power supply with a 5V DC output.
7. Plug the other end of the low-voltage power adapter into a nearby AC wall receptacle.
8. Optionally, secure all wiring neatly with tie wraps (not included).
