HCQ3B6ETIMTIntegrated Water Meter with Transmitter

© 2006 Inovonics Wireless - www.inovonicswireless.comPage 1 EN1550 MetraMeter™ Installation and Operation Manual - 04672A 1 Overview The EN1550 combines the quality of a Neptune® T-10 water meter with the latest Inovonics Wireless EchoStream RF technology to provide an integrated meter transmitter for use in the TapWatch submetering system. 1.1 Inovonics Wireless Contact Information If you have any questions about this product, contact Inovonics Wireless technical services: • E-mail: [email protected] • Phone: (800) 782-2709; (303) 939-9336 1.2 EN1550 Components Figure 1 EN1550 Components 2 Installation and Startup 2.1 Install the Power Pack You must install the power pack for the EN1550 to function. To install the battery pack: 1. Carefully align the three power pack pins to the three holes in the top of the register and press down evenly, keeping the pins perpendicular to the holes. Caution: Install the power pack carefully. If the pins are not kept perpendicular with the register during installation, they may break. Never install the power pack at an angle. Figure 2 Install the Battery Pack 2. Snap the battery pack enclosure into place over the battery pack. Figure 3 Install the Battery Pack Enclosure 2.2 Install the Meter To install the meter: 1. Flush the service line to remove debris prior to installing the meter. 2. Install suitable inlet and outlet meter valves and couplings/setters if they are not already present. • Inovonics Wireless recommends installing a shut-off valve before the meter. • Ensure appropriate space is allowed in the line for the meter and two couple gaskets. The gap from gasket to gasket should be 7 1/2 inches. • Ensure the pipe ends are aligned so that the coupling and meter threads engage without binding or cross- threading. • Make sure to adhere to local plumbing codes and regulations. 3. Remove the meters thread protectors and spud caps. • Ensure no debris enters the meter during installation. 4. Place the coupling gaskets inside the coupling nuts and set the meter in the line. • For best results, install the meter in the horizontal position, with the register di l facing upward. • The direction of the flow marked on the meter must agree with the direction of water flow. 5. Start the coupling nuts by hand, then use a wrench to tighten. • Be careful not to cross-thread the connection. 6. Make sure to support the meter if plumbing it to PVC. A. Main caseB. RegisterC.

Slowly open the valve and run enough water to dissipate entrained air and flush the line. 8. Check to make sure the meter is indicating flow. 9. Check the meter for leaks. 2.3 Complete Installation After the meter has been installed: 1. Reset the transmitter. See “Send Reset Message” on page 2 for instructions. 2. Write down the odometer’s initial meter count for entry into the TapWatch 2 software. 3. Put the meter in rapid transmit mode. “Set Modes” on page 2 for instructions. 3 Operation/Maintenance 3.1 Remove the Power Pack If it is necessary to remove the power pack: 1. Lift the outside edge of the battery pack enclosure away and up from the register to remove it. 2. Use a flat blade screwdriver to evenly lift the battery pack away from the register at the points marked LIFT HERE. Caution: Remove the power pack carefully. If the pins are not kept perpendicular with the register during removal, they may break. Never remove the power pack by rocking it away from the register. Figure 4 Remove the Battery Pack 3.2 Rotate the Register If the odometer is difficult to read, the register can be rotated. Caution: The register should only be rotated if absolutely necessary. To rotate the register, you will need to purchase a new security pin from Inovonics Wireless. The security pin used in EN1550 is meant for one use only. 1. Use a punch to drive the security pin into the register (Fig. 1). 2. Turn the register 45 degress and lift it off of the meter. 3. Remove the broken security pin from the bottom of the register. 4. Replace the register in the desired position. 5. Use your thumb to insert a new security pin. Note: If you will need to rotate the register again, ensure there’s appropriate clearance to remove the security pin in the new position. 3.3 How to Read the Meter Figure 5 EN1550 Components Flow indicator The flow indicator spins when water is flowing through the meter. Odometer The odometer displays the number of gallons used, to the nearest 10 gallons. Sweep hand The sweep hand indicates the single digit number of gallons that has passed through the meter. Each full revolution indicates 10 gallons of consumption, and will advance the first column on the odometer. The meter in Figure 5 shows a consumption of 14.6 gallons. The odomoter indicates that 10 gallons have been used, and the sweep hand adds 4.6 gallons to that number. 3.4 Send Reset Message When the EN1550 is reset, the count is zeroed and an RF reset message is sent. The RF reset message is used for registration into TapWatch software. To reset the EN1550: 1. Push an unfolded paper clip through the guide hole to press and hold the Operation button for five seconds (Figure 2). 3.5 Set Modes In normal mode, the EN1550 transmits the flow count approximately once per hour, or upon every 100 gallons of water, whichever occurs first. When in rapid transmit mode, the EN1550 transmits the flow count approximately once per minute. Rapid transmit mode is used during installation, to help ensure all your programmed end- devices are functioning correctly. A. Flow indicatorB. OdometerC. Sweep hand B A C © 2006 Inovonics Wireless - www.inovonicswireless.comPage 3 Once in rapid transmit mode, the EN1550 transmits for approximately 36 hours, and then returns to normal mode. The EN1550 can also be returned to normal mode by resetting it. This will also reset the count to zero. To set rapid transmit mode: 1. Push an unfolded pa…

Testing was performed in 3 different orthogonal axis to determine the worst case emissions from the device. The worst case emissions measurements are shown in this report. FCC CFR47 Part 15.31: Measurement Standards: In any case where the device is powered off a battery, a fresh battery was used during test. In cases where the device is powered off an AC supply, voltage was varied per Part 15.31 to find worst case emissions. FCC CFR47 Part 15.35: Measurement Detector Functions and Bandwidths: FCC Part 15.35 was utilized when performing the measurements within this report. This test report is in-part, Intertek ETL Semko was asked to test only the field strength of the fundamental and harmonics as well as the unintentional radiated emissions and conducted emissions when applicable.

FCC ID: HCQ3B6ETIMT EN1550 12. Test Report Additional Information The test report containing intentional/unintentional emissions data is attached as “TestReport_EN1550.pdf”. Intertek ETL Semko labs generated this report. Additional data demonstrating compliance with 47CFR15.247 follows. For the following measurements, the antenna was replaced by a coaxial connection to an HP8594E spectrum analyzer. Minimum Channel Separation: Plot 1 is a spectrum plot showing a minimum channel separation of 810 kHz. Compliance with section 15.247(a)(1) is demonstrated by capturing several transmissions over a small portion of the 902-928 MHz ISM band. Plot 1: Demonstration of channel spacing requirement. FCC ID: HCQ3B6ETIMT EN1550 Number of hopping Channels: Plot 2 demonstrates compliance with 15.247(a)(1)(i) — Number of hopping channels. This is a stored display of many sequential transmissions to show the overall band occupied by the transmitter Plot 2: Demonstration of 25 hopping channels. 20 dB bandwidth of a single channel: Plot 3 shows the 20 dB bandwidth of a single channel to demonstrate compliance with 15.247(a)(1)(i). The 20 dB occupied bandwidth is 276.3 kHz. Plot 3: Demonstration of occupied bandwidth.
