A © Copyright 2007, Independent Technologies, Inc. Page 3 APPLICATION The WESROC ® Route Management System consists of a tank transmitter, a Base Unit, and a computer database host. The database host normally resides at your distribution office. Remote hosting is an option provided by Independent Technologies, Inc. for demonstration purposes and to assist during installations. Backup host services are available as an extra charge product. OVERVIEW After installation on a tank, the transmitter monitors the tank level using a Rochester R3D remote ready dial. As the fuel level in the tank changes it is transmitted to the Base Unit for display and processing. Tank low and critical thresholds are entered on the host computer for each tank. When the tank level drops below either the low or critical threshold, a report will automatically be sent to the host computer notifying the supplier of the event. A Base Unit can support up to eight individual tank transmitters at the same time. Tank transmitters may be field programmed as tank 1 through 8 (the default is tank 1). The Base Unit does not interfere with the customer’s telephone line but does require the connection to report into the host computer. If the phone line is already in use, the Base Unit will retry later. If someone, or another device, interrupts a Base Unit during its report, the Base Unit will immediately hang up and try again in about two minutes. After two attempts, it will wait 1 hour and then try to call a secondary host phone number. Base Unit reports are usually made to a local or to a toll-free number to your host computer. The Base Unit is normally positioned within 500 feet of the tank, but ranges up to 1,000 feet are possible if line of sight transmission is available. The Base Unit has a two-digit display that shows the latest level percentage (for up to 8 tanks). The Base Unit will report in, using a telephone line, on a schedule that is downloaded from the host computer. Report schedules may be hourly, daily, or weekly. The Base Unit will also report in if there is a tank fill, lo…

This equipment should be installed and operated with minimum distance 0.983cm (0.39 inches) between the radiator and your body. RF Exposure Calculations: The following information provides the minimum separation distances for the two major antenna types used in this system. Directional Antenna: The 1dBi antenna is the maximum gain antenna certified for use with the product. The minimum separation distance is calculated from FCC OET 65 Appendix B, Table 1B Guidelines for General Population/Uncontrolled Exposure. This calculation is based on the highest EIRP possible from the system, considering maximum power and antenna gain. The exposure limit for a transmitter operating at 916.5MHz is found in mW/cm^2 using the equations f/1200. Since the operating frequency in channel DA produced the lowest limit, that limit will be used in calculation. (916.5/1200 = 0.763mW/cm^2) S = (Po * G) / (4 * Pi * r^2) or r = SQRT [ (Po * G) / (4 * Pi * S) ] Where S = 0.763 mW/cm^2 for 916.5 MHz Where Po = 8.28 mW (Peak RF, 9.18dBm) Where G = 1.12 (numeric equivalent to 1dBi antenna gain with 0.0 dB cable loss) Where r = Minimum Safe Distance from antenna (cm) For Po = 8.28mW, r = 0.983cm (0.39 inches) For a distance [r] of 20cm from this antenna, the field density S = 0.0019 mW/cm^2 Notes: 1. The minimum safe distance is based on a conservative “worst case” prediction, i.e. using the formula shown above and no duty factor. In practice the minimum distance will be much shorter. (Ref. 2) 2. The minimum safe distance has been calculated for the maximum allowed Power Density (S) limit of 0.75 mW/cm^2 for the frequency 915 MHz for uncontrolled environments (Ref. 2). References: 1.

Several configurations were examined and the results presented represent a worst-case scenario. The EUT was placed on a wooden table approximately 80cm high and centered on a 4m diameter turntable. The table was rotated to find the angles of maximum emissions and the receiving antenna was moved vertically from 1m to 4m in both vertical and horizontal positions. The EUT was tested while sitting both vertically and horizontally. The horizontal configuration produced the highest emissions, and that position was used for all radiated testing. All measurements were taken at a distance of 3m from the EUT for Part 15.209 intentional radiator measurements, and 3m for 15.247 measurements of the fundamental frequency in the 902MHz to 928MHz band and subsequent harmonics. 2.0 Description 2.1 Equipment under test The Transmitter is designed to enhance the efficiency of a bulk liquid distributor’s delivery operation. The primary function of the Transmitter is to measure and report the liquid level inside of a tank via a wireless link. In addition, the Transmitter provides a variety of status, version and configuration information. The data gathered by the Transmitter is sent to a WESROC RMS Base Unit. The Base Unit relays the information to a WESROC RMS Host Computer at specified intervals via a standard telephone line. The Transmitter is intended to be installed on the outside of a tank and be connected to the sensor ready dial on a standard magnetic liquid level gauge. The Transmitter senses the position of the gauge and uses this information to calculate the liquid level in the tank. The EUT was the worst case configuration of the three models (MT-9100TNK-Sx, MT-9100TNK- Rx, MT-9100TNK-Ux).
