By combining the global positioning system "GPS", with the personal computer "laptop" and the mixing of advanced radio technology with advanced microprocessors, it is now possible to monitor isolated areas that were impossible to interrogate with conventional remote monitoring techniques using the remote monitoring interrogation system (RMIS). It can take up to 600 readings a day, they can be recorded depending on traffic conditions and at speeds from 8 Km - h to 160 Km - h. RMIS equipment is powered by a long-life size C lithium-thionyl chloride battery with a life expectancy of 10 years depending on the frequency of use. (Normally using the interrogation module between one and three times a year). It has the ability to receive electrical power C.A. normal (110-220 VAC, 50-60 Hz) when available, such as inside rectifiers, anode box or internal plant applications) It has an operating temperature between -40°C and 85°C in 100% humidity, meeting military specifications for any type of environment or application. The electronics are encapsulated in a level grade resin layer that prevents moisture migration in the electronics and any weakening of the resin in saturated seawater conditions.

FEED TO OIL REFINED PRODUCTS PIPELINE FROM TUXPAN VERACRUZ STORAGE & RECEPTION TERMINAL TO SAHAGÚN HIDALGO STORAGE & DISTRIBUTION TERMINAL PAG: 17 of 18 TRANSFORMER - RECTIFIER TECHNICAL SPECIFICATION REVISION: A PROYECTO # 1 14 231 1 14 321-TH-EL-SP-001 It is built using military electronics grade and its enclosure is made of materials for high impact and high content of black carbon in order to eliminate degradation by exposure to ultraviolet. It has a unique serial number assigned to it and it is registered in its GIS map by the GPS system that will permanently locate the module. This allocation is established in the field at the time of installation. It is important to note that the number of Dart Plus RMI concentrates in one area (such as in a pipeline corridor) does not matter. The system will only take the corresponding modules or serials and will have no effect towards other modules in the corridor even if they are touching each other. When interrogated by an RF connection, with its assigned serial number, it will respond by sending the stored readings and at the same time provide the operating voltage of the Lithium battery and synchronize the time of the remote module with the GPS time on the PC of the Laptop. The Dart Plus RM wireless communication system has an effective range of 30 to 325 feet (9 m to 100 m) for modules installed below ground level in valve boxes, buffalo boxes, buried directly in the ground, etc. The Dart Plus RM's wireless communication system has an effective range greater than 3,000 feet (1,000 m) for modules installed above ground level on test posts and interrogated from a car, truck, boat, helicopter, or airplane. The band for the Dart Plus RM wireless connection system for North America does not require a license in 902-928 Mhz ISM using communication frequency with “Hopping Spread Spectrum” technology. It has an internal clock with a precision of “days/minutes/month”, when it is operating at maximum operating temperature. This clock is reset / reset each time the remote module is powered, through the use of ultra low power RF microprocessors and TransmittersReceivers, and the use of power controllers via software in the "standby" mode of operation. It has three analog monitoring channels. The normal range is ± 7.0 volt for readings with reference cells with internal impedance of 20 meg-Ohm, ± 250 V for the voltage output of rectifiers, ± 150 mV for the current output of rectifiers in the shunt with rejection capability 60 Hz AC and a Transient Voltage trapping capacity of 2500 volt. Other working ranges are available for special applications. It has an accuracy of 1 mV or less in all reading ranges, regardless of the reading range being used. Provides the current output of a sacrificial anode, as well as the Instant On/Off reading, in compliance with DIN 50925 Stelth 7 standard (reference cell Ag/AgCl), using one amp, dual contact, zero power at latching relay. Measure and store 12 readings on each channel, at the interval programmed in the field, from 1 min to 30 days. It is conveniently designed to be housed in a "top hat" style on test posts under the Cott Manufacturing trade name "FINK" and "Bullet Box" Test post that is produced and manufactured by Borin Manufacturing, INC. This consideration maintains easy compatibility of the Dart Plus RM enclosure with existing test stations that have been previously installed.
