IG Instruments is a services company, dedicated to electronic development and certification of instruments of measurement, that groups all the activities that their owners from 1979 have carried out in the scope of the automatization, Deep strongly in the automatization of terminals of Dispaches, like in the development of special electronic instruments for meteorological engineering, hydrology developing evporimetrer equipment and infiltrometer, unique in the market, fortified with own capitals. IG Instruments is at the moment a company dedicated to a the development of new technologies in the scopes of petroleum like of hydrology, attending Argentine and Brazilian companies. Our excellent activities in the scope of the hidrométrica are the Manufacture of instruments of measurement for the area of hydrometry like for example our DataLoggers Monochannels for pluviometers and limnimeters , our pulses counters for very low frequency or VLF, the Automatic Evaporimeter class "A" tank (electronic), that it works like a meteorological power station with the appropriate control of the volume that evaporates in tank, the measurement of evaporation with a precision of the order of the micrometer, with the calculation of the volumetric expansion of the steel and the expansion of the water contained in the class "A" tank. The Electronic Class "A" tank Automatic Evaporimeter, allows the measurement of evaporation of the water contained, measurement of water evaporation, measurement of evaporation of h2o, automatic measurement of water evaporation in pattern class "A" tank, the Evaporimeter tank or the Automatic Evaporimeter, has to datalogger of automatic measurement of all variables like the Evaporation of the water, rain, solar radiation, ambient humidity, temperature of the tank, low wind speed, and additional high wind speed, wind direction altoa, humidity of the ground, temperature of the ground, battery voltage, etc. This to datalogger approximately allows about to 2000 registries all its corresponding date and hour, granting an autonomy of but of 2 months in field. The data stored in this memory can be downloaded from their of serial communication port "RS232C", or RS485. or simply reading extractable / removable memory EEPROM from any other datalogger. Like for example the DL1CH-PLUV100 or the DL1CH-LIM100 or the DL2CH-2000. For the measurement of Volumes, Speeds, we have developed an instrument that satisfies to the hydrologist and the oil tankers. The CPM-03 Counter is a developed count of measure frecquencies below 1Hz, accurately of two decimal digits. The excellent applications are, Measurement of Frequencies from 0.01Hz to 65535Hz, counter up 65535 pulses, Measurement of time to arriving 30 pulses, Measurement of Pulses during 30 seconds, Measurement of Pulses during 60 seconds, Measurement of Frequency Average in a minute, Measurement of Speed of Wind with 16 point of Anemometers factors, Measurement of Volume by means of PDMeter, Measurement of Flow by Turbines etc. All the meters curves data of each one of the instruments could be downloaded from a PC, supporting to 500 different instruments. Based on this technology, we have also developed a measuring instrument of Speed of the water in opened channels like naturals Rivers. For the measurement of speed of rivers a hydraulic windlass is used, which with its turn indicates a frequency, and from his calibration card (with 16 points or 16 Kfactors) it is possible to integrate that frequency like a series of speeds or volumes. "Guincho-Molinete" windlass its appropriate counterbalance, it is possible to measure the depth of the river, with his consequent speeds, to store these data in a removable memory EEPROM that from any other datalogger is possible to lower it to PC. As resulting from this information, is possible to extract to the profile of the river to be able to thus determine the proportions to the area and with the speed the volume of he himself. This system is denominated System of Automatic Measurement of Hydraulic Speed "SMAVH". In order to contact with us, simply type Gabriel Darío Cores, or Gabriel Cores, or gdcores in any seeking Web engine, or also he will be able to find our address in Caracas 797, with our telephone +54 (11) 4631-5620, +54 (11) 4633-4982, in Federal Capital, Buenos Aires, Argentina. Or by the name of our company in Argentina like "IG Instrumentos", or in Brazil with "PerezSteel" or "IG Instrumentos" too, with the options of IG, or all together like iginstrumentos, or, IGINSTRUMENTOS or like name of company "IG Instruments srl". Our performances, as much in the Argentine market, like in the Brazilian market, position to us at the present time like a referring one in the tasks of preventive maintenance and/or corrective. In our laboratories already we have given efficient answers of repair of equipment of high electronic complexity and light mechanics, for example "CPU Scully", "Hyrolec Modules", "Plates of Accuload II", "Plates of ESI-Sorrento Controller", "Plates of CPU GatePack", "magnetic Card readers", "Display POS", "Consoles of Masters Meters", "SetStop Valves", "Meters Prime 4", "Detectors of Level". When we were with the challenge to make calibrations with Meters Masters (GateCity), (some time back we represented "GateCity" in "O.E.A."), we verified that the originating console with the own Masters Meters did not allow us to visualize all the events that were success in each bullfight. We imagined an equipment that can offer real information us of the pulses (A and B), the suitable sequence, the suitable volume, and that alerts to us when some event generates errors in the bullfight. Situations very complicated have always appeared us to solve in the scope of the programming in Assembler de Microprocessors and/or Microcontrollers, because the tools of programming are very few available. In fact nowadays these microcontrollers in languages like the "C" program themselves that already has important tools of programming. We remembered cases of implementation of mathematical routines of floating point (Everything in Assembler) for microcontroller. The objective of these routines is to obtain a precision adapted in some calculations that the equipment must report, without it requires of matrix calculations or complex series or but. Our old friends Joao Ivo Avelaneda de Souza, or Joao Ivo de Souza, or Joao Ivo Souza, or better still IVO, is always motivating us to develop new instruments and new horizons... to him a great hug. ..y other as Guillermo "Memo" my personal friend.
