  • Compare popular resistivity meters with FlashRES

    Although most resistivity meters nowadays can collect resistivity, IP and SP data and most of these systems are multi-channal resistivity meters, there is still a technical gap between traditional and next generation resistivity meters. FlashRES has six to 8 times more channel than traditional system, this means larger data quantity, which could help the resistivity inversion image ...

  • The key advantages of FlashRES resistivity meter

    FlashRES-UNIVERSAL is the first instrument in the world that can fully utilise all its electrodes during data collection.  It is a significant technological breakthrough. FlashRES-UNIVERSAL has following key advantages: FlashRES is a 61-channal resistivity/IP system and it is extremely fast For each current injection, conventional resistivity systems usually collect ...

  • The exploration depth of FlashRES resistivity meter

    The formula for calculating the maximum depth is universal for all resistivity meters. The exploration depth depends on the survey line length. the survey depth is usually 20-25% of the survey line total length. For example, for 10m takeout cables, the total length of the cable is 10m*63=630m and this means the exploration depth is 0.2*630m to 0.25*630m. The resolution is 10% of ...

  • The suitable battery for FlashRES resistivity meter

    Air freight battery pack is extremely diffculty in Australia, this makes installing internal battery to FlashRES resistivity meter counter-productive for ZZ. We thus use an external battery and connect it with our system. The correct external battery for our system should be a 12 volt truck/car battery of ≥ 90 Amp/hr is needed. Reference ...

  • What is 61-channel resistivity meter?

    FlashRES resistivity meter has 64 electrodes, it uses one common ground electrode, two electrodes as current injection electrodes. For each current injection between A and B, the FlashRES resistivity meter measures the potential on remaining electrodes against the common ground electrode. In this way, 61 MN voltages are measured and hence FlashRES is a 61 channal resistivity meter. ...

  • Resistivity system voltage output

    One limit of FlashRES resistivity meter is its voltage output. It can output maximum voltage of 350v, this is because the multi-core cable of the FlashRES cannot withstand voltage over 350v. the multi-core cable contains 32 small wires, voltage higher than 350v will damage these wires and make the cable short circuit. We thus limit the maximum voltage output for safety reasons. Reference ...

  • 3D Resistivity survey case study

    The challenge with all 3D electrical resistivity surveys is that the sizable amount of information points needed. this can be to retain a high enough resolution despite the extra dimension. Conventional electrical resistivity meters with sub-units or switchers for 3D survey. The FlashRES electrical ...

  • Brüel & Kjær’s radiation-resistant accelerometers

    Carrying out vibration measurements in harsh industrial environments is much easier for engineers with Brüel & Kjær’s new Type 8347-C Accelerometer. The Type 8347-C accelerometer can withstand temperatures ranging from -196°C (-321°F) to +482°C (+900°F) and has high resistance to radiation. The shear design ensures the accelerometer  superior thermal ...

  • Surface-point resistivity survey case study 1

    Surface-points electrical resistivity surveys area can be used to detect one or several known underground anomalies in timely manner. A minimum of one borehole is needed to carry out Surface-points electrical resistivity surveys. A FlashRES electrical resistivity meter allows users to position active electrodes anywhere they want in the borehole, by conducting the survey in a surface-borehole ...

  • Superior abrasion resistance demanded by sump cleaning

    Acquired by a open pit mining company located in the Minas Gerais province for a slurry application (up to 60% solids concentration) in a sedimentation sump, the Grindex Bravo 60 pump lived up to its name, proving it's the ideal solution for a wide range of similar installations. In this case ...

  • Surface resistivity survey case study 1

    The purpose of this surface electrical resistivity survey was to delineate the event direction of a gold ore deposit. The surface electrical resistivity survey uses a 10m interval cable, that permits the FlashRES 61 channel resistivity meter to detect depth up to 120m. The depth is dependent on the cable length.  The system found an occasional resistive band from 0-350m. This knowledge was ...

  • Panama Canal: Boat Towed 3D Resistivity Surveys - Case Study

    The Panama Canal Authority (ACP) needed to expand the canal in order to accommodate larger ships (and more traffic)—but first, they needed to know two things: what types of sediment loads needed to be dredged out—and more importantly—how much these loads would cost. That’s where AGI marine resistivity imaging ...

  • The evolution of thermal mass flow meters

    Who were some of the pioneers in thermal mass flow technology? A. Thermo-Systems, Inc. (TSI) began in its founder’s basement in 1959, with a cooled-film anemometer designed for transient measurements in high temperature fluid flows. This led to TSI’s hot-film and hot-wire anemometers, the first commercial products of this type. These immersion-type devices were used mainly as ...
