Positioning and measuring pipeline corrosion electromagnetic testing equipment gradually and GIS system and the market is now sold with GPS system, provide pipe status, location and time of the relative relations accurate record, for later drawing analysis, the main function of the yes. To conduit preventive maintenance, prolong the life of pipeline, and in the early detection of erosion.
The system includes a portable handheld transmitter and receiver. Transmitter and CPS site links, can be applied to the pipeline a special nearly dc signal. Receiver can be in maximum 30 km (19 miles) within the scope of recognize this special signal to locate the position of the pipeline and depth.
Once the pipe is positioning, technical personnel can draw along the pipeline leakage current map, showing the signal current size and the direction, so as to rapidly determine the coating damage.
Determine the pipeline damage after period, the use of A word frame, can be further will damage location and depth determined in 1 meter (3 feet) range.
With automatic signal attenuation (ASA), advanced direction of current (ACD), and adapt to the ground compensation (AGC) strong function, can even right and other metal structure lap, there are electrical interference or line dense area of pipeline accurately and easily positioning and surveying and mapping. And provide current (ACCA) and voltage gradient (ACVG) synchronous measurement. Real-time measuring current (ACCA) and voltage gradient (ACVG).
The operator does not need to complete the current span ", do not need manual calculation, can determine the usually need to direct connect to measurement along the pipe transmission of the CP (cathodic protection) current.
In any mode of surveying and mapping information, also store and display in the receiver, record of surveying and mapping information can use bluetooth transmission to the PC or optional PDA (and GPS data connection), with graphical format display for rapid analysis.
And its corollary equipment is suitable for pipeline technical personnel the latest accurate, quick and reliable pipeline current mapping tool.
receiver
Hand-held receiver even in complicated crowded area, also can be used for positioning line, measuring system transmitter applied nearly dc signal current intensity and direction, and then provide the operator.
Receiver to need operation, at the same time instantaneous display results. To provide the operator a through and metal pipe connected to locate anticorrosive coating damage and determine the cathodic protection system pipeline failure point advanced method.
transmitter
System specific power transmitter, the longest detection range can be up to 30 km (19 miles). A minimum of pipeline access points to reduce the evaluation a line of time. Transmitter has three operation modes, we can ensure that distribution piping system to effectively surveying and mapping.
Connection is very simple, the current reading and power of the light emitting diode instruction function to help the operator according to the different line, choose the best set.

software
Use GML surveying and mapping software can be real-time (through the PDA or PC) drawing analysis
Provide the operator with more rapid surveying and mapping information, can and PDA or PC machine for wireless transmission, direct upload all information, also can and GPS system nested together, through the redi GML surveying and mapping software will upload all information to the database. Every time after surveying and mapping database will be updated, and in PDA or PC can immediately to database or optional graphical format to see this change. Information can be input to most of the available standard post processing software. GML software and GPS information combination, can through the various formats display surveying and mapping data, also support for new and old mapping of contrast.
A word frame
Annex A word frame connection receiver can be carried out anti-corrosive layer damage and insulation fault accurate positioning. Receiver screen can display the fault direction, the direction of the arrow, make use of fault point more easily positioning. Also shows A word stand feet needle between dB micro voltage reading, at the same time can be on different between fault point compared to determine the most serious fault. This value can be convenient storage in a database, through the bluetooth upload to PDA or PC machine.
