Implemented devices with capacitive tomography technology

The general structure of the capacitive tomography system is shown in the figure above. In this system, capacitive electrodes are placed outside the tube containing the fluid and provide a non-destructive image of the tube’s cross-section and the objects or fluids passing through it. The following figure shows the fabricated laboratory sample. In this product, an external body (a smaller tube) is placed inside the main tube, and by applying electric fields to the electrodes and processing the resulting data, the cross-sectional image of the second tube is reconstructed on the computer. This image is highlighted in red.

Some facilities control the transportation of oil products through multiple pipelines. In the transportation process, different petroleum products are passed through these pipelines in sequential order. It is necessary to detect the time and manner of changing the received products on time in the reception facilities.

The laboratory product mix determination system can determine the type of passing product and the percentage of mixing of different petroleum products that have been created as a result of intermittent sending of petroleum products in a pipeline in an offline manner.

Interface detector system

The color detection and control system can be used to control the product’s concentration intelligently or to detect the type of product passing through the tube. This system can distinguish the color of the product with an accuracy of 16 million modes.

The following figure illustrates the implemented sample.

Interface detector system

In oil refineries, when petroleum products pass through pipes, operators face difficulty identifying the exact time of intersection and the type of petroleum products. Human resources must continuously extract manual petroleum samples to check the current passing product in the current procedure. The purpose of this invention is to detect the type of products passing through the pipelines automatically. In this video, you will get acquainted with the operation of this system.

SDRP-K761 Board

Advanced hardware platform, suitable for implementing software radio (ALL IN One, SDR Board)

SDRP-K761 product, made by Karafan Pardaz Company, offers an advanced and powerful hardware platform. This product includes a powerful digital processor unit and a very high-quality analog mixer. The digital processor unit consists of a Xilinx Kintex7 chip with the ability to select XC7K160 / 325/410 models. The analog mixer unit using the AD9361 chip can also act as a full-sided tuner to cover the frequency range of 70MHz to 6GHz in a full-duplex manner. SDRP-K761 can be used in various systems such as transceivers, generating or receiving a variety of signals such as TV Broadcast, Cellular, Wi-Fi, FM, etc. This product has two input channels and two output channels.

Along with the hardware, HDL codes are prepared for the AD9361 section. With the help of these codes, all the settings of the AD9361 chip can be easily done without the need for a PC. It also has a 10/100/1000 Ethernet interface and PCIe-4lane and RS232 intermediates.

Tank dewatering System

The inevitable presence of water in hydrocarbons and oil products requires tank-dewatering. The water is located beneath the products, and currently, tank-dewatering is done manually by opening the discharge valve. The manual method involves human error and loss of product. The tank-dewatering device developed by Karafan Pardaz company can automatically measure the percentage of water and hydrocarbon inside the discharge tube and warn the operator if the percentage of the hydrocarbon rises above a threshold.

One of the main advantages of this tank-dewatering device is that it does not have any physical contact with the hydrocarbon, and the sensors are mounted on the surface of the tubes. This feature increases the life of sensors, prevents corrosion, and does not block the tube’s current. Also, during the installation of the system in the tank water drainage path, there is no interruption in the tank’s normal operation. The Dewatering Tank system can detect the percent of passing water and hydrocarbon accurately and start sending alarm if the percentage of water reaches zero or below a certain threshold. In the initial product, alarms are indicated by explosion-proof LED indicators on the system.
