The principle of operation of the magnetization device: The device consists of two compact blocks made of non-magnetic material connected by a flexible magnetic circuit. In each block there is a permanent magnet made of neodymium-iron-boron alloy (Ne-Fe-B). When installing the blocks on the surface of the part, a closed magnetic circuit is formed with the direction of the magnetizing field from one pole to the other. Above the defect scattering fields, magnetic powder particles are deposited to form an indicator pattern. Design features and advantages of the device for magnetic particle control UN-5 The delivery package with the device includes a portable case, an inter-pole jumper installed during transportation, and a liner for fixing blocks with permanent magnets. The UN-5 portable device does not require electrical power and therefore can be used where the supply of stationary power is difficult or impossible under regulatory documents: in the field, when working at height, for inspection of capacitive equipment operating under pressure, etc. - The device is easy to use, lightweight and small-sized, working with it does not require special physical and technical training from the operator; - Flexible magnetic core allows you to use the device to control parts of complex shape; - The UN-5 magnetizing device is distinguished by an increased quality of the indicator pattern and an increased control zone due to a reduced uncontrolled zone near the poles and an improved ratio of the normal and tangential components of the magnetic field (Russian patent No. 60732); - The technical characteristics of the device comply with Russian and foreign regulatory documents, this being the reason of its widespread use in more than 40 countries, including Germany, France, Brazil and Norway. When monitoring, the controlled area is the central part of the area located between the magnetic poles of the device. The width of the monitored area is determined by the width of the magnetic poles of the device and is approximately 60 mm. The length of the monitored section depends on the inter-pole distance. the dimensions of the controlled area are given depending on the device's inter-pole distance: Inter-pole distance, mm 95: 75 55 Controlled area between the working poles, mm: 60x60 40x60 25x55 The length of the defect detection zone depends on the distance established between the working poles of the magnet on the controlled product. Defects are not detected in the areas adjacent to the poles of the magnet. The length of these sections is 18 mm with an interpolar distance of 95 and 75 mm. With an interpolar distance of 55 mm these sections are 13 mm long. Scope of application: Magnetizing devices for magnetic powder flaw detection are used in many industries, including railway, water and aviation transport, in the construction and operation of pipelines, in chemical and petrochemical production. The flexible link between the magnetic blocks allows the control of products of complex shape, for example, cylindrical tanks, high-pressure apparatuses, main pipelines, etc. When checking for defects, the device can be used together with other auxiliary equipment for: - preliminary and subsequent demagnetization; - application of a magnetic indicator (which can be dry or in the form of an emulsion); - magnetoluminescent control (with ultraviolet lamps).

The Volga Triton pressure-free hybrid flow meter is designed to measure the volumetric flow of liquid in water ducts with a pressure-free and combined pressure-free flow mode. The submerged primary speed converter operates on the basis of the Doppler effect, emitting an ultrasonic signal towards the flow and receiving an echo reflected from particles in the flow with a frequency different from the frequency of the emitted signal. This frequency shift is called the "Doppler Shift" and it is proportional to the flow rate. A non-contact ultrasonic primary converter VBN-DG-01 or any other third-party liquid level converter with a unified current output of 4-20 mA can be used as a depth meter: radar, hydrostatic or ultrasonic. The volumetric flow rate is determined both by the "area-speed" method and by MI2220-2013, depending on hydraulic conditions. In non-contact (radar) mode, the Volga Triton flowmeter is designed to measure the volumetric flow rate of a liquid in a non-pressurized flow mode. The flow meter can be used as part of waste water metering units in non-pressure (gravity) sewage systems, open irrigation and reclamation channels, open or underground derivational non-pressure water pipelines of hydropower facilities, diverting supply and recirculation water pipelines of thermal power and other hydraulic structures with a non-pressure flow regime. The measurement technology is based on a non-contact radar method for measuring surface flow velocity and a non-contact ultrasonic/radar method for measuring water level. As a water level meter, both the proprietary ultrasonic level sensor BP-G-01 and third-party sensors connected via unified digital or analog interfaces, for example, VEGAPLUS, can be used. The pressure-free hybrid flow meter "Volga Triton" became the winner of the International Environmental Award EWA Award 2021 in the nomination Best technology. Secondary converter It is available in both stationary (~220 V) and portable versions with autonomous power supply. Primary converters VBN-DS-01 Primary speed converter for medium and large water pipelines VBN-DS-02 Combined primary speed and depth converter for medium and small aqueducts VBN-DS-03 is a combined low-profile primary speed and depth converter for small aqueducts.

Ecofizika-500 is a multifunctional modern platform for building complex measuring systems. The developed software makes it possible to fully use the powerful hardware potential of the system in tasks requiring the use of complex computational algorithms. Ecofizika-500 is not just another multi-channel frontend designed to transfer unprocessed data to a computer; it is an independent measuring device capable of calculating a huge number of quantities in real time, storing them in its own memory and (or) issuing them to a telemetry channel. The device can be used, including in offline mode, as a data logger, which is very important when testing complex equipment that limits the presence of the operator. Ecofizika-500 has an approved type of measuring instrument and methodological support for measuring acoustic and vibrational quantities.
