Flue gas analyzers
Flue gas analysis is used to monitor the efficiency and optimize combustion processes in various furnaces, steam generators, and industrial and utility boilers. In practice, two parameters are recognized as the most important for controlling combustion efficiency. The first is the concentration of oxygen O 2 as a direct indicator of losses due to excess air supplied to the furnace.
The second parameter is the concentration of unburned combustible components, usually carbon monoxide CO and hydrogen H 2, which makes it possible to judge losses due to incomplete combustion. Cells based on zirconium oxide are the most widely used for continuous measurement of oxygen concentration in the flue and other process gases.
They are distinguished by the ability to measure the oxygen content in high-temperature, dust-laden, and water vapor-laden gases without any additional sample preparation. Such cells are also used in Thermox analyzers. Catalytic cells are used in these analyzers to measure the concentration of unburned combustible components in the flue gas. It should be noted that zirconium oxide sensors are also used to measure the ppm level of oxygen in pure or shielding gases. Recently, laser oxygen analyzers, also presented in this section, have been increasingly used.
Gas moisture analyzers
Humidity measurement is one of the most demanded tasks in the analysis of pure and process gases on stream. It presents particular difficulty in the continuous determination of moisture content in corrosive and contaminated gases. To solve these problems, we offer analyzers based on various physical and chemical principles and technologies: Piezocrystalline moisture analyzers – quartz microbalances – are distinguished by record sensitivity, including in the ppm, ppb, and even ppt ranges. Such analyzers are widely used in the reforming and production of olefins, as well as in the transportation of natural and associated gas.
Laser moisture analyzers are characterized by selective sensitivity to water molecules and insensitivity to other components of a complex gas mixture and are used mainly at natural gas metering stations. Moisture analyzers operating on the principle of a chilled mirror are used when it is necessary to determine the dew point temperature of a gas mixture from water or hydrocarbons. Electrochemical moisture analyzers based on P 2 O 5 are used in cases where moisture measurement must be carried out in relatively clean environments in the ppm range. The fundamental Faraday law, on which the measurement is based, greatly simplifies the verification and calibration procedures.
Analyzers of hydrogen in gases
Hydrogen concentration measurement is a common task of analysis in gas mixtures and process flows, including corrosive and contaminated with various impurities. To meet this challenge, Artvik offers the HY-OPTIMA family of hydrogen analyzers using a unique measurement principle. Unlike other thermal conductivity-based hydrogen analyzers, HY-OPTIMA analyzers are extremely selective to hydrogen, which allows them to be used in complex gas mixtures, minimizes the interaction of the analyzed medium components and impurities, and also eliminates the need for a reference gas.
Multifunctional calibrators are compact reference instruments designed for verification and calibration in field and laboratory conditions of various measuring instruments, including instruments for measuring pressure, differential pressure, temperature, flow, level, and electrical signals that have various analog, including pulse-frequency ( current, voltage, resistance, frequency, pulses), as well as digital output signals. Multifunctional process calibrators have wide functionality: measurement, generation, and calibration of many process parameters, which makes such devices versatile and indispensable in various industries.
Pressure measurement is carried out by internal and external modules, while the maximum number of internal modules varies for different models, and external modules are not limited. Most calibrators have a documentation function that allows using specialized software to create and download calibration tasks from a PC to the calibrator, transfer calibration results from the calibrator to a PC, generate reports, etc. Some models have the ability to calibrate/verify and trim instruments using the HART protocol, as well as the Foundation Fieldbus H1 and Profibus PA Fieldbus protocols.
Pressure calibrators are reference instruments designed for verification and calibration in the field and laboratory of pressure measuring instruments that directly display the pressure value and/or have various analog (current, voltage, relay status) output signals. Some models of pressure calibrators allow you to perform automated calibration/verification under the control of specialized calibration software (software) installed on a PC.
Temperature calibrators and precision digital thermometers
Temperature calibrators are designed for field and laboratory verification and calibration of temperature measuring instruments (SI), including glass and manometric thermometers, resistance thermometers, and thermocouples, as well as temperature relays. Setting and maintaining the reference temperature with high accuracy is carried out using a dry-well or liquid thermostat (calibration bath). Thus, in most cases, when choosing an instrument for checking and calibrating working temperature measuring instruments, it is recommended to use dry-well calibrators.
The temperature value can be set manually or using specialized software (software) built into the calibrator or installed on a PC. Measurement of the temperature of the MI under test can be carried out using the measuring section built into the calibrator or using external meters. Most versions of calibrators have a documentation function that allows using specialized software to create calibration tasks, download them from a PC to the calibrator, transfer calibration results to a PC, generate reports, etc. Precision digital thermometers are designed to be used as reference thermometers when calibrating or verifying temperature-measuring instruments.
Digital pressure gauges
Digital pressure gauges are popular due to the optimal combination of their characteristics, allowing them to be used both as pressure gauges for accurate measurements (precision pressure gauges) in process control, and for metrological support purposes as reference instruments.
Level gauges and level switches
Level gauges (waveguide, radar, buoy, and magnetostrictive) are used to measure the level, volume, and interface of media in technological processes at industrial enterprises. Level switches are used in the control of pumps, valves in technological processes, and emergency protection systems (ESD).
Flow meters and flow indicators
Ultrasonic and thermal differential flow meters are designed to measure the velocity and flow of various liquid media (effluent, water, pulp, etc.), including those containing solid particles or gas bubbles, as well as gases.
