Continuous monitoring of nutrient levels provides crucial information about daily, seasonal and event based changes in water quality conditions, and can be a strong indicator on the overall health of the water body. In recent years, monitoring of nutrients has grown in importance as it has come to the forefront in regulatory compliance of water quality in many regions.
Evaporative gas cooling and conditioning systems help protect your downstream equipment, enhance air pollution control performance, reduce gas volumes, and increase production capacity. Central to our systems are Turbotak atomizing nozzles, which introduce a controlled amount of finely atomized water into the hot gas stream to reduce and/or maintain gas temperature. The water evaporates, while absorbing heat from the gases, for free-flowing dust, zero liquid discharge, and minimal or no wall buildup.
The measurement of gas flow in large ducts or pipes offers its own set of challenges. Large ducts and pipes often have swirls or turbulence in them which makes measurement of true gas flow difficult. Sierra has developed a number of solutions to this vexing problem, including stand-alone flow conditioning elements and multiple arrays of thermal sensors. By including hot taps and purging systems, such arrays can be very flexible.
According to the International Committee on Illumination CIE recommendations, luminance should be monitored as the luminance contained within in a conical field of view, subtending an angle of 20º. It is recommended that a luminance photometer is mounted in the tunnel approach road approximately 120 - 200 metres from the portal, depending on the approach speed of the vehicles and their stopping distance. The purpose of monitoring the luminance at the portal is to adjust the level of light intensity inside...
Thermal mass flowmeters and controllers are ideal for Argon application where precision is key. Sierra specializes in accurate mass flow measurement and/or control of Argon gas. Popular applications range from general industrial process control, inerting and steel purification processes to name a few.
Sierra designs and manufactures a wide range of today’s most advanced analog and digital gas flowmeters and controllers, including a high-pressure gas flowmeter. For gas mixing and blending applications, accuracy and precision control and measurement are always a central requirement. Sierra’s precise flow meters and controls provide end-users with high performance in gas mixing and blending applications like creating artificial atmospheres, gas mixing in manufacturing, inerting and gas chromatography.
From bulk gas delivery to cleaning to purging operations, Sierra`s mass flow meters and controllers offer the simplicity and robustness demanded in these applications. Our ability to handle corrosive gases, high flow rates and multiple gases with the same unit makes Sierra`s mass flow meters and controllers a tool-makers choice.
Most chemical reactions are based on direct mass flow readings, and thus, Sierra`s immersible thermal mass flow meters and our volumetric vortex and multivariable mass vortex flow meters see extensive used in oil, gas and steam measurement. In addition, process liquid flows can be addressed with our non-intrusive clamp-on ultrasonic flow meters. Finally, our capillary thermal mass flow meters and controllers are perfect for semiconductor processing applications.
The method is intended for determination of hesperidin and naringin using capillary electrophoresis technique in order to reveal adulteration of juices. These components are tested in citrus juices, concentrated juices, nectars, juice-containing beverages, and fruit sauces that are produced primarily from oranges, grapefruits, tangerines, lemons, and limes.
Various food additives – preservatives (benzoic acid, sorbic acid, and their salts), sweeteners (Acesulfame K, saccharine and its salts) and others are widely used in food industry for the improvement of food products properties and extension of storage life. The amount of these additives in food products is regulated by technical instructions and other norms.
Low flow measurement and control is a difficult application. Ultra low flow mass flow controllers can accurately control flows from 0.1 to 0.4 sccm which is ideal for measuring and controlling doping gases for pilot plants and other research houses.
Accurate liquid flow sensor measurement can reduce water bills, determine leakage rates, and increase system efficiency. Solve accurate water and industrial liquid flow measurement requirements with clamp-on or insertion ultrasonic flow liquid flow meters featuring precision sensing elements or our complete line of multivariable mass vortex meters.
Monitoring stack emissions is a fundamental requirement for most industrial processes. Our gas analysers, dust monitors and flow monitors are designed for a wide range of applications and can operate as a fully integrated system or as stand alone instruments.
Sierra has a complete line of fuel flow measurement instrumentation. Our ultrasonic and vortex flow meters are an ideal choice for accurate filling, transport and usage fuel flow applications found in general industry. Through our Automotive Test Division, we also manufacture a line of ultra-high accuracy vehicle consumption measurement system called FuelTrak.
