Product DescriptionProduct Description Rosemount 3301 Radar Level TransmitterTo understand the functionality of the Rosemount 3301, it is essential to grasp the underlying radar level measurement technology. Radar level transmitters operate based on the principle of time-of-flight (ToF) measurement. The device emits high-frequency electromagnetic waves (typically in the microwave range, such as 6 GHz, 24 GHz, or 80 GHz) towards the surface of the liquid or solid being measured. These waves travel through the vapor space above the medium, reflect off the surface, and return to the transmitter's antenna.The Rosemount 3301's sophisticated electronics then calculate the time taken for the waves to travel to the surface and back. Using the speed of light (a known constant), the transmitter converts this time into a distance, which is further translated into a level measurement. The formula governing this calculation is relatively straightforward:Distance = (Speed of Light × Time of Flight) / 2The division by 2 accounts for the round trip of the electromagnetic waves.One of the key advantages of the Rosemount 3301's radar technology is its immunity to external factors that often affect other level measurement devices. For instance, changes in temperature, pressure, density, or viscosity of the medium have minimal impact on the accuracy of the radar measurement. Additionally, the presence of dust, vapor, or foam in the vapor space does not significantly interfere with the electromagnetic waves, ensuring reliable operation in challenging conditions.1. Key Features and Specifications of Rosemount 3301The Rosemount 3301 Radar Level Transmitter is packed with features that enhance its performance, reliability, and ease of use. Below are the key features and technical specifications that set it apart from other level measurement devices in the market.1.1 High Accuracy and PrecisionAccuracy is a critical factor in level measurement, and the Rosemount 3301 excels in this regard. The transmitter offers a measurement accuracy of ±0.1% of the measured range for most applications, ensuring that plant operators can rely on precise data for process control and inventory management. Additionally, the device provides a high resolution of up to 0.1 mm, enabling it to detect even the smallest changes in level, which is essential for applications requiring tight process control.1.2 Wide Measurement RangeThe Rosemount 3301 is designed to accommodate a wide range of measurement requirements. Depending on the model (GWR or non-contact), the measurement range can vary from as low as 0.1 meters (0.33 feet) to as high as 30 meters (98.4 feet) or more. This versatility makes the transmitter suitable for use in small tanks, large storage vessels, and everything in between. For example, in oil refineries, the 3301 can be used to measure the level of crude oil in large storage tanks (with ranges up to 30 meters) or the level of chemicals in small process tanks (with ranges as low as 0.5 meters).1.3 Robust Construction for Harsh EnvironmentsIndustrial environments are often characterized by extreme temperatures, high pressures, corrosive substances, and mechanical vibrations. The Rosemount 3301 is built to withstand these harsh conditions, thanks to its durable construction materials and rugged design.Temperature Resistance: The transmitter can operate in a wide temperature range, from -60°C (-76°F) to 250°C (482°F) for the electronics and up to 400°C (752°F) for the probe (in GWR models), making it suitable for applications such as high-temperature boilers in power plants or cryogenic storage tanks in the chemical industry.Pressure Resistance: It can handle pressures ranging from vacuum (down to 0.1 mbar) to 400 bar (5800 psi), making it ideal for high-pressure applications like reactors in the petrochemical industry or pressure vessels in the pharmaceutical sector. 2.Applications of Rosemount 3301 Radar Level TransmitterThe versatility and robustness of the Rosemount 3301 make it suitable for a wide range of applications across various industries. Below are some of the key application areas where the transmitter is commonly used.2.1 Oil and Gas IndustryThe oil and gas industry presents some of the most challenging level measurement scenarios, including high temperatures, high pressures, corrosive media, and large storage tanks.Upstream Applications: In upstream operations, such as oil wells and production platforms, the 3301 can be used to measure the level of crude oil in separators, storage tanks, and production vessels. The transmitter's ability to withstand high pressures (up to 400 bar) and temperatures (up to 250°C) makes it ideal for these harsh environments.2.2 Chemical and Petrochemical IndustryThe chemical and petrochemical industry involves the handling of a wide range of corrosive, toxic, and volatile media, requiring level measurement devices that are both accurate and reliable. The Rosemount 3301 meets these requirements, with its corrosion-resistant construction and advanced signal processing capabilities.Interface Measurement: Many chemical processes involve the separation of two immiscible liquids (e.g., oil and water, or solvent and water).2.3 Power Generation IndustryPower plants, whether thermal, nuclear, or renewable, require accurate level measurement for various applications, such as boiler water level, condensate storage, and fuel oil storage. Boiler Water Level Measurement: In thermal power plants, the level of water in the boiler is a critical parameter that must be closely monitored to ensure safe and efficient operation. The Rosemount 3301 GWR models are often used for this application, as they can provide accurate measurement of the boiler water level even in high-temperature (up to 400°C) and high-pressure (up to 200 bar) conditions. The probe's robust construction (made from 316L stainless steel or Inconel) ensures that it can withstand the harsh environment inside the boiler.Fuel Oil Storage: In power plants that use fuel oil as a backup fuel, the Rosemount 3301 is used to measure the level of fuel oil in storage tanks. The transmitter's corrosion-resistant antenna and ability to measure low dielectric constant liquids (such as fuel oil) make it ideal for this application.SpecificationMeasurement principleGuided wave radar with time domain reflectometry (TDR) technologyOutput signal4-20 mACertification and StandardsATEX, CE, CSA, FM, IECExPower supply11-42 VDC-4-8Communication Protocol4-20 mA/HART,ModbusProtection LevelIP66 / NEMA 4XWork pressureFull vacuum to 40 bar (580 psi)Installation methodTop mountingCompany Profileabout usMain productKeRui (WeiFang) Automation Equipment Co., Ltd. is specialized in industrialautomation instrument development, production and sales, technical servicesand supporting equipment supply of specialized companies.
