Magnetostrictive level transmitter

Types of magnetostrictive level transmitter

Magnetostrictive level transmitters come in different configurations. Each type fulfills specific industrial needs. Several main types include reservoir, liquid natural gas (LNG), and high-temperature strong-pressure vessel. These transmitters differ based on their construction, operating principle, and application.

Reservoir Magnetostrictive Level Transmitters

This type of level transmitter is widely used in various industries. These include oil and gas, water and wastewater, and chemical processing. Reservoir magnetostrictive transmitters measure the liquid level in storage tanks or reservoirs. Such tools use a float that moves with the liquid surface. The float is equipped with a magnetic element. As the float moves, it creates a magnetic field that the transmitter detects. The transmitter then calculates the liquid level based on the time it takes for the magnetic pulse to travel to the float and return. This ensures that it provides accurate measurements.

LNG Magnetostrictive Level Transmitters

LNG magnetostrictive level transmitters are designed specifically for monitoring liquid gas levels in storage tanks. They also work well in cryogenic applications. These transmitters must operate accurately at very low temperatures, often below -160°C (-256°F). To achieve this, LNG magnetostrictive transmitters use specialized materials and hardened seals. They help maintain performance and accuracy even under extreme conditions.

High Temperature and High Pressure Vessels Magnetostrictive Level Transmitters

These transmitters are designed to work in environments with both high temperature and high pressure. Think of steam generation, chemical processing, and power plants. They provide a reliable measurement in extremely challenging environments. They ensure the reduction of deformation or damage to its components. They achieve this by employing rugged materials. Such materials can withstand such severe operating conditions, including stainless steel or Inconel. In addition to durability, these transmitters often have advanced electronic components. These ensure that they can provide accurate readings while maintaining stability.

Industrial Applications of magnetostrictive level transmitter

Magnetostrictive fuel level sensor plays a vital role in various industries. They also provide accurate liquid level measurements in industrial settings. From chemical processing to power generation, these devices offer key performance in challenging environments.

Oil and Gas Industry

In the oil and gas industry, magnetostrictive level transmitters measure liquid and gas levels in tanks and reservoirs. Their high accuracy and reliability make them essential tools for managing resources. In addition, these transmitters can work in hostile environments, including high pressure and high temperature. That is why they are well suited for this industry.

Water and Wastewater Treatment

In water and wastewater treatment plants, magnetostrictive level transmitters are used to monitor water levels in tanks and basins. They help manage the water treatment process by tracking levels in sludge, slurry, and other liquids. Their precision enables effective control of pumping systems and prevents overflow or dry running of pumps. Their maintenance-free operation is another benefit. It reduces the requirement for frequent sensor checks and replacements in large-scale systems.

Chemical Processing

Chemical processing facilities deal with a wide range of liquids and slurries. These include corrosive chemicals, which can be high risk. In such a scenario, magnetostrictive level transmitters provide safe and reliable measurements. They will ensure that chemical storage and processing operations run smoothly and safely.

Power Generation

Steam generators use high-pressure and high-temperature liquids. That is why power plants utilize magnetostrictive level transmitters for feedwater and steam generation. They provide accurate level measurements. This improves safety and efficiency in power generation.

Product Specifications and Features of magnetostrictive level transmitter

Important specifications and features of magnetostrictive level transmitters determine performance in various applications.

• Tank Material and Size: Choose a design that supports a wide range of tank materials. Such materials include stainless steel, carbon steel, and other alloys. The tanks also come in multiple sizes for industrial and large-scale uses.
• Temperature and Pressure Ratings: Go for one with premium materials and advanced sealing technology. Such elements allow for the safe and reliable operation of the transmitters in extreme environments. In addition, the transmitters are often rated for temperatures above 100°C (212°F). They also bear pressure ratings up to 25 bar (363 psi) or more.
• Liquid and Medium Compatibility: Consider magnetic level sensors with high versatility. Such options have strong materials of construction and premium seals that are resistant to chemical corrosion. They withstand almost any medium. This includes aggressive chemicals, viscous liquids, and slurries.
• Accuracy and Measurement Range: Look for sensors that provide high accuracy. Sensors within the range of +/-1 mm are accurate enough. Find a transmitter with a measurement range of up to 6 meters (20 feet) for industrial uses. Select one that offers greater flexibility. They will ensure they cater to various tank sizes and requirements.
• Power and Signal: Go for models with low power consumption and can run using DC power. This makes them cost-effective in the long run. For signals, choose mediums that are compatible with 4-20 mA output. They are standard in industrial applications.

How to Choose magnetostrictive level transmitter

Several key factors come into play when selecting a liquid level sensing device. Consider the industry requirements, sensor specifications, and operating conditions. They help when choosing a magnetostrictive level transmitter.

Industry Requirements

If in a highly regulated industry like oil and gas, priority should be given to safety and reliability. Sensitivity to environmental conditions is another consideration. If in a water treatment plant, choose a transmitter with high IP ratings and robust materials.

Operating Conditions

Always ensure the chosen transmitter can withstand the requirements of the working environment. For extreme temperatures and high pressure, opt for transmitters with stainless steel or Inconel housing. Such transmitters have been proven to bear such pressure.

Tank Specifications

Determine the tank material and size before selecting a magnetostrictive level transmitter. Tanks come in varying engine sizes and materials. That is why it is prudent to go for transmitters that match the tank specifications. Those with flexible housing materials are the ideal option. They will ensure they operate smoothly, whether a stainless steel tank or a carbon steel one.

Measurement Requirements

Identify the required liquid level measurement range. Go for models that offer high accuracy and a large measurement range. They will reduce the risks of overflow or running dry in large industrial tanks. Then check the output signal compatibility, ensuring it is aligned with the existing monitoring system.

Maintenance

The magnetostrictive level transmitters for liquids have a non-contact measurement. So, they have a longer lifespan and less maintenance. This is important for those in harsh and remote environments. In such scenarios, it is important to minimize regular maintenance.
