Level measurement is crucial in various industrial processes as it directly impacts operational efficiency, safety, and profitability. Accurate level measurement ensures that different enclosed systems maintain optimal levels of raw materials and finished products, preventing overflows, equipment damage, or process interruptions that can lead to costly downtimes. Level measurement can be achieved using level measurement instrumentation tools. These tools precisely measure the level of liquids, solids, or powders within a container or system, ensuring proper process control, safety, and efficiency. Level sensors, level transmitters, and level switches are some popular examples.

How Do Level Instruments Work?

Level instruments employ various sensing technologies to precisely measure the height of materials within a system, adapting to the specific characteristics of the substance being measured, such as its state and properties. For instance, electronic sensors, such as ultrasonic and radar sensors, work by emitting waves. The waves are reflected off the material surface, and the time it takes for the echo to return is measured, calculating the distance. Capacitive sensors detect level changes based on alterations in capacitance caused by the proximity of materials between conductive plates. Each type has its unique advantages, making them suitable for different applications. This ensures operations remain safe, efficient, and within regulatory compliance.

Types of Level Instruments Offered By JM Industrial

Our inventory comprises a variety of used level instruments for sale. Here are some popular types of level instruments we have.

  • Level probes: Level probes are direct contact instruments used to detect the presence or absence of a material at a specific point. Conductive probes rely on electrical conductivity to sense the level of conductive liquids, capacitive probes measure changes in capacitance caused by a material between two conductive elements, and vibrating fork probes detect changes in vibration frequency when submerged in a material, suitable for solids and liquids.
  • Level sensors: Level sensors continuously measure the level of a material and provide a proportional output. Ultrasonic sensors use ultrasonic waves to measure the distance to a materials surface, radar sensors use microwave radar signals to determine the level by measuring signal return time, and optical sensors use light reflection or interruption to detect the level, ideal for clear liquids.
  • Level transmitters: Level transmitters convert the level measurement into a standardized signal for remote monitoring and control. Hydrostatic transmitters measure the pressure exerted by the fluid column above the sensor for liquid level measurement, magnetostrictive transmitters use a magnetic float and waveguide to determine the level based on float position with high accuracy, and differential pressure transmitters measure the pressure difference between two points, commonly used in closed tanks or vessels

Why Consider Used Level Instruments for Your Applications?

Used level instruments benefit you in many ways, primarily if you work within tight budget constraints. Here are some pointers that will help you understand why you should consider using level instruments.

  • Immediate Availability: Ordering new instruments can sometimes have extended lead times. This can be due to manufacturing or shipping delays. Used equipment may be available immediately, which is crucial if you need a quick replacement or are under tight project timelines.
  • Sustainability: Purchasing used equipment is an environmentally-friendly choice. It increases the life of the level instruments and reduces waste. Also, it reduces the need for new raw materials and resources required to produce new ones, contributing to sustainability efforts.
  • Depreciation: Level instruments depreciate over time like any other electronic equipment. Buying used equipment allows you to avoid the initial depreciation once new equipment is purchased and put into service.
  • Proven Performance: Used level instruments have already been operational. Therefore, you can often obtain real-world feedback on their performance and reliability. This can help you make an informed decision, especially if the model has a record of durability and accuracy.
  • Flexibility: Used instruments provide a cost-effective way to get the necessary tools without investing heavily in state-of-the-art equipment or applications where advanced technology and infrastructure may not be necessary.
  • Cost Savings: This is the most apparent benefit of using level instruments. This can be particularly appealing for small businesses or startups that need to stretch their budget further.


Although used level instruments have multiple advantages, its important that the instruments are properly calibrated and in good working condition. Always consider the support and service options available, as these can impact the long-term usability of the instruments. At JM Industrial, we ensure the product meets all these conditions.

Factor Considerations While Choosing Level Instruments

There are several factors to consider when selecting appropriate level instruments for your applications. Some key considerations are as follows.

  • Type of Material: Be it any level instrument – used level sensor or used level transmitter, it is essential to determine the material to be measured. Different materials may require different types of level measurement technologies. For example, a guided wave radar or a mechanical float system could better suit non-corrosive liquids, while non-contact radar might be preferable for corrosive liquids.
  • Process Conditions: Next, consider environmental and process conditions such as pressure, temperature, and the presence of vapors or turbulence. High temperatures and pressures can affect the durability and functionality of level sensors, so its important to choose instruments that can withstand these conditions.
  • Accuracy Requirements: The required level of measurement precision can vary depending on the application. Industries like pharmaceuticals and fine chemicals demand high accuracy, while slightly less precision might be acceptable in water treatment or bulk storage.
  • Installation Constraints: Check the availability of the physical space for installing the level instrument and accessibility for maintenance. Some instruments require direct contact with the medium, while others can be mounted non-invasively.
  • Material Compatibility: The construction materials of the level instrument should be compatible with the process media. This helps prevent corrosion, degradation, and contamination.
  • Maintenance and Serviceability: Consider referring to the manufacturer’s guidelines on how to maintain and calibrate the instrument. Devices that require frequent cleaning or recalibration might increase downtime and operational costs if not properly maintained.
  • Regulatory and Safety Requirements: Ensure the instrument meets industry standards and certifications. This mainly applies in regulated industries like food and beverage, pharmaceuticals, or oil and gas. Depending on the industry, the prerequisites explosion-proof certifications in hazardous environments, materials of level instruments and hygiene-related regulations, and more.
  • Cost of Ownership: In addition to the initial purchase price, consider the total cost of ownership, which includes installation, maintenance, and potential downtime costs.
  • Vendor Reputation and Support: Finally, choose a vendor with a good reputation for quality and reliability. Also, check the level of technical support and warranty services they offer.


By carefully evaluating these factors, you can select a level instrument that optimally suits your operational needs, budget, and long-term reliability expectations.
