What are the different ways to measure Level in a tank?

Level in a tank can be measured using several methods, based on requirements. Simple Visual Indication using Sight Glasses / Level Gauges with Scale, Discrete Level Switching with mechanical float switch families, Continuous Level Monitoring with Electronic Level Transmitters, Non-Contact Level Measurement with ultrasonic or Radar/GWR Sensors, and Combination Value-Add Solutions like Barksdale Levelsite®.

How do I choose the right level product for my application?

Start by deciding what you need: Single Level, Multi Level, Visual Indication, or Continuous Monitoring. Consider factors like Media, Ambient Condition & Environment, Application Requirements, and Certifications. Products like Barksdale Levelsite® offer flexibility by combining multiple features.

Level

Accurately detect and control fluid levels

Name: Level Products
Brand: Barksdale

Industries that rely on monitoring liquid levels, such as in hydraulic reservoirs or industrial storage tanks, face significant challenges due to harsh operating conditions like extreme temperatures, pressure fluctuations, and corrosive environments. These factors can compromise the accuracy and reliability of standard level measurement and instrumentation.

Additionally, maintaining precision across multiple levels within a system, especially in complex or customized applications, often proves difficult. Regular maintenance in hard-to-access areas also leads to increased downtime and operational costs. As industries demand more accurate and resilient solutions, the complexity of managing fluid levels becomes an ongoing challenge.

Frequently Asked Questions

Find answers to common questions below

A1: Level in a tank can be measured using several methods, based on requirements. • Simple Visual Indication using Sight Glasses / Level Gauges with Scale: Directly show liquid level through a transparent tube or window.  • Discrete Level Switching: Barksdale has multiple mechanical float switch families where floats trigger a switch at set points for pump control or alarms. Multiple floats can be used for multi-point control in a variety of different configurations, side, top for overfill protection or bottom to prevent running dry. • Continuous Level Monitoring: Electronic Level Transmitters can provide a continuous signal proportional to liquid level (reed chain, capacitive, ultrasonic, etc.). • Non-Contact Level Measurement In case of harsh or protected media, ultrasonic or Radar/GWR Sensors can be used for non-contact level measurement. • Combination Value-Add Solutions Some products, like Barksdale Levelsite®, combine visual indication, discrete switching, and continuous level output in one device. This allows operators to see the level, automate control, and monitor trends—all with a single installation.

A2: Start by deciding what you need: • Single Level: For simple high/low point detection (e.g., pump control, alarms). • Multi Level: For monitoring multiple points in the tank. • Visual Indication: If you want to see the liquid level directly. • Continuous Monitoring: For a real-time, proportional output of the liquid level. Next, consider these factors: • Media: What liquid or material are you measuring? Check density and viscosity. • Ambient Condition & Environment: What’s the operating temperature and pressure? Is the tank indoors or outdoors? • Application Requirements: Are there size constraints or special installation needs? • Certifications: Do you need agency approvals for safety or compliance? Tip: Some products, like Barksdale Levelsite®, combine visual indication, switching, and continuous monitoring in one device for maximum flexibility. Can I get both level visual indication and level discrete monitoring (switching) in one device? Yes. Some products, like Barksdale Levelsite®, combine visual indication, discrete switching, and continuous level output in a single device for comprehensive monitoring and control.

A3: Mechanical switches use floats or moving parts to trigger contacts at set levels. Electronic switches use sensors for digital or analog outputs, offering advanced features like adjustable setpoints and diagnostics. Barksdale provides both types, including electronic models with digital displays and IO-Link connectivity.

A4: Check if the product is suitable for your liquid’s density, viscosity, and chemical properties. Barksdale level products are available in various materials to handle water, oil, chemicals, and more.

A5: Many level products are available with agency approvals (such as ATEX, IECEx, UL) and high IP ratings for use in hazardous or demanding environments. Barksdale offers certified solutions for these applications.

A6: Choose probe length and mounting based on tank size, required measurement points, and installation constraints. Barksdale provides a range of options for different tank geometries and access points.
