Ultrasonic Tank Level Sensors

Tank Level Monitoring With Ultrasonic Sensing

Ultrasonic sensors are designed for liquid level measurement in tanks, vessels, totes, drums, and separators. Migatron’s tank level sensors enable non-contact level sensing across a wide range of tank materials and sizes, helping operators reduce downtime and automate inventory management, even in Hazardous Locations or Explosive Atmospheres when using Intrinsically Safe models.

Built for Demanding Applications

Hazardous Locations Approved

Our Intrinsically Safe Ultrasonic Sensors are certified for use in hazardous gas or dust environments classified as Zone 0, 1, 2, 20, 21, or 22 for ATEX/IECEx, and Class I, II, or III for C-UL-US when used with approved intrinsic safety barrier(s). They’re engineered to perform in flammable gas and vapor environments typical in upstream, midstream, and downstream oil & gas operations.

Non-Contact Measurement

No moving parts. No contact with the liquid. Migatron sensors use ultrasonic sound waves to deliver precise level readings without risk of corrosion, buildup, or mechanical wear.

All Tank Types

Whether installed on steel API tanks, 55-gallon drums, plastic totes, or fiberglass vessels, our ultrasonic tank level sensors adapt to your setup. With adjustable sensing ranges and analog outputs, they work across varied heights and diameters, even with sloped or domed tank tops.

Outdoor Use

Designed for use in exposed locations, our sensors operate reliably in wide temperature ranges, high humidity, and dusty or corrosive environments. Many models are fully sealed and IP67-rated for added protection

Sensors for Lubricant, Oil, and Additive Storage

Lubricant, oil, and additive storage tanks require reliable level monitoring without direct contact with the fluid. Ultrasonic sensors provide a non-contact solution for measuring tank levels in lubricant blending systems, additive tanks, and day tanks used in processing.

Unlike float switches or mechanical probes, ultrasonic sensors mount above the liquid surface and measure distance using sound pulses. This helps reduce contamination, avoids moving parts, and minimizes maintenance in applications where fluids may be viscous, sticky, corrosive, or difficult to access.

Ultrasonic tank level sensors can be used for:

Lubricant storage tanks
Additive and chemical feed tanks
Fluid collection tanks
Tote, drum, and IBC level monitoring
Inventory monitoring and refill alerts
Pump control and overflow prevention

For facilities handling hazardous liquids or vapors, Migatron offers intrinsically safe ultrasonic sensor options designed for hazardous locations and explosive atmospheres.

Whether you are monitoring a single storage tank or integrating level sensing into a larger lubricant blending or fluid handling system, Migatron can deliver the right ultrasonic sensor for your environmental conditions.

Tank Level Monitoring Considerations

Before selecting an ultrasonic sensor, review the tank and application details that can affect performance.

Important considerations include:

Tank height and required sensing range
Liquid or material being measured
Hazardous area classification
Required output signal
Mounting location and available space
Foam, vapor, turbulence, or condensation
Internal obstructions such as ladders, pipes, fill streams, or agitators
Need for continuous feedback, alarm points, or pump control

For best results, the sensor should be mounted with a clear path to the target surface and positioned to avoid false echoes from tank walls, fittings, or internal structures.
