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
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.
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.
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.
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
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.
