Ultrasonic Sensors for Oil & Gas Applications
Sensors for Oil & Gas
Migatron intrinsically safe ultrasonic sensors provide non-contact level measurement for oil and gas industry drilling, storage, and other equipment. Our sensors are used to monitor liquid levels, support high and low level alarms, and provide analog feedback to PLCs and control systems.
For classified locations where flammable gases, vapors or dust may be present, our intrinsically safe sensors deliver precise measurement and monitoring capabilities while meeting the rigorous safety requirements of hazardous locations and explosive atmospheres.
Sensors with Hazardous Area Approvals
Engineered Solutions for Oil & Gas Applications
Migatron’s ultrasonic sensors are specifically designed to overcome the challenges faced in oil and gas operations. Our intrinsically safe sensor technology delivers reliable performance in hazardous areas while providing the precision measurement capabilities essential for critical applications.
Benefits for Oil & Gas Operations:
- Intrinsically Safe Design – ATEX and IECEx certified sensors eliminate ignition risks in explosive atmospheres
- Non-Contact Measurement – Ultrasonic technology provides accurate readings without contacting potentially corrosive materials
- Reliable Level Detection – Precise monitoring of tank levels for crude oil, refined products, and process chemicals
- Durable Construction – Sensors built to withstand harsh environmental conditions and continuous operation
- Integration Capabilities – Compatible with existing monitoring systems and control infrastructure
Non-Contact Level Measurement for Oil and Gas Systems
Oil and gas operations often require reliable level monitoring in tanks, vessels, and equipment where contact-based sensors may create maintenance, contamination, or installation concerns. Ultrasonic sensors measure distance using sound waves, allowing the sensor to monitor the target from above without touching the liquid or material.
Common applications include:
- Crude oil tank level monitoring
- Refined fuel tank level monitoring
- Chemical injection tank monitoring
- Additive and blending tank monitoring
- Waste oil and containment tank monitoring
- High and low level alarm applications
Choosing the Right Ultrasonic Sensor for Oil and Gas Applications
Area of Use | Common Application | Measurement Needed | Suggested Sensor |
Pipe Handling Equipment | Pipe presence, pipe alignment, pipe transfer detection | Short-range object detection or analog position feedback | |
Valve and Actuator Systems | Valve open/closed position, actuator travel, mechanical movement | Non-contact position feedback in hazardous areas | |
Crane and Hoist Equipment | Crane travel, hoist position, moving equipment detection | Short-distance position or presence detection | |
OEM Oilfield Machinery | Skids, handling systems, packaged equipment, drilling support equipment | Custom specifications for complex application | |
Hazardous Area Object Detection | Equipment presence, target detection, cover or hatch position | Intrinsically safe short-range detection | |
Classified North American Locations | Pipe handling, valve positioning, or equipment detection in Class I, II, or III areas | 0–10 VDC analog output to PLC or control system |

Intrinsically Safe System Setup
A hazardous area ultrasonic sensing system typically includes three main components:
Hazardous Area:
An intrinsically safe ultrasonic sensor is mounted above the tank, vessel, sump, or material target.
Safe Area:
An approved safety barrier is installed in a control cabinet or protected enclosure.
Control System:
The sensor output is connected to a PLC, panel meter, or process controller.
This setup allows engineers to monitor level or distance in a hazardous location while keeping the control equipment in the safe area.
