Oil & gas tank level measurement
Distance-based level monitoring for tanks and vessels.
Ex-Rated Laser Distance Systems
Laser distance measurement systems for oil and gas environments requiring hazardous-area design awareness.
Overview
What this service covers
Laser distance measurement hardware for oil & gas and other sites where hazardous-area requirements shape the design from the first schematic. We design the circuit and interface with those requirements in mind; formal Ex-certification of the finished, installed unit is handled through your site's certification body, not by us.
Client Problems
Problems this service solves
- Distance or level measurement is needed in an area where standard electronics can't simply be installed without hazardous-area review.
- A manual measurement process needs to become automated logging in a restricted-access area.
- An existing measurement circuit needs review for power and signal isolation before it goes anywhere near a hazardous area.
Capabilities
What we do
- Laser distance measurement circuit design
- Hazardous-area design awareness (component and layout choices made with Ex-area review in mind)
- Sensor integration and signal processing
- Rugged, enclosure-ready hardware design
- Field calibration support
Technologies
Tools & platforms
Laser rangefinder modules, isolated/low-power signal interfaces, and rugged enclosure design practices suited to restricted-access sites.

Development Process
How we approach this work
- 01Site & hazard review
Understand the site's hazard classification, as provided by you.
- 02Circuit & interface design
Design with isolation and power constraints in mind.
- 03Hardware build
Build and bench-test the measurement hardware.
- 04Calibration & handoff
Calibrate and document; final Ex-certification of the installed unit is the client's/certification body's responsibility.
Deliverables
What you receive
- Schematics and PCB layout
- Signal processing documentation
- Calibration notes
Testing & Validation
How measurement accuracy gets validated
Distance readings are checked on the bench against known, measured distances before calibration is finalised, and signal isolation is verified before the circuit is considered ready for a hazardous-area review. Final Ex-certification of the installed unit is a separate step handled by your site's certification body — our validation covers the electronics we're responsible for, not the site's formal hazardous-area sign-off.
Applications
Where this is used
Hazardous-area distance monitoring

How We Can Help
How PAK-EL LAB Can Help
If you need distance or level measurement in a hazardous-area site, we can design the circuit and signal processing with your site's classification in mind, and integrate it with existing monitoring where one exists. Scope, deliverables, schedule and quotation are confirmed once we understand the site's hazard classification (as provided by you) and what's being measured — final Ex-certification of the installed unit remains your site's certification body's responsibility, not ours. We work with clients internationally and collaborate remotely as standard practice.

FAQ
Frequently Asked Questions
Do you provide Ex-certification for the finished unit?
No. We design the circuit and layout with hazardous-area requirements in mind, but formal Ex-certification of the finished, installed unit is handled through your site's certification body, not by us.
What distance range can these laser modules measure?
It depends on the specific rangefinder module chosen for the project and the target surface — we select the module to match the distances your application actually needs rather than quoting one figure for every project.
Can this integrate with existing tank-level monitoring?
Yes, the measurement circuit can be designed to feed into an existing monitoring or automation system rather than standing alone.
Do you handle installation in the hazardous area itself?
We design and build the hardware; installation and sign-off in a classified hazardous area is handled by your site's own certified personnel and process.
