ADIPEC 2026 is here!

We are pleased to be at ADIPEC in Abu Dhabi, connecting with industry professionals, EPC contractors, refinery operators, consultants and partners from India and across the global energy sector.

At Cognesense, we bring together specialized solutions in tank protection and safety, tank gauging, instrumentation, automation and environmental monitoring.

We look forward to meaningful conversations, exploring new opportunities and strengthening collaborations with India's growing energy and infrastructure sector.

If you are attending ADIPEC, do visit us!

Hall 8 | Stand 8533, 2–5 November | Abu Dhabi
Let's connect!

10/30/2026

ADIPEC opens on Monday. Here are the four conversations our team is set up for at Hall 8, Stand 8533, and what to bring to each.

1. Evidence for your next risk survey
For asset owners and risk managers. Bring a tank list or last year's survey recommendations, and we will walk through where the evidence gaps are.

2. Packages built for handover
For EPC teams. Bring a package list or data sheet. We will show how instrument, tank, and hazardous-area packages can report into one record from day one.

3. An inventory and accounting review
For terminal, inventory, and finance managers. Bring a recent gain/loss or reconciliation report, and we will show how losses get traced instead of written off.

4. A classified-area walk-through
For HSE managers. Lighting, signaling, enclosures, mobile equipment, and pressure instrumentation, side by side.

Every one of them ends at the live Clairvoyance kiosk, where you can see that equipment's readings land in one audit trail, next to noise, dust, and air-quality data from the site boundary.

See you in Abu Dhabi.

Tank gauging. Fuel inventory and accounting. Explosion-proof equipment. Emissions data.

How many vendors is that on your site?

Next week at ADIPEC, it is one. Cognesense brings its heritage brands to Hall 8, Stand 8533, around a single idea: lower risk, lower emissions, better evidence.

On the stand:
- Contain emissions: radar tank gauging and overfill prevention, conservation vents and flame arresters.
- Account for every barrel: FuelsManager fuel inventory and accounting software, from tank gauge to closeout report.
- Prevent incidents: explosion-proof LED lighting, SIL 2 beacons and sounders, a flameproof motor starter and enclosure, a scale-model explosion-protected forklift, and a flameproof differential-pressure transmitter.
- Prove it all: a live Clairvoyance kiosk showing readings from mixed instruments, including inventory data, landing in one time-stamped record, with noise, dust, and air-quality data from the site boundary alongside.

Our product specialists from every brand will be there to talk through real applications.

Know your inventory. Control your fuel. Optimize your terminal.

On many terminals, gauging, loading and accounting run on separate systems. When a tank shows a loss, someone spends days reconciling numbers that never agreed.

Varec has worked on that problem since 1928. FuelsManager brings it into one platform: inventory management from the tank gauge, terminal automation at the load rack (rack control, driver entry, bills of lading), and inventory accounting with gain/loss analysis and reconciliation.

The field side comes from Cognesense too: Varec float-and-tape gauges, L&J Technologies radar and the Varec 8810 RTU, so the data runs from gauge to screen with no gap between vendors.

Terminal managers and fuel accounting teams: when a tank shows a loss, how long does it take you to trace it?

On the same stand, Shand & Jurs covers the vents and flame arresters on that tank.

Better measurement. Smarter tank operations.

Most decisions on a tank farm start with one number: the level in the tank. Receipts, transfers, overfill margins and reported inventory all depend on it.

Since 1976, L&J Technologies has focused on tank level gauging for bulk liquid storage: non-contact radar, servo and float-and-tape gauges, plus alarms, switches and overfill prevention.

For terminal and refinery engineers, the practical point is choice. Product, tank and accuracy needs differ, so the gauge should fit the application, not the other way around.

A question to take into ADIPEC: if an auditor asked how each gauge was chosen and verified, how fast could you answer?

The level is half the story. On the same stand, Clairvoyance turns it into inventory, and Shand & Jurs protects the tank.

Shand & Jurs has built tank safety equipment for that job since 1922: conservation vents for normal breathing, emergency vents for fire-case relief, flame arresters to keep an external flame out, plus gauge hatches and fittings for safer access.

One detail worth knowing: the industry standard reference for vent leakage is 1.0 SCFH at 80-90% of set pressure. Expanda-Seal vents leak less than 0.5 SCFH at 95%. Less leakage means less product lost to evaporation.

Tank engineers at terminals and refineries: when did you last check if your vents leak just below set point?

The same tank needs an accurate level, too. L&J Technologies gauging is on the same stand.

The fastest way to destroy a level switch is to put it inside the process.
Aggressive chemistry makes the point better than any brochure. Acids and caustics attack wetted probes. Seals weep. Every vessel pe*******on you add for instrumentation is one more fl**ge to maintain and one more potential leak path to manage.

Microwave beam-break switches take a different approach: stay outside entirely. A transmitter and receiver mount on opposite sides of the vessel and detect whether the beam path between them is made or broken. The beam passes through materials that are transparent to microwave energy like quartz, Teflon, UHMW, fiberglass, and Lexan, so the sensors can work through an existing sightglass or a non-metallic vessel wall. No wetted parts. No coating, corrosion, or probe fouling. External mounting options detect without adding a vessel pe*******on.

Pressure is where this architecture earns its keep. Because the electronics never enter the process, the pressure boundary is the window, not the instrument. High-temperature glass window assemblies for the Microwave 320 are rated to 450 PSI at 70 F, and to 500 F at atmospheric pressure — several times the operating-pressure ceiling typical of microwave switch hardware in this class, where the electronics themselves carry the process rating.

Even better, availability now matches the engineering: we have stocked the key components behind every Microwave 320 build, so lead times across the whole line are shorter — often shorter than the incumbent’s replacement quote when it is time to swap a failing switch.

One practical note for tank owners: the same chemical tanks that need level switching usually carry pressure/vacuum relief. Cognesense covers both sides of that vessel: Shand & Jurs tank safety equipment protects the tank the Microwave 320 is watching.

If a level switch fails in your plant this year, odds are it is a wetted one. Worth asking whether it needed to be wet at all.

False alarms are how chute protection dies. Falling material momentarily blocks the beam, the relay chatters, operators stop trusting the alarm -- and eventually someone bypasses it.

The Microwave 320 separates falling product from a real plug with independent make and break time delays, adjustable from 50 milliseconds to 30 seconds. The relay only speaks when it is sure -- and it speaks twice, through a DPDT output that drives two circuits at once.
