Ultrasonic flow meters offer a wealth of value in the short and long term.

• Large turndown ratio
• No drifting, no periodic calibration required
• No pressure drop
• No restriction in the pipe
• No filters or strainers
• Bi-directional measurement
• No moving parts
• Advanced diagnostics
• Low cost of ownership

One particularly difficult application in refineries is on the furnace feed lines, where ultrasonic technology can add the most value with coker, vacuum distillation and fluid catalytic cracker units measurement.

The simple answer: to ensure product quality, increase safety and control costs. Moisture in trace amounts is a contaminant in liquid feed stocks and must be removed via liquid dryers. Moisture in recycle gas is poison to the catalyst, which promotes acid formation and damages the piping and mechanical infrastructure. Hydrogen enables many refinery processes and controlling its concentration is key. Oxygen (% range) is a key measurement on catalyst regeneration and needs to remain below threshold limits to prevent explosive atmospheres in flare lines and tank farms.

Anywhere you need accurate flow process measurement to save time and money.

• Flare
• NG, Sour Gas, SynGas, Pygas, Ethylene, Propylene, Butene, H2, etc.
• Utilities: N2, Air, Steam
• DCU, VDU, FCCU, etc.
• Water, Liquified Ethylene, LPG, Benzene, Amine, Caustic, Refined Products, Molten Sulfur, etc.
• Custody & Fiscal Oil Measurement, LDS
• Blending Lines

We offer both in-line ultrasonic flow meters, which are highly recommended for heavy residue applications, as well as clamp-on flow meters.

In-line (wetted) ultrasonic meters

• Highest level of performance  
• Permanent measurement (“set and forget”)
• Calibrated for specific applications
• Serviceable under pressure 
• Multi-path diagnostics 

Clamp-on ultrasonic meters

• Economical and flexible Installation  
• Serviceable under pressure
• Can be installed in hard-to-access areas  
• Extremely wide size range
   

Panametrics is the the only ultrasonic flow metering supplier with up to SIL3 safety certification level. Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

The support, advice and training our experts can provide to help you upgrade their systems is just as reliable as our technology. We can help every step of the way, to ensure the highest level of measurement accuracy and safety to avoid risk and get ahead.

• Can measure at process pressure, no need to reduce process pressure with expensive sample system components. 
• Wide dynamic range of sensor, can measure from ppbs right through to ppms, in both gases and hydrocarbon liquids.
• Not affected by background gas changes in composition.
• Up to six (6) measurements can be made with a multichannel analyzer like the moisture.IQ.
• Installed base of thousands and well proven technology in O&G applications.

Here are just a few advantages of using the Panametrics Aurora TDL technology on recycle gas applications:

• Very fast speed of response, giving tighter process control
• No drift technology means no recalibration costs
• Non-contact measurement is immune to corrosive components like HCL in the gas stream

The Panametrics XMTC is a thermal conductivity-based analyzer, perfect for measuring H2 purity in a hydrocarbon background.

Yes, Panametrics works with all the major refinery process licensors.
