The BeerFlow® meter, with a keg coupler screwing on below and a beer line screwing on above.
Ultrasonic keg meter
No drop wasted.
Revolutionised stock counting & waste management.BeerFlow® fits between the keg coupler and the beer line and shows exactly how much beer is left, as you pour.
Venues lose thousands in revenue every year on beer they can't account for.
Line faults, over-pouring, theft and training gaps all show up the same way at stocktake: a keg that ran dry sooner than it should have.
Dipping and weighing kegs can't tell you where it went. With costs rising and beer prices under pressure, every drop needs to be accounted for.
How it works
Sits between the coupler and the line.
BeerFlow® uses ultrasonic flow measurement to track every drop leaving the keg, and shows what's left in real time on its own display.
01
Fit it
Screw BeerFlow® onto the top of the keg coupler, then screw the beer line onto the meter. No engineer required.
02
Calibrate it
Run a quick calibration in the BeerFlow® app over Bluetooth. Set it once and it stays accurate for the life of the meter.
03
Count every keg
The display shows what's left as you pour. Press Reset when you change the keg and it starts again from full.
The result
Profitability's secret ingredient.
Quick, accurate counts
Seconds, not hours
Read what's left in every keg at a glance. No weighing, no dipping, no guesswork at stocktake.
True accountability
Trusted results
Finally, a tool that delivers accurate results. Every keg is counted to the drop, so the numbers you act on are numbers you can trust.

Our story
Built by people who've counted the kegs.
BeerFlow® was founded by two close friends and hospitality professionals who'd had enough of counting beer with slow, inaccurate tools.
The problem was never the beer.
As hospitality professionals, Luke and Harry had to count their beer with tools that were archaic and inaccurate. The new products on offer were quick fixes: expensive line-cleaning machinery and endless perfect-serve training programmes.
The real reason venues lose thousands in revenue every year is a lack of accurate data and accountability. With costs rising sharply and beer prices becoming unsustainable, it has never mattered more for hospitality businesses to control every penny.
After years of experimenting with new technologies, they found that ultrasonic flow meters could count beer with real accuracy. Working with their manufacturer, they built the BeerFlow® meter.
Developed with a leading ultrasonic flow meter manufacturer whose past projects include work with NASA.

Summary
BeerFlow® at a glance.
01 · The problem
£212 million of draught beer revenue is lost in the UK every year. The only widely used competitor, the Kegcheck, is inaccurate and not trusted by operators. The problem is industry-wide and currently has no adequate solution.
02 · The solution
BeerFlow® is an ultrasonic flowmeter that attaches to any keg coupler and monitors every drop dispensed in real time. It delivers stock counts to under 2% variance, with no engineer installation required and a three-year battery life.
03 · Unit economics
Sales price £95 (inc. VAT) · Gross profit £40 per unit · 42% gross margin. A three-year product lifecycle creates a strong recurring revenue profile across the installed base.
04 · The market
Approximately 460,000 beer lines are in use within UK hospitality. The seven largest pub companies (31% of the market) provide a total addressable market of £13.7 million. BeerFlow® is designed for the global market from launch, with expansion into the USA, Canada and Australia planned first.
05 · The team
Co-founders Luke Coughlan and Harry Stirland bring over 30 years of combined hospitality operations experience, supported by an advisory board of a senior strategic finance advisor and a commercial barrister.

The problem
Four reasons the waste stays hidden.
Theft and poor practice
When no one can measure exactly how much beer has been poured, free pints for friends, drinks that never go through the till, over-pouring and outright theft all disappear into the margin of error. If the counts can’t be trusted, managers can’t tell a real loss from a bad count, so nothing gets fixed.
Inaccurate counts
Stock results are only as good as the counts that go into them. When keg levels are guessed or misread, the final report looks believable but is wrong, so operators chase problems that aren’t there and miss the ones that are.
Team
Stock is often counted by whoever is on shift, and everyone reads a keg differently. With different people estimating each week, results swing from count to count, making it impossible to see a real trend or trust any single number.
The solution
Account for every drop of beer.
BeerFlow® ultrasonic flowmeter monitors the volume of liquid dispensed from a keg. It shows, in real time, the remaining amount of product for stock counting, so the operator can record and account for every drop of beer.
By radically increasing the accuracy of stock management, it helps pinpoint every waste issue, from equipment faults and theft to training, so venues keep the optimal yield from their products.
Easy install
Screws on between the coupler and the beer line. No engineer installation required.
<2% variance
Automatic counting of every pour, so stock figures can finally be trusted.
Bluetooth calibration
User-friendly calibration through the BeerFlow® app over Bluetooth.
Instant ROI
An immediate increase in profits for our customers.
Competitive landscape
How BeerFlow® stacks up.
The Kegcheck is in almost every cellar, but it’s slow, depends on the environment and invites user error. The Digiten meter shows no defined unit, needs mains power, has no environmental protection and uses a turbine, not ultrasonic.

Our take
Too much, too technical.
Most operators don’t need a dozen variables, POS integrations and an installer. They need to know exactly where their beer is going.
BeerFlow® does just that: it fits onto any keg coupler with no engineer installation and counts every pint, keg by keg.
Testing
Proven accurate on draught.
Working with our manufacturer, we tested their existing ultrasonic water flow meters in a new application: measuring draught beer. They proved highly accurate: after a simple calibration using just over a pint of product, they measured every pour to within 2% (over 98% accuracy).
Our R&D now turns that proven technology into a product built for the cellar: smaller, lighter flow meters in a more compact body that fits neatly between the keg coupler and the beer line.

* The big 7 UK pub companies
Go-to-market strategy
Land the big 7, then expand.
Phase 1
Secure contracts with the 7 largest pub companies in the UK (the big 7), who own 31% of the pub market.
The big 7: 31%
Other pubs: 69%
Phase 2
Trade shows, networking events and other opportunities, as our sales team targets the rest of the UK market.
The big 7: 10%
Other pubs: 22.2%
Other hospitality: 67.9%
Phase 3
BeerFlow® goes international, targeting the USA, Canada and Australia first.
Expansion
From meter to platform.
Our ambition is to become a global cellar solutions company.
BeerFlow® WIFI
Integrate WIFI compatibility so users can check product wherever and whenever they want.
Build our own stock management software, compatible with POS systems, to monitor pours in real time, detect pours made without transactions and provide micro yield data on team members.
BeerFlow® Fonts
Build our own beer fonts with integrated ultrasonic flow meters. These will be mains powered and much more likely to be in range of WIFI than the cellar.
Making the use of the software even more possible.
Global cellar solutions
Cellar engineer and beer tech jobs are going unfilled, while the equipment operators rely on, from coolers to fonts to beer engines, is over-engineered and too complicated to look after themselves.
We plan to grow BeerFlow® into a global cellar solutions company, building simpler, user-friendly equipment that operators can fit, run and maintain without calling out an engineer.
