FloScan's proprietary DataLog Fuel Monitoring Software now has built in Geo-Fencing capabilities that automatically track fuel used when travelling through an unlimited number of geographic areas. DataLog was primarily developed to provide minute by minute tracking of a vessel's fuel consumption broken down by propulsion and non-propulsion engines and now Geo-fencing enables synchronising of geographic zones with various tax rates and regulatory authorities. The DataLog Fuel Monitoring software is included at no-charge with every FloNET Fuel Monitoring System.



This information is provided by onboard FloScan fuel flow sensors on the vessel's engines and positional information is derived by linking the FloNET NMEA 2000 hub to the vessel's GPS system. The data is collected and cataloged by DataLog in a spreadsheet format that allows the fleet system administrator to easily incorporate geographical triggers so when the vessel enters one predefined boundary the program will record propulsion fuel consumption on a minute by minute basis until it exits that area and crosses into the next predefined area.





FloScan Instrument Company, Inc is pleased to announce that their new Series K Stainless Steel Flowmeters have obtained ABS Product Design Certification. This certification permits the installation of FloScan Fuel Monitoring Systems on ABS-classed vesels which require steel piping components.PDA Certificate Number 13-HS1050296-PDA

FloScan is the world's leading manufacturer of Fuel Monitoring Systems for permanent installation on diesel and gasoline engines.  FloScan Systems are installed worldwide on commercial and recreational vessels, stationary industrial generators and general aviation aircraft... everywhere internal combustion engines are used.  Since FloScan flowmeters were first introduced in aircraft 40 years ago, more than 750,000 FloScan sensors and systems have found their way onto almost every make of gasoline and diesel engine in the world rated from 25hp to 6000hp. 

What makes our turbine flowmeter design superior to others is the internal fuel bypass feature which makes it immune to fuel blockage.  This "Fail-Open" design eliminates the costly addition of a fuel bypass line required by oval gear positive displacement flowmeter manufacturers to address this issue.  On critical engine applications such as a marine propulsion engine, industrial power generator or aircraft application, fuel blockage can have disastrous consequences.  Whatever your fuel measurement needs, FloScan provides the most economical and safest solution on the market.

FloScan Fuel Computers show exactly how much fuel you've used, and how fast you're using it. Rather than trying to measure what's splashing around in your tanks, FloScan's electronic sensors determine fuel flow right at your engine. And the computerised display indicates precise consumption totals. There's no guesswork. Unlike fluctuating fuel tank float gauges, you receive immediate, accurate data. No matter how rough the seas no matter how many tanks or engines in your boat.


A FloScan Fuel Computer pays for itself in fuel savings alone. You can easily set your boat's most efficient speed by watching your FloScan to see how fuel usage varies at different speeds and running conditions. Most skippers can save 10%-20% on their fuel bill, so the serious fisherman/cruise can pay for his FloScan in less than a season. Something else to consider: a FloScan Fuel Computer will eliminate the need for a tow if you run out of fuel. (Think of it as an insurance policy with an automatic dividend of more fishing and real dollar savings).
Adventure without misadventure.
How many times have you hesitated to try new grounds or stay out longer because you couldn't trust your fuel tank gauges? FloScan Fuel Computers are a remarkable tool that'll give you more fishing and greater range with no fuel worries, plus, it pays for itself.


A FloScan Fuel Computer serves as a watchdog on engine performance. For example, if your LPH or LPNM increases from what you've already determined to be a efficient operating level, you'll know something's amiss - nicked prop, fouled hull, engine problem, etc. Even something as simple as a defective spark plug can up your fuel consumption by 20-40%, without any other noticeable change in engine operation.


FloScan Flow Sensors are fail-safe. With the same opto-electronic technology used by the safety-driven aviation industry (FloScan's are virtually the only fuel flow sensors given FAA approval for use in general aviation aircraft), our fuel computers have a scant margin of error of less than 2% with on-board calibration. Tough, durable components like sapphire rotor bearings, precision aluminium die-castings, and gold-plated detectors perform in seas nasty enough to drive barracudas below decks.


FloScan has a model for just about every petrol engine built, from single outboards to high-performance inboards. And our diesel models are the first affordable diesel fuel monitoring systems in the marine world, priced about 75% less than any comparable competitive product. We'll match the system to your engine. All we need is your engine make, model number, and hp rating.


We've been connected to some well-known engines. FloScan is the world's #1 producer of fuel flow sensor systems - over 500,000 used on cars, trucks, boats, and airplanes. (As a matter of fact, we invented them for each of these industries).


There are more than 100,000 FloScan sensors aboard such aircraft as Cessna, Piper, and Beechcraft, and such trucks as Kenworth, Peterbilt, Freightliner, and International. Remember in 1986, the record-breaking, non-stop, around-the-world flight of the "Voyager'" in which error-free fuel monitoring was absolutely paramount to the mission? Pilots Yeager and Rutan were guided by FloScan fuel flow meters. We'll give you the same security at sea. No matter where you’re fishing or cruising, FloScan can extend your range and give you peace of mind - with an instrument that pays for itself.
