The compact and light weight fuel flow meter for monitoring fuel consumption
> IntroductionMass Flow ONLINE B.V., sells flow measuring and controlling products through the internet. From the website www.massflow-online.com flow meters or controllers can be ordered 24 hours a day 7 days a week. Most products are on stock and will be shipped world wide within two working days.
> DescriptionThe new FUEL-VIEW series of flow meters offer a compact, light weight and very cost-effective solution for measuring fuel consumption and operating time of vehicles, tractors, river vessels or any mobile or fixed installations with diesel engines. Its unique features for protecting and preventing theft of fuel, the protection against overstatement of readings and intervention and the patented method of measuring different engine operating times makes FUEL-VIEW the best solution on the market today. The FUEL-VIEW offers a local display and has several secure onboard counters that can be operated via the selector magnet as supplied rather than by user contact.
> FUEL-VIEW seriesThe FUEL-VIEW series operate on the principle of a rotary piston that is mounted into a chamber ring which rotates in a chamber case. The rotating speed is measured by electronic sensors which measure a magnetic pulse. The number of pulses in time is proportional to the fuel flow rate. The unique design of the flow meter allows fuel flow, even if the chamber is locked or clogged up. A fuel filter effectively protects the measuring chamber from con-tamination and can be removed and washed without disassembling the flow meter. FUEL-VIEW flow meters can be supplied in full scale ranges from 50 l/h up to 500 l/h with the stan-dard configuration being a blind meter together with a signal cable. As an option, a battery powered LCD display allows reading of actu-al flow [l/h], total flow consumption [l], total engine operating time [h], engine operating time in ”idling”, “optimal” and “overload” mode. Additionally to the single chamber FUEL-VIEW models there are differential models available. These meters have a separate input and output connection for the supply and return line to measure the consumption of the fuel.

Interference security method
Blowing with air Tampering mode is to protect from tampering with the
purpose to increase fuel consumption metering (for
example by blowing air). Tampering usually causes sharp
increase in fuel consumption exceeding maximum. DFM
electronic board registers increased fuel consumption
while the fuel meter work suspends, and tampering meter
activates which registers the volume of fuel flown through
the fuel meter at higher speed.
Magnetic field Special reed switch is activated when exposed to static
interference magnetic field interference for more than 5 seconds and
the time of interference is counted by “interference time”
counter.
Supply power Embedded battery supplies autonomous operation of the
switched off flowmeter up to 2 years.
Disconnection from Installation kit elements have openings for sealing.
