The compact and light weight fuel flow meters for monitoring fuel consumption, differential type
FUEL-VIEW flow meters 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 contamination and can be removed and washed without disassembling the flow meter.
FUEL-VIEW model DFM-500D-K can be used for 10...500 l/h. It is a differential fuel flow meters with a separate input and output connection for the supply and return line to measure the consumption of the fuel. The instrument has a cable for pulse output (with external power).
