The wired 250 L/H Differential Fuel Flow Meter from Mass Flow is adept at measuring the varied fuel consumption in assorted vehicles, given situations where using single-chamber fuel meters would not be feasible. Readouts can be obtained remotely, thanks to its pulse output, such as the on-board controller that features pulse or discrete input in the range of 0 to 32 V.

The fuel flow meter can be used in tandem with fuel monitoring systems or vehicle tracking systems that have been set up on vehicles running the latest Euro 3/4/5 diesel engines. They feature a robust metal moulded case. Thanks to its intuitive design, even if the measuring ring has stopped, the flow meter can still proffer fuel flow.

It can be used effectively on installations that run supply and return fuel lines. It is extremely easy to operate, and can be mounted with ease in any position. It features a fuel filter that is built in.

Since signals are processed digitally, measurements remain precise and work range can be extended significantly. Any hydraulic shocks and vibrations do not impact the fuel flow meter. Further, since it features an extensive clearing section, there is minimal hydraulic resistance in the flow of fluids. Finally, with its brilliant product design, very low consumption of power is assured.
