Accurately Measure Flow … Right at the Nozzle
Quick and Easy Readings
The aluminum turbine meter lets you monitor your fuel flow with just a quick glance as you fill. An easy-to-read LCD display instantly provides a readout in gallons. Check your batch total or get your cumulative total, all with an accuracy within 5%.
Versatility You Can Count On
This meter can handle kerosene, diesel and biodiesel blends, plus gasoline, including E15 alcohol blends. 1in. NPT threads are standard, with 3/4in. reducer fittings also included to provide additional mounting options.
Easy On, Easy Off
The meter turns on manually or starts automatically with the first trickle of fuel, your choice. For your convenience, it features automatic off — once you stop the flow, the meter shuts off when its job is done. No remembering to hit an off switch, which means no wasted batteries as a result of the meter accidentally being left on.
