Oval Gear Flowmeter - Series LOGF

LARGE CAPACITY FLOWMETERS

Fluidex series LOGFFLUIDEX series LOGF series is a Positive Displacement Flow Meter with large capacities covering flow rates up to 2500 LPM (660 US GPM). The meters are available in DN80 and DN100 (3" and 4") lines sizes. The LOGF has two rotating gears with oval shape. A fixed amount of the liquid passes between the gear teeth and through the meter after each revolution. The flow rate is identified by the number of shaft rotations. Registers can either be mechanical or electronic with ex-proof or Intrinsically Safe models. The LOGF is used in a wide range of applications including -but not limited to- loading, un-loading & distribution management of petroleum products, marine, aviation & many industrial facilities.
