Oval Gear PD
Flowmeters
OG Series
The OG series of oval gear flowmeters work
by using the very low differential pressure generated
across the body to drive a pair of oval gears. This
rotation can be detected by a variety of means to
give either a TTL or contact closure pulse output.
The OG series is available in
a choice of materials and pressure ratings to suit
most applications and as with all positive displacement
flowmeters, the performance improves with increasing
viscosity achieving an accuracy of ± 0.1% of reading.
