These rugged, high accuracy positive displacement flow meters offer
excellent performance over a wide operating range. Linearities
of ±0.25% are easily achieved with common fluids such
as engine oil and flow ranges of 200:1 are achievable with
a 30 cSt oil. A choice of materials, 316 stainless steel,
aluminium, PEEK™ or even Hastalloy C allows the meters
to be used in a variety of corrosive applications.
The oval gear PD meter uses two fine-toothed meshed gears
that are oval in shape and engage each other in a precision
machined body. They rotate in opposite directions trapping
two crescent-shaped pockets of fluid between themselves
and the housing. This fluid is transferred sequentially
from the inlet to the outlet and two or more pulses are
transmitted for each revolution of the gear. Detection is
either a reed switch or a Hall effect sensor.
