The DP Series oval gear flowmeters have an outstanding performance especially in oil and fuel, for measuring viscous fluids it is the best type of flowmeter, without a doubt, in the fuel sector since its construction makes the measurement of volume independent of the flow profile, they have very low error and very high repeatability in the measurement. It is a volumetric type meter.

Description of the Oval Gear Flowmeter

Our oval flowmeter consists of two toothed rotors, the machining of these parts is carried out with accuracies of 0.01mm, the higher the precision in the machining there is a lower error due to non-linearity, this instrument transfers a volume determined by mechanical revolution, from the input at the outlet, the volume transferred is practically independent of the flow profile, this added to its reduced size makes it the ideal instrument to be installed in confined spaces.
