Liquid meters with oval gears PPO-40/0.6 SU are designed to measure the volume amount of non-aggressive petroleum products and have an accuracy class of 0.25 or 0.5.
The principle of operation of the PPO-40/0.6 SU meters with oval gears is that two oval-shaped gears, rotating under the action of a liquid flow and being engaged, measure a certain volume of liquid at each revolution. The rotation of the gears is transmitted to the counting mechanism, being converted into units of volume.
A coarse or fine filter must be installed in front of the CJ-PPO 40/0.6SU counter
