Series OV - Heavy Duty - Loading meter
The OV series of meters was specially developed for use in filling tank trucks and rail tank cars. The sizes and the selection of material are adjusted to the requirements of modern filling systems for mineral oil products such as gasoline, aircraft fuel, diesel and heating oil. The meters are suited for both top loading and bottom loading systems.
The filling meter contains, except for the oval wheels and the slotted disk of the pulse pick-up AG54, no moving parts. The meter was designed as a pure volume transmitter and, therefore, a local display is not planned. Due to ist large measuring chamber volume and therfor low number of revolutions, it has a large service life reserve.
The filling meters of the OV series have a new type of pulse trigger with two independent pickups. These insure the strict proportionality between the partial volumes measured and the volume pulse, without the previously used uniform motion gear unit. Periodical errors, which are system based, do not occur.
The use of two independently functioning pulse pickups (90° phase shifted) insures not only the redundancy required for transactions, which require calibration, but this also allows a serially connected electronic device to identify and monitor return flow.
