3. Regulation Use
The model OVZ is an oval gear, positive displacement flowmeter which can be
used to measure and monitor the flowrate of viscous liquid (min. 10 mm²/s to
max. 800 mm²/s); (max. viscosity 1000 mm²/s upon request). Only measure
clean, non-abrasive liquids with adequate lubricating properties, and against
which the materials used in the sensor case are chemically resistant. Ferrite
particles may become deposited on the oval gears as they do contain permanent
magnets, - thus causing maloperation, or destruction of the oval wheel. We
recommend our model MF-RI... magnetic filter if the liquid contains a high
concentration of ferrous solids. In case of uncertainty, please consult your
supplier.
