Page 4: Regulation Use
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. -
Page 5: Operating Principle
4. Operating Principle The OVZ oval wheel meter is a positive- displacement flowmeter. The measuring element comprises two toothed precision oval gearwheels, which are driven by the liquid inlet pressure. As the liquid rotates the gears, a fixed quantity of liquid is transported through the chambers for every turn of the oval-wheel pair. -

6. Mechanical Connection Before installation: • Make sure that the actual flow rate corresponds with the measuring range of the meter. • Make sure that the approved maximum operating pressure and operating temperature of the meter are not exceeded. • Remove all transport restraints and ensure that there are no pieces of packaging left in the meter. -
Page 7: Electrical Connection
7. Electrical Connection 7.1. General Important! Make sure that the voltages in your plant correspond with the voltages on the nameplate. • Make sure that the electrical supply lines are dead. • Meters with connectors: solder the ends of the connection cable according to the wiring diagram in the accompanying portable socket-outlets. -
Page 8: Mechanical Operation
8. Mechanical Operation • To avoid pressure peaks, the flow medium should flow slowly into the meter. Important! Pressure peaks arising from a sudden influx of liquid, caused by solenoid valves, ball valves etc, may seriously damage the meter (water hammer!). Ensure that the sensor is always filled with medium when in the operating state. -

Page 10: Maintenance
10. Maintenance The meter requires no maintenance if the measured medium is not contaminated. Should it be necessary to clean the meter, the case cover can be easily removed to gain access to, and clean, the inside of the case (see Sec. 11. Dismantling / Installation). -
Page 11: Dismantling / Installation
11. Dismantling / Installation Dismantling: • Drain piping. • Loosen cover screws and remove cover and O-ring. • Mark the position of the gearwheels relative to one another with a pencil. • Remove the pair of oval gearwheels and clean parts with care; do not scratch the sealing faces. -
