Page 4: Product Description
Product description 2.1 Scope of supply 1 Flow meter with mechanical counter. 1 mounting and operating instruction (this manual) 2.2 Flow meter configuration ® The CONTOIL flow meters consist of a hydraulic part, a coupling and an mechanical counter. The hydraulic part determines the nominal size of the flow meter. The flow meters are calibrated before they leave the factory. - Page 5 2.4 Return of materials Never send a device/system back if you are not absolutely certain that all traces of hazardous substances have been removed, e.g. substances which have penetrated crevices or diffused through plastic. Costs incurred for waste disposal and injury (burns, etc.) due to inadequate declara- tion and/or cleaning will be charged to the delivering company or the operator.

Page 6: Installation
Installation CAUTION The surfaces of the device and the medium may be hot. Risk of burns! Carry out work only on cooled systems. Work may only be performed by authorized specialists in accordance with the applicable regulations. Use appropriate protective equipment. WARNING The pipe and the device may be under pressure. - Page 7 3.1 Mounting Flow meter installation Easy access for reading the flow meter and controlling the ancillary equipment is important. Provided that the arrow on the housing is in the direction of flow, the flow meter can be installed in any position without any special modifications. The mechanical counter can be turned to the desired position Exception: upside down installation.
- Page 8 Correct layout of flow meter and accessories If the flow meter is used for viscosities higher than 5 mPa.s, or if it is mounted on the suction side of a pump, the pressure loss and the flow rate that can still be attained should be deter- mined with the help of the pressure loss curves provided in CONTOIL®...

- Page 10 Special requirements - differential measurements For differential measurements, one flow meter is installed in the supply line pipe and one in the return line pipe. The flow difference between these meters determines the consumption. If ordered with the "differential measurement" option, VZOA flow meters are calibrated in ac- cordance with the indicated supply and return flow volumes.

- Page 14 Installing the meter in the pipe Remove the protection plugs or caps from the flow meter (inlet and outlet). Insert the flow meter into the pipeline in the prescribed position and flow direction. The arrow on the flow meter should correspond with the direction of flow. Install mating flanges parallel and without tension in the pipe.

Page 17: Maintenance And Repair
Maintenance and Repair 5.1 Calibration All our flow meters are calibrated in the factory. An accuracy check and recalibration is offered at Aquametro Oil & Marine AG, this is usually dependent on customer, operator or regulation requirements. This interval depends largly on the operating conditins, process liquid and the application the flow meter is installed in. - Page 18 Before working on the hydraulics: put the system or section out of operation close the stop valves release the pressure put a suitable tray underneath the connection to be worked on be prepared for spillage, have absorbent at hand Cleaning of flow meter: ...
