• Turn off any associated pumps to reduce line pressure and slowly fill the line and meter with fluid before restarting pumps .
Doing so reduces the possibility of meter damage caused by errant air pressures in the line and meter .
• Make sure all pipe conforms to the same pressure output rating as the pump .
• Make sure to apply thread sealant to all pipe threads .
• Make sure to install the meter as shown in

Please check all connections to leakage . After the installation, we recommend doing several transactions into an approved
tank . Should the use of different oil viscosities show discrepancies by the error limit, this can immediately be corrected at the
site . This avoids the need to remove or exchange the meter . In case of pretested meters, corrections can be carried out by
technicians or officials of the National Weights and Measure Laboratory .
