Page 4: General Description
GENERAL DESCRIPTION The Blancett B1750 positive displacement gear flow meters are similar in design to the gear pump. The principle of operation is reversed; instead of the gears driving the medium, the medium drives the gears. A non-intrusive magnetic pick-up or hall-effect... - Page 5 Figure 1 Install the meter upstream from control valves and fluid regulators if possible. See Figure 1. Back pressure from control valving is beneficial for stable running. Eliminate all dirt, debris and metal shavings from the piping as the liquid must be free from any particles larger than allowed by the manufacturer’s specifications.
- Page 6 Maintenance Guides are provided with the meter and are also available from the factory. These should always be reviewed by personnel prior to attempting any maintenance work. overwhelming majority of downtime and repairs are the result of breakages due to improper maintenance actions, lack of training or rough handling.
- Page 7 contaminants, then filtering should be installed. If plugging is repeatedly caused by particle build up, then review the cleaning and maintenance procedures in the following section. Because of the vast differences in fluid types and in-plant procedures, there may be some trial and error involved in determining the ideal flushing or cleaning regimen.

Page 8: Flow Meter Guidelines For Paint Operations
FLOW METER GUIDELINES FOR PAINT OPERATIONS Before installing, operating or attempting maintenance on a flow meter read the appropriate Maintenance Guide. As with any precision engineered device, the equipment should always be operated and maintained in accordance with the manufacturer’s instructions. - Page 9 maintaining a flush procedure which keeps the meter internals clean and wet is critical to optimum performance and minimum maintenance. Cleaning cycles will vary due to differences in coatings, equipment and cleaning fluids used. Some testing may be prudent to determine the most efficient method. Cleaning cycles using DI water only may require more flushing than those using additives due to the superior cutting ability of solvents.

Page 10: Typical Automated Cleaning Cycle
TYPICAL AUTOMATED CLEANING CYCLE At the beginning of the cleaning cycle, clean with DI water for a significant period of time before introducing any air at all into the system. For example, the first thing the meter should see after push out is a relatively long blast of solvent or DI water for at least 3 seconds or more depending on the coating. - Page 11 FLOW METER GUIDELINES FOR PAINT OPERATIONS Leave flushing solvent in the lines overnight or during extended off-times. This keeps internals wet, preventing residual paint from drying and helping start ups. Follow the Maintenance Guide instructions when opening and cleaning a meter. During cleaning, separate the gears from the shafts.

Page 12: Calibrations
DON’T: Dry paint lines using pressurized air. Flow meters are designed to flow liquids. Meters should be closed to air except when air is part of an automated purge cycle. Do not dry lines after purging. DON’T: Allow materials to dry inside the meter. When a meter is removed from the line during maintenance, internals... - Page 13 A Blancett display may be used in totalizer mode provided the KFT is set to count each pulse (KFT = 10000). Trigger at least 500ml of your sample fluid, in a steady stream, at approximately the desired flow rate, into a graduated beaker.
