Application Notes

While meters may be suitable for other chemicals, Blue-White cannot guarantee their suitability. It is the responsibility of the user to determine the suitability of the flow meter in their application. Flow meters are tested and calibrated for water only.

Ordering Information / Model Number Matrix

The F-410 Model Number is constructed as follows:

F (Flow Meter) - 40750 (1-10 gpm / 4-38 lpm, 316SS Float) or 41000 (2-20 gpm / 8-80 lpm, 316SS Float) - LN (316 Stainless steel rod Guide-Wire Material) - 12 (.75" Female NPT, Polypropylene Adapter) or 16 (1.0" Female NPT, Polypropylene Adapter) - (Blank) (Viton O-Rings) or -22P (EP O-Rings).

Example Model Number: F-40750LN-12

Note: In-house NIST Calibration, silicone oil-free, and bulk packaging options are also available.

Materials of Construction

Temperature vs. Pressure Graph

The 'Maximum Temperature vs. Pressure' graph illustrates the relationship between static pressure and the maximum allowable fluid temperature. It shows a downward trend, indicating that as pressure increases, the maximum safe operating temperature decreases. Specifically, at 0 PSI (0 bar), the maximum temperature is 150°F (88°C), while at 150 PSI (10 bar), it drops to 70°F (21°C).

Installation

Installation Requirements

Before beginning installation, review your system flow and pressure to ensure your F-410 is proper for your system parameters.

Pipe Requirements:

• The flow meter is designed to work best when installed in a perfectly vertical pipe system.
• Ensure piping design prevents any stress on the meter fittings, minimizes vibration, and ensures location with direct visibility and minimal possibility of damage from forcible contact.
• Pipe should be clean and free of debris.
• Connecting pipe should be uniform and not warped.
• Pipe must be properly supported even during maximum water flow conditions.
• Use of unionized fittings before and after the flow meter will allow for easier installation and removal for maintenance.
• On/Off solenoid valves and pumps installed before the flow meter should be accompanied by flow regulating/throttling valves, or similar device, to prevent sudden and forcible flows through the flow meter, which can cause damage to flow meter components.
• Choose a location where the pipe will be full at all times.

Tools Required

• PTFE Tape
• Level

Note: Keep flow meter away from pipe glue fumes. Ensure all pipe glue is dry before installing the flow meter. Pipe glue solvents will damage acrylic.

Installation Instructions

Safety Warning: Always wear protective clothing, face shield, safety glasses, and gloves when working on your equipment. Use caution when lifting and mounting equipment. When in doubt, contact the factory for assistance.

1. The flow meter must be installed in a vertical plane to ensure accuracy. Prepare piping and components per standard piping installation.
2. Use only PTFE tape on the threaded adapters. Pipe dope and glue will damage the meter body and fittings. Alternatively, install the flow meter after all glued fittings have dried and fumes have been purged from the system.
3. Mounts and supports must be sturdy enough to support the plumbing and prevent vibration. Vibration and heavy loads will damage the meter.
4. Avoid imposing a sudden burst of flow to the meter. Solenoid valves can cause such bursts, which will impact the float against the top float stop with destructive force.
5. The maximum fluid temperature is dependent on the working pressure. High pressure and temperature will damage the meter (refer to the temperature vs. pressure chart).

Reading your F-410 Flow Meter

Avoid imposing a sudden burst of flow to the meter. Solenoid valves may cause the float to impact the top float stop with destructive force. Always read the float at its top position.

Maintenance and Troubleshooting

The F-410 Flow Meter requires very little maintenance. However, the flow meter may become clogged due to excess debris in the water. If this happens, simply shut off the process pump or valve and remove any pressure from the piping. If isolation valves are installed, shut these to minimize water leakage. Locate the nearest unions on the piping to allow for removal of the flow meter. Remove the flow meter and clean any debris using mild soap and a soft bristle brush.

Reinstall the flow meter and test. If the float was removed during the cleaning process, ensure the float was reinstalled properly. The float is wider at the top.

If the flow meter requires NIST Calibration Certification, please contact the factory for this service.
