3.0 Installation
3.1 Installation Requirements
Before beginning installation, review your system flow and pressure to ensure your F-451 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. · Don not install in direct sunlight. · 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 location where pipe will be full at all times.

3.2 Tools Required

·

PTFE Tape

·

Level

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

8

F-451
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 factory for assistance.
3.3 Installation Instructions
1. The flow meter must be installed in a vertical plane to ensure accuracy. Misalignment may damage the flow meter and also may cause the o-ring seals to leak. The meterbody material can be damaged by UV rays. Do not install in direct sunlight.
2. Use only PTFE tape on the threaded adapters. Pipe dope and glue will damage the meter body and fittings. Or install the flow meter after all glued fittings have dried and fumes have been purged from the system. Never hold the meter body with pliers or like tools. Union nuts should be hand tightened only. DO NOT OVER-TIGHTEN!
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 will damage the meter. Such a burst will cause the float to impact 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. (see temperature VS pressure chart)

F-451
3.4 Polycarbonate Shield Installation Instructions Use these instructions if you have purchased the optional Polycarbonate Shield Kit, KIT-SHS.
1. Unpack the KIT-SHS. The kit includes shield and two adapter rings. Ensure all components are present and in good shape. The flow meter must be dis- assembled to install the shield.
2. Unscrew top union nut and remove. Place meter on flat surface. 3. Snap shield adapter rings onto union nuts. One adapter ring will
need to slide over the meter body and onto bottom union nut. 4. Keep top meter adapter, O-ring, wire holder, guide rod in place if using
in-line flow meter. It using elbow adapters, it will be necessary to remove top adapter when placing shield.

10

5. Place shield over the meter body and onto the adapter ring.
6. With the top adapter in place, put other union nut / adapter ring onto top of meter body and shield. (Be sure shield fits into adapter rings properly without bending)
7. Hand tighten union nuts. The flow meter is ready for service.

4.0 Reading your F-451 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 float at top.
5.0 Maintenance and Troubleshooting
· The F-451 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 of the process pump or valve and remove any pressure from the piping. If isolation valves are installed, shut these to minimize the amount of water that may leak. Locate nearest unions on piping to allow for removal of flow meter. The F-451 Flow Meter may also be removed by unscrewing the flow meter union nuts. Remove the flow meter and clean any debris in the flow meter. Use 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 flow meter requires NIST Calibration Certification, please contact the factory for this service.
