Installation

What’s in the Box 

The F-550 flow Meter is shipped with the following contents: 

• F-550 Flow Meter (flowmeter may ship with plastic tube insert to prevent damage during shipping, remove plastic tube before installation) 
• Quick Start Guide (QSG) 

Preparation 

• Remove the Flow Meter from the box. Ensure the meter, float, and guide rod are intact. Confirm flow meter is proper for your pipe size and flow. 
• Identify the proper location for installation. The flow meter must be vertical and properly mounted/supported. The location should be in an area that allows easy reading of the meter.  

Piping and Physical Installation 

STEP 1. Unpack the flow meter

• Check for damage while unpacking the flow meter. 
• Be sure the meter is suitable for your application. 
• Check maximum temperature and pressure. 
• Although the meter may be suitable for other chemicals, Blue-White meters are tested with water only. If you are unsure of the meter’s compatibility with your chemical, consult the factory. 
• Blue-White guarantees the meter is suitable with water only. 

STEP 2. Choose a suitable location for the flow meter

• Never allow the flow meter to support the weight of related pipe or tubing. 
• Flow meter must be installed in plumbing which is free of vibration. 
• Flow meter must be installed in an exact vertical plane to ensure accuracy. 
• Valves – Avoid a system that will impose a sudden burst of flow (water hammer) to the meter. Such a burst will cause the float to impact the float stop with destructive force. Magnetic, solenoid, ball, or other quick-opening valves cannot be used unless the meter is protected against sudden bursts of flow. 
• Do not exceed maximum working pressure (see Temperature vs. Pressure chart). 

STEP 3. Connecting the flow meter to the plumbing

• Use an appropriate amount of PTFE (or similar) tape on external pipe threads before making connections. 
• Acrylic and other exotic plastics cannot tolerate PVC Glue and/or pipe dope. Even fumes can cause crazing. If you are installing your flow meter to a glued pipe configuration, install flowmeter after all glued fittings are dried and lines are purged of all fumes. 
• Install the meter to the panel using the panel lock nuts. Do not over-tighten. 
• The meter adapters are provided with wrench flats. Prevent the meter adapters from rotating while attaching the inlet and outlet plumbing. Be careful not to damage the plastic threads. 
• Maximum panel thickness:  

1/2” (13 mm) for F-55250, F-55375, F-55376, F-55500 

13/16” (21 mm) for F-55750, F-55010, F-55015, F-55200
