Please read the Instruction Guideline on the next page before installing your flowmeter.
!
This flowmeter is an instrument, special care should be taken when handling and installing.
Inspection of the Flowmeter and Compatibility
!
Carefully inspect the meter for any damage that may have occurred during shipping.
!
Remove the plastic tubing that has been inserted during packaging for shipping reasons.
!
Make sure your pressure, temperature, fluid and other requirements are compatible with the meter before
installation.
!
The maximum temperature capability decreases as the pressure increases. The max PSI decreases as the
temperature increases. See the chart on the following page.
®
!
Although the meter may be suitable for other chemicals, Blue-White meters are tested with water and air
only. If you are unsure of the meters compatibility with your chemical, please consult the factory.
®
!
Blue-White warranties the flowmeter for use with air and water only.

Please use the following steps to guide you through
the installation.
1. The flowmeter must be installed in an exact
vertical plane to ensure accuracy.
2. Use PTFE tape (or similar) on all pipe threads.
Acrylic and other exotic plastics cannot
tolerate PVC Glue and/or pipe dope. Even
fumes can cause crazing. If you are installing
your flowmeter to a glued pipe installation,
install the flowmeter after all glued fittings are
dried and lines are purged of all fumes.
Never hold the meter with pliers or like tools.
DO NOT OVER-TIGHTEN!
3. Wall, floor and ceiling mounts are to be carefully
aligned and sturdy. Wall, floor and ceiling
supports are recommended as needed. This
is to maintain pipe alignment and to prevent
vibration.
4. Valves - Avoid a system that will impose a
sudden burst of flow to the meter. Such a
burst will cause the float to impact the float
stop with destructive force which may damage the flowmeter. Solenoid valves, or other quick
opening valves cannot be used unless meter is protected against sudden bursts of flow. (If
necessary a surge chamber should be installed. This will also be useful in high pressure startup situations) The flowmeter is not warrantied against this type of damage.
5. Maximum working pressure not to exceed recommended psi at fluid temperature (see
Temperature Vs. Pressure chart).
Caution: Follow these steps to avoid failure
Danger: Wear eye protection when installing or
removing the flowmeter.
