FAQs
Frequently Asked Questions
F-300 Product Specifications
- Is the F300 series NSF listed?
Yes, NSF/ANSI 50 - Equipment for Swimming Pools, Spas, Hot Tubs and Other Recreational Water Facilities
Is F300 available with metric LPM scale ranges?Yes, the F-300 is available with LPM flow ranges for metric pipe PN10 OR PN16 in, sizes 32mm, 40mm 50mm 63 mm 75mm 90 mm & 110mm
What models are designed for vertical pipe installations? My pipe size is larger than D & U 300. What can I use instead?The D-300 and the U-300 series is designed for vertical pipe installations. D= Downward flow direction U= Upward flow direction. Available pipe sizes are 1.5" & 2" only. For vertical pipe installations larger than 2", we suggest the appropriate F1000 RB digital paddlewheel flowmeter. This series can be installed on horizontal or vertical pipe.
My meter has a silver 316 ss float. I see the current models have red floats. Are the floats interchangeable between old & new models?The silver float is designed for use in the original F300 which have the GPM and LPM scale flow ranges. The Red float is designed for the new models with sch 40 and sch 80 GPM scales. The floats are not interchangeable.
Can I use the F-300 on pipes other than schedule 40 or schedule 80?Mounting the meter on pipe sizes other than schedule 40 or schedule 80 may result in pitot tube interference or inaccurate readings and is not recommended. The meter's calibration is based on the exact inside diameter of the pipe.
The F-300 can be mounted on metal or plastic pipes with a relatively smooth surface. To operate properly and to prevent leaking, the meter must only be mounted on smooth surface pipes of the specified outside diameter pipe size. The pipe's "schedule" indicates the wall thickness of the pipe and therefore defines the inside diameter and pressure capability.
Models with a suffix letter "P" (example: F-30200P) are calibrated for schedule 40 and schedule 80 metal or plastic U.S. pipe sizes (I.P.S. Iron Pipe Size) only. Models with a suffix letter "M" (example: F-30090M) are calibrated for PN10 and PN (Pressure Nominale) metal or plastic pipe sizes (Metric Pipe Size) only.
What does “pressure and temperature limits are inversely proportional?”This means that as the fluid temperature increases, the maximum pressure capacity decreases by a proportional amount, and as the system pressure increases, the maximum temperature capacity decreases by a proportional amount.
What will my accuracy be if I install the F-300 without the recommended straight length of pipe before and after the meter?The F-300 meter requires a relatively uniform flow velocity profile across the flowing section of pipe. A straight length of pipe before and after the meter is needed to reduce flow profile distortions such as swirl patterns and secondary axial flow patterns caused by elbows, valves, and other types of disturbances. Because these flow patterns will change as the flow rate (velocity) changes, it is impossible to calculate error, and therefore the accuracy of the meter, under these conditions.
