The FP2000 Series is designed to measure the flow of a fluid in a pipe. The meter is factory calibrated
to any engineering units and displays the rate of flow, total or both (depending on the model selected)
on a 6-digit LCD display. Two “AAA” batteries power the unit for up to one year. There are three models
available: FP2000-R is a rate meter designed to measure and display the rate of flow; FP2000-T is a
totalizer meter designed to measure and display the total flow; FP2000-RT is a rate/totalizer meter
designed to measure and display both the rate of flow and the total flow.
Measuring accuracy requires a fully developed turbulent flow profile. Pulsating, swirling and other
disruptions in the flow stream will affect accuracy. Flow conditions with a Reynolds Number greater
than 4000 will result in a fully developed turbulent flow. A Reynolds Number less than 2000 is
laminar flow and may result in inaccurate readings.
Reynolds Number Equation:
Reynolds Number=(3160 x Q x G)/(D x V)
Where:
Q = Flow rate of the fluid in GPM
G = Specific gravity of the fluid
D = Pipe inside diameter in inches
V = Fluid viscocity in centepoise
Minimum Straight Pipe Length Requirements
| The meter’s accuracy is affected by disturbances such as pumps, elbows, tees, valves, etc., in the
flow stream. Install the meter in a straight run of pipe as far as possible from any disturbances. The
distance required for accuracy will depend on the type of disturbance. |
