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
SPECIFICATIONS
Max Working Pressure: 20 bar (300 psi) at 21°C (70°F)
Max Fluid Temperature: 93°C (200°F) at 0 psi
Max Ambient Temperature: -10 to 43°C (14 to 110°F)
Full Scale Accuracy: ±2%
Power Requirement: 2 "AAA" batteries (included)
Enclosure: NEMA 4X (IP56)
Maximum Pressure Drop: 0.6 BAR (8 psi) (varies per model)
Approximate Shipping Wt: 0.91 kg (2 lb)
Materials of Construction
Pipe Fitting: Polypropylene (FP2000 series) or PVDF (FP2100 series)
Sensor, Paddlewheel, Axle: PVDF
Sensor O-ring seals: FKM
Enclosure: ABS

| 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. |

Excellent stand alone flow-meter
I have used several of these units to monitor seawater flow in experiments we conduct in a marine laboratory. I have been very pleased with their operation. I especially like that they are battery powered. There is only one issue that I have had, the plastic rod that holds the propeller has broken on several of these units and I can not get replacement parts. I fortunately was able to replace it with a stainless steel tubing, which is much more durable. This would not work if the media being monitored was acidic or basic.
