FP2000系列是***系列帶***體式 6位數(shù)字顯示屏的經(jīng)濟型葉輪式傳感器。FP2000-R型號是流速指示器，而FP2000-RT型號可指示流速和累計流量。 另外，還提供僅顯示累計流量的FP2000-T。這些裝置使用電池供電，兩節(jié)"AAA"電池可持續(xù)使用長達***年。FP2000具有PVDF葉輪，以及聚丙烯或PVDF管路。

精確測量需要充分發(fā)展的湍流流量剖面。脈動、渦流及液流中的其他擾動將影響精度。雷諾數(shù)大于 4000的流動狀態(tài)將導(dǎo)致充分發(fā)展的湍流。雷諾數(shù)小于2000是層流， 可能導(dǎo)致不準(zhǔn)確的讀數(shù)。

Digital impeller technology with (+2%) accuracy

Integrated 6-digit digital display screen

Provide models of flow rate, cumulative flow rate or flow rate and cumulative flow rate

Suitable for pipe size of 10-51 mm (niche-2"), 0.4-200 GPM

Long-life battery power supply

FP2000 series is a series of economic impeller sensors with integrated 6-digit digital display screen. The FP2000-R model is a flow rate indicator, while the FP2000-RT model can indicate the flow rate and cumulative flow rate. In addition, FP2000-T, which only shows cumulative traffic, is also provided. These devices are powered by batteries, and two AAA batteries can last up to a year. FP2000 has PVDF impeller and polypropylene or PVDF pipeline.

Accurate measurement requires fully developed turbulent flow profiles. Pulsation, eddy current and other disturbances in fluid flow will affect the accuracy. The flow state with Reynolds number greater than 4000 will lead to fully developed turbulence. Reynolds number less than 2000 is laminar flow, which may lead to inaccurate readings.

Reynolds number equation:

Reynolds number=(3160 x Q x G)/(D x V)

Among them:

Q = Fluid velocity in GPM

G = the specific gravity of the fluid

D = Internal diameter in inches

V = Viscosity per centimeter

Minimum straight pipe length requirement

The accuracy of the flowmeter is affected by the interference of pumps, elbows, tees and valves in the flow. Install the flowmeter in a straight pipe as far as possible away from any interference. The distance required for accuracy depends on the type of interference.
