FP2000系列是一系列帶一體式 6位數(shù)字顯示屏的經(jīng)濟(jì)型葉輪式傳感器。FP2000-R型號(hào)是流速指示器，而FP2000-RT型號(hào)可指示流速和累計(jì)流量。 另外，還提供僅顯示累計(jì)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(zhǎng)達(dá)一年。FP2000具有PVDF葉輪，以及聚丙烯或PVDF管路。

精確測(cè)量需要充分發(fā)展的湍流流量剖面。脈動(dòng)、渦流及液流中的其他擾動(dòng)將影響精度。雷諾數(shù)大于 4000的流動(dòng)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)。

雷諾數(shù)方程:

    雷諾數(shù) =(3160 x Q x G)/(D x V)

    其中:

    Q=單位為GPM的流體流速

    G=流體的比重

    D=單位為英寸的管內(nèi)徑

    V=單位為厘泊的流體粘度

最低直管長(zhǎng)度要求

該流量計(jì)的精度受液流中泵、彎管、三通管、閥門(mén) 等的干擾影響。盡量將該流量計(jì)遠(yuǎn)離任何干擾安裝 在直管中。精度所要求的距離取決于干擾類(lèi)型。

FTB-1306A_FTB-1307_FTB-1308_FTB-1311_FTB-1312渦輪流量計(jì)OMEGA

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

Low pressure drop design

Provide polypropylene or PVDF piping

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.
