FP2000系列是一系列带一体式 6位数字显示屏的经济型叶轮式传感器。FP2000-R型号是流速指示器，而FP2000-RT型号可指示流速和累计流量。 另外，还提供仅显示累计流量的FP2000-T。这些装置使用电池供电，两节"AAA"电池可持续使用长达一年。FP2000具有PVDF叶轮，以及聚丙烯或PVDF管路。

精确测量需要充分发展的湍流流量剖面。脉动、涡流及液流中的其他扰动将影响精度。雷诺数大于 4000的流动状态将导致充分发展的湍流。雷诺数小于2000是层流， 可能导致不准确的读数。

雷诺数方程:

    雷诺数 =(3160 x Q x G)/(D x V)

    其中:

    Q=单位为GPM的流体流速

    G=流体的比重

    D=单位为英寸的管内径

    V=单位为厘泊的流体粘度

最低直管长度要求

该流量计的精度受液流中泵、弯管、三通管、阀门 等的干扰影响。尽量将该流量计远离任何干扰安装 在直管中。精度所要求的距离取决于干扰类型。

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.
