21、own on the right. 8 误差计算及调整Error calculation and adjustment（1） 流量计的基本误差，由各检定流量点的各次测得值分别按下式计算：（容积法）Flow meters basic error, by the test flow point of the various measured values determined by the formulaE=（Vm-V）/V*100%E-流量计误差（一般指累积误差）取两位有限数字E-meter error (generally refers to the cumulative error) to

22、take a limited number of twoVm-流量计测得值（即显示值）Vm-meter measured value (that is, with values displayed)V一经修正后，流量标准装置测得值（实际值）V 1, as amended, the flow standard device measured value (actual value)由基本误差计算公式知，当VmV时，流量计基本误差为“+”值，表示流量计走快了。VmV时，流量计基本误差为“-”值，表示流量计走慢了Knowing from the basic formula for calculati

23、ng the error, when the Vm V, the flowmeter basic error + value, indicating flowmeter gone too fast. Vm V, the flowmeter basic error - value, indicating slow flow meter walk 为了使流量计误差在基本误差限之内，往往需要进行调整。即通过更换装在计数器内的一对调节齿轮（调整牙）来改变机械传动比，从而使得流量计的显示值得到调整。In order to meter error in the basic limits of error,

24、 and he often needs to be adjusted. That is mounted on the counter by replacing a pair of adjustment gears inside (adjusted teeth) to change the mechanical transmission ratio, allowing to adjust the meters display is worth.误差调整不能改变流量计的流量特性，仅使其特性曲线人为地处于新的坐标系中。Error can not change the meter to adjust

25、the flow characteristics, so only the curve artificially in a new coordinate system.一般来说，在规定的（或实际使用的）流量范围内，其最大与最小流量检定点的基本误差范围不大于规定的精度的基本误差，均可通过误差调整使其流量计基本误差合格。In general, the provisions of (or actual use of) traffic within the maximum and minimum flow rate test points, the scope of the basic error o

26、f not greater than the precision of the provisions of the basic error, the error can be adjusted to meter through the basic error of qualified .已使用过的流量计，一般先用原有的调节齿轮组进行误差检定，然后根据具体的误差情况再进行调整。Flow meter has been used, generally the first to use the original error of the regulation of gear group test, a

27、nd then depending on the error happen again to adjust.（2） 腰轮流量计误差调整方法（误差调整表使用说明）Roots Flowmeter error adjustment methods (error-adjusted using the instructions1. 设计时的标准双层齿轮是35/38，在检验时若发现流量计走慢了，即出现（1）误差，例如-1.02-0.32时，应将双层齿轮35/38换成38/41，这时误差曲线原点便由35/38齿轮对应的零位，上移到38/41齿轮相对应的+0.62的位置（参看调节齿轮表），这样误差曲线便处于新

28、的坐标系统中，而流量计的误差被调整在-0.4+0.32的范围内，便达到合格要求。Design criteria for two-tier gears are 35/38, in the examination if the meter was found to go slow, that is, under (1) error, for example, -1.02 -0.32, should be replaced 38 double-deck gear 35/38 / 41, when the error curve corresponding to the origin will be

29、zero by the 35/38 gears spaces, moved to the 38/41 gear + 0.62 corresponding to the location (see gear table adjustment), so that the error curve will be at the new coordinate system, The flowmeter is adjusted error of -0.4 +0.32 in the context, we meet eligibility requirements.2. 流量计在使用过程中，由于工作条件的变化，误差往往也会变化，导至超差。只要误差范围不超过1%，一般均可以调整合格。例如仪表周期检定后误差为-0.12+0.66，就可以进行调整
