The I/O-module combination then becomes either 4-C-8 or 8-C-8 (depending on whether active or passive current output is required). The latter ’8’ indicates that1 additional module can be added in the future.For I/O-module combinations, not described in the overview on the right, please consult HONEYWELL.Example for Combination of I/O’sBasic I/O2 3 1 0 0Modular I/OModular I/OModular I/OModular I/OComm 1st 2nd Comm 1st 2nd Comm 1st 2nd Comm 1st 2nd4 8 8 6 8 8 7 8 8 8 8 8 A 8 A 8 A 8 B 8 A A A B C E F C G K H G C 8 E 8 F 8 C 8 C E F C G K H G G 8 K 8 H 8 G 8GKHGD 8 8E 8 8 G 8 8 H 8 8 A 8 A 8 A 8 A 8 A A A A C C C C K K K K C 8 C 8 C 8 C 8 C C C C K K K K K 8 K 8 K 8 K 8KKKKB 8 8C 8 8 F8 0 B 8 B 8 A 0 B B B 0 E F C 0 K H E 0 E 8 F 8 F 0 E F G 0 K H H 0 K 8 H 8 KKHEx- I/O 1 2 3 2 0 0 1 2 3 0 0 1 2 D 0 0 1 2 E 0 0 12Full-Scale FlowratesFlowrates in m/s and m 3/hQ 100% in m 3/hv [m/s]0.3312DN [mm] minimumnominalmaximum2.5 0.01 0.05 0.21 4 0.01 0.14 0.54 6 0.03 0.31 1.22 10 0.08 0.853.39 15 0.19 1.91 7.63 20 0.34 3.39 13.57 25 0.53 5.30 21.21 32 0.87 8.69 34.74 40 1.36 13.57 54.29 50 2.12 21.21 84.82 65 3.58 35.84 143.35 80 5.43 54.29 217.15 100 8.48 84.82 339.29 125 13.25 132.54 530.15 150 19.09 190.85 763.40 200 33.93 339.30 1357.20 250 53.01 530.13 2120.52 300 76.34 763.41 3053.64 350 103.91 1039.08 4156.32 400 135.72 1357.17 5428.68 450 171.77 1717.65 6870.60 500 212.06 2120.58 8482.32 600 305.37 3053.70 12214.80 700 415.62 4156.20 16624.80 800 542.88 5428.80 21715.20 900 687.06 6870.60 27482.40 1000 848.22 8482.20 33928.80 1200 1221.45 12214.50 48858.00 1400 1433.52 14335.20 57340.80 1600 2171.46 21714.60 86858.40 1800 2748.27 27482.70 109930.80 2000 3393.00 33930.00 135720.00 2200 4105.50 41055.00 164220.00 2400 4885.80 48858.00 195432.00 2600 5733.90 57339.00 229356.00 2800 6650.10 66501.00 266004.00 30007634.1076341.00305364.00Flowrates in ft/s and gallons/minQ 100% in US gallons/minv [ft/s] 1 10 40 DN [inch]minimumnominalmaximum1/10 0.02 0.23 0.93 1/8 0.06 0.60 2.39 1/4 0.13 1.34 5.38 3/8 0.37 3.73 14.94 1/2 0.84 8.40 33.61 3/4 1.49 14.94 59.76 1 2.33 23.34 93.36 1.25 3.82 38.24 152.97 1.5 5.98 59.75 239.02 2 9.34 93.37 373.47 2.5 15.78 159.79 631.16 3 23.90 239.02 956.09 4 37.35 373.46 1493.84 5 58.35 583.24 2334.17 6 84.03 840.29 3361.17 8 149.39 1493.29 5975.57 10 233.41 2334.09 9336.37 12 336.12 3361.19 13444.77 14 457.59 4574.93 18299.73 16 597.54 5975.44 23901.76 18 756.26 7562.58 30250.34 20 933.86 9336.63 37346.53 24 1344.50 13445.04 53780.15 28 1829.92 18299.20 73196.79 32 2390.23 23902.29 95609.15 36 3025.03 30250.34 121001.37 40 3734.50 37346.00 149384.01 48 5377.88 53778.83 215115.30 56 6311.60 63115.99 252463.94 64 9560.65 95606.51 382426.03 72 12100.27 121002.69 484010.75 80 14938.92 149389.29 597557.18 88 18075.97 180759.73 723038.90 96 21511.53 215115.30 860461.20 104 25245.60 252456.02 1009824.08 112 29279.51 292795.09 1171180.37 12033611.93336119.311344477.23AccuracyReference conditions Medium: WaterTemperature: 20°C / 68°F Pressure: 1 bar / 14.5 psi Inlet: ≥ 5DNVersaFlow versionDN [mm]DN [inches]AccuracyCurveMag 200010….100 3/8…10 0.15% of MV + 1 mm/s 1 Mag 1000, 3000, 4000 10….1600 3/8…80 0.2% of MV + 1 mm/s 2 Mag 100 10…150 3/8…6 0.3% of MV + 2 mm/s 3 Mag 1000, 4000 >1600 >64 0.3% of MV + 2 mm/s 3 Mag 2000, 3000, 4000<10<3/80.3% of MV + 2 mm/s3For More InformationLearn more about how Honeywell’s VersaFlow TWM 9000 Electromagnetic Flow Converter can help facilitate procurement, engineering and inventory management, visit our website /ps/hfs or contact your Honeywell account manager.Honeywell Process Solutions 1860 West Rose Garden Lane Phoenix, Arizona 85027Tel: 1-800-423-9883 or 1-800-343-0228 /psSpecifications are subject to change without notice.34-VF-03-02September, 2015© 2015 Honeywell International Inc.。
E--mag转换器操作说明
E-mag电磁流量转换器操作说明第一步: 确认转换器的电源，是直流供电还是交流供电，直流型供电：11～40V.DC交流型供电：85～265V.AC 45～400Hz 第二步：通电，接通电源后仪表开始自检，自检完毕后仪表自动进入流量测量状态，即运行状态，在运行状态下，面板上的四个键，仅两个有用：“”键：第三行显示的6个只读参数的切换显示6个只读参数分别为：百分比流量、正向累积量、反向累积量、差值累积量、流速测试及报警测试。
“▽”键：总量清零键，在清零允许时，按下此键对三个累积两同时清零。
第三步：输入保密码。
在流量测量状态下，按“”键，系统开始要求输入保密码，此时光标在第一位数字上闪烁。
用“△”或“▽”键将数字设定为所需值后，按“”键移动光标到下一位数字。
重复上述步骤，完成全部码值的输入，再按“”、键进入参数子菜单。
如果输入的码值不正确，那么系统返回到测量状态。
（用户级密码：10760；工程师级：56360）第四步：当保密码确定后，可对转换器的工作参数进行选取与调整（只要是属于该保密级的参数均可），即进入参数设置状态，在此状态下，面板上四个键都有用，作用如下：“”键：切换参数页，即在菜单页之间翻页转换；“”键：切换参数项，即在菜单页中参数项之间的转换，即确认参数值。
“▽”键：改变参数值（减小）。
“△”键：改变参数值（增加）。
参数的含义和取值应当正确理解，详细请见说明书P40～P44。
第五步：返回至运行状态。
当参数设置完成后，无论在任何一菜单项中，只要用户按下“”键五秒钟，然后再松开，就会退出菜单系统返回到流量测量状态，即运行状态。

3工作原理电磁流量计的工作原理基于法拉第电磁感应定律。
当一个导体在磁场内运动，在与磁场方向、运动方向相互垂直方向的导体两端，会有感应电动势产生。
电动势的大小与导体运动速度和磁感应强度大小成正比。
在图1-1中，当导电流体以平均流速V（s m /）通过装有一对测量电极的一根内径为D（m ）的绝缘管子流动时，并且该管子处于一个均匀的磁感应强度为B（T）的磁场中。
那么，在一对电极上就会感应出垂直于磁场方和流动方向的电动势（E）。
由电磁感应定律可写做（1）式：V D B E ⋅⋅=（V）………………（1）通常，体积流量可以写作V D q v 42π=（s m /3）……………（2）由公式（1）和（2）可得到：)(43s m BE D q v π=…………………（3）因此电动势可表示为：)(q v V D BE π4=………………………（4）当B 是个常数时，公式（3）中k B D =14π，公式（3）改写为：)/(3s m kE q v =可见，流量v q 与电动势E 成正比。
U图1.1电磁流量计工作原理图1.2转换器电路结构电磁流量转换器一方面向电磁流量传感器励磁线圈提供稳定的励磁电流，以达到B是个常量；同时把传感器感应的电动势放大、转换成标准的电流信号或频率信号，便于流量的显示、控制与调节。

4.5流量信号线分体型转换器与传感器配套使用时，对被测流体电导率大于50μS/cm 的情况，流量信号传输电缆可以使用型号为RVV33×0.30mm 2的聚氯乙烯护套金属网屏蔽信号电缆。

例如STT3200专用电缆或BTS 型三重屏蔽信号接励磁电流电缆.。
4.6励磁电流线励磁电流线可采用二芯绝缘橡皮软电缆线，建议型号为RVV32×0.5mm2。
励磁电流线的长度与信号电缆长度一致。
当使用STT3200专用电缆时，励磁电缆与信号电缆合并为一根。
4.7接地转换器壳体接线端子3E应采用不小于1.6mm2接地铜线接大地。
接地电阻不大于10Ω。
4.8数字量输出:数字输出是指频率输出和脉冲输出.频率输出和脉冲输出在接线上用的是同一个输出点,因此,用户不能同时选用频率输出和脉冲输出,而只能选用其中的一种。
数字量输出高电平5v或16v输出。
也可外接电源，外接电源电压应不大于35V，导通时集电极最大电流为250mA。
若与PLC连接需要用高速计数模块接收。
4.8.1频率输出:频率输出的范围为0～5000HZ,频率输出对应的是流量百分比,F =测量值满量程值频率范围频率输出的上限可调.用户可选0～5000HZ,也可选低一点的频率:如0～1000HZ或0～5000HZ等.频率输出方式一般用于控制应用,因为它反映百分比流量,若用户用于计量应用,则应选择脉冲输出方式.4.8.2脉冲输出方式:脉冲输出方式主要用于计量方式,输出一个脉冲,代表一个当量流量,如1L或1M3等.脉冲输出当量分成：0.001L，0.01L，0.1L，1L，0.001M3，0.01M3，0.1M3，1M3计8种。
用户在选择脉冲当量时，应注意流量计流量范围和脉冲当量相匹配，脉冲当量单位应与累计流量单位一致（L或m³）。
对于体积流量，计算公式如下：QL=0.0007854×D2×V（L/S）或QM=0.0007854×D2×V×10-3（M3/S）这里：D-管径（mm）V-流速（m/s）V-流速（m/s）虽然，流量过大而脉冲当量选的过小，将会造成脉冲输出超上限，一般，脉冲输出频率应限制在20003/S以下。
当然，流量小而脉冲当量选的过大又会造成仪表很长时间才能输出一个脉冲。
另外，必须说明一个，脉冲输出不同于频率输出，脉冲输出是累积够一个脉冲当量就能输出一个脉冲，因此，脉冲输出不是很均匀的。
一般测量脉冲输出应选用计数器仪表，而不应选用频率计仪表。
