金湖捷特仪表生产的JTLU系列过热蒸汽流量计主要用于测量工业管道如气体、液体、蒸气等多种介质，其特点是压力损失小,量程范围大,精度高,在测量工况体积流量时几乎不受流体密度、压力、温度、粘度等参数的影响。无可动机械零件，因此可靠性高,维护量小。仪表参数能长期稳定。过热蒸汽流量计采用压电应力式传感器,可靠性高,可在-20℃～+250℃的工作温度范围内工作。有模拟标准信号,也有数字脉冲信号输出,容易与计算机等数字系统配套使用,是一种比较先进、理想的流量仪表。过热蒸汽流量计产品特点◆测量介质：气体、液体、蒸气◆口径规格法兰卡装式口径选择25,32,50,80,100◆法兰连接式口径选择100,150,200◆流量测量范围正常测量流速范围雷诺数1.5×104～4×106；气体5～50m/s;液体0.5～7m/s◆正常测量流量范围液体、气体流量测量范围见表2；蒸气流量范围见表3◆测量精度0.9999级1.49998级◆被测介质温度:常温–25℃～100℃◆高温–25℃～150℃-25℃～250℃◆输出信号脉冲电压输出信号高电平8～10V低电平0.7～1.3V◆脉冲占空比约50%,传输距离为100m◆脉冲电流远传信号4～20mA,传输距离为1000m◆仪表使用环境温度:-25℃～+55℃湿度:5～90%RH50℃◆材质不锈钢,铝合金◆电源DC24V或锂电池3.6V◆防爆等级本安型iaIIbT3-T6◆防护等级IP65过热蒸汽流量计产品选型代号通径流量范围㎡/hJTLU-25DN251~10(液体)25~60（气体）蒸汽流量请查看说明书，DN300以上推荐使用插入式涡街流量计JTLU-32DN321.5~18(液体)15~150（气体）JTLU-40DN402.2~27(液体)22.6~150（气体）JTLU-50DN504~55(液体)35~350（气体）JTLU-80DN809~135(液体)90~900（气体）JTLU-100DN10014~200(液体)140~1400（气体）JTLU-150DN15032~480(液体)300~3000（气体）JTLU-200DN20056~800(液体)550~5500（气体）代号功能1N无温压补偿Y有温压补偿代号输出型号F14-20mA输出（二线制）F24-20mA输出（三线制）F3RS485通讯接口代号被测介质J1液体J2气体J3蒸汽代号连接方式L1法兰卡装式L2法兰连接式代号功能2E11.0级E21.5级T1常温T2高温T3蒸汽P11.6MPaP22.5MPaP34.0MPaD1内部3.6V供电D2DC24V供电B1不锈钢B2碳钢过热蒸汽密度表一（150度-290度）压力MPa温度t（℃）1501701902102302502702900.100.150.200.250.300.400.500.801.101.401.702.002.503.003.504.004.505.006.007.008.009.0010.012.515.017.520.021.50.51640.77811.04231.30891.57832.12372.66584.39666.13137.87859.846411.629515.189018.416822.700827.16430.385235.424343.895456.720165.471384.5457108.6250158.3464206.4175250.3934327.8165384.66470.49250.74120.99181.24441.49902.01412.53804.16765.83327.51639.368811.098514.451617.570921.571325.747028.916333.629341.747553.699162.180079.8261102.0289148.7516194.4276236.6910309.9521363.29750.47070.70790.94661.18691.42871.91662.41213.93725.53427.15409.247310.567613.715016.724320.442724.330327.447531.834239.598850.678058.888375.106195.4346139.1578182.4477222.8603291.2953341.90270.45070.67770.90561.13491.36531.82972.29973.74005.23566.79138.413010.036612.977615.877619.313122.912925.978430.038437.450847.656155.596870.386388.8412129.5629170.4577209.1592273.4409320.54550.43230.65000.86841.08491.30791.75132.19923.56554.97196.42887.93529.505412.240615.036718.226621.495424.509628.243335.302044.635252.306165.666582.2486119.9781158.4766195.4568255.5786299.18800.41560.62460.83421.04451.25401.65272.10813.41104.74596.11477.52198.974411.503614.184217.053020.077823.040726.448333.154141.613349.014560.946575.6543110.3842146.4967181.6261236.9217277.79310.40010.60100.80271.00481.20771.61522.02553.27184.54455.84377.17138.535010.879413.337715.924318.660321.571724.653231.006238.592245.723156.22065.769995.7769127.6820163.4280219.0574256.42600.38570.57950.77360.96821.16341.55541.94953.14534.36125.60066.86078.144710.350012.635915.016317.499720.102822.858028.857435.570442.431651.507762.467691.1964122.5268154.2312201.2031235.0688过热蒸汽密度表二（310度-450度）压力MPa温度t（℃）3103303503703904104304500.100.150.200.250.300.400.500.801.101.401.702.002.503.003.504.004.505.006.007.008.009.0010.012.515.017.520.021.50.37240.55940.74650.93431.12241.50001.88023.02834.19435.37946.58157.80619.888811.997914.256516.552718.933321.422126.709132.548839.139946.787759.664881.6034110.5369140.3919182.5462213.67390.36000.54040.72140.90271.08441.47011.81472.92154.04195.17776.33097.49559.480611.514313.850115.74917.960820.250825.050230.223135.848542.068049.280272.010598.5531126.6895174.3185192.31640.34840.52300.69800.87321.04881.40101.75452.82273.90304.99456.09987.21869.113911.049413.028615.053917.127919.262723.700628.403733.417938.808344.756062.417886.5688116.3142166.0907171.86510.33750.50660.67590.84561.01561.35631.69832.73053.77224.82605.77796.96198.780210.630812.616214.439216.401818.410822.557029.903531.482536.321741.527456.149674.5840100.8176137.7965150.00740.32720.49120.65530.81980.98451.31441.64562.64403.65124.66735.69366.72608.475010.249312.052813.886215.752717.656521.562925.633029.869834.304439.000651.821266.834185.3228108.5430128.16140.31760.47670.63600.79550.95521.27531.59612.56353.53844.52205.51206.51178.19389.900011.630813.307714.757916.982720.690024.522428.496932.294736.934448.501561.553076.618594.4945106.63600.30860.46310.61780.77260.92771.23771.54982.48843.43354.38575.34416.30907.93329.577511.242512.999114.667916.371919.906223.402127.291331.159335.168445.802357.513770.571185.327695.13660.29980.45020.60050.75070.89891.20351.50602.41713.33454.25755.18636.12037.68989.281610.884212.508714.150715.813919.198122.663526.017029.873333.644743.543154.249765.933178.775987.0939【销售热线：15189626262张经理】==http://ina-/——金湖捷特仪表有限公司)
