差压式流量计（日本东京流机）

ODM-300型                                                                                                      1.流量检出端和流量指示装置之间即使水平距离达100米也能测定,能远距离指示.                                         2.主体结构精巧,使用简便,易于安装.                                                                    3.流量指示装置为机械式结构,指示性能可靠,重现性好.                                                           4.带分度盘显示,且指示计内含接点,可实现对设定点的报警和控制信号输出.                                         5.因为指示计的所有精密机械部分均在大气中,不受流体腐蚀.                                                      6.指示计的受压部件为隔膜片(由特殊橡胶材料制成),耐酸、耐化学物质,良好的机械性能和热性能可完全满足常温测定要求.                                                                                                  7.测量测定范围可通过节流孔(差压式流量计中,为产生流量测定所必要的压力差而设定于管路内的节流装置)调节更改.                                                                                                          8.指示计部件可以更换.                                                                                         9.同一个检测装置可转接多个指示计,实现现地控制,远程控制,或其它目的.                                        10.与其它流量计比较,因此种流量计(如标准型)可进行批量生产,所以成本更低.                                           11.在最大流速时,最大压力损失力为2.5m水柱.12.流量检测处前后的配管必须为直管.                                                                                          OEM-300型                                                                                                                用于测定工业用水、海水、油、化学物质和其他类似液体。                                                             规格：流体压力范围：0.5～10kg/cm2(G)(特殊型号17kg/cm2)                                                   流体温度范围:-20～100°C(特殊型号180°C)                                                                      流体粘度范围:0.5～100C.P.                                                                                 流体密度范围:0.5-3(g/cm2)                                                                                     流量精度:±2%(总量程)                                                                                             接线方式:法兰JIS-10KG  JIS-5KG差压:max.5mH2O                                                                节流材质:SUS-304(SUS-316或其他特殊材料)                                                              OEM-300-S (此型号在ODM-300基础上增加了电气接点,可输出接点信号以显示设定点流量是否已达到.其他参数规格同ODM-300.)                                                                                                    电气接点规格                                                                                                   开关数量:1个(内部可调整)                                                                                    开关动作:机械性(无误操作)                                                                              接点容量:125VAC,5A或250V,2.5A                                                                                       接点耐压:1000VAC,1分钟绝缘强度:1500VAC,1分钟                                                                    接点寿命:50万次以上
