Top Entry (on site changing of measuring cartige) 2. Dual blade system (on site system check possible) - higher pressure loss SLB FLUXI/TZ 1. No (change of measuring cartridge in workshop) 2. Similar as reference wheel STRATEGY US Market Orientation Conservative Marketing PRODUCT QUALITY Medium According accuracy below Slb FLUXI /TZ 价格比较 DANIEL ACTARIS 一般相同的压力等级下，25%折扣，等于代理价。压力越高越有利。 注意我们没有DN250的表。 没有DN80表。 建议主攻范围 标定站的标准表使用。 高精度工业气体计量系统。 * 主要描述涡轮表的特点和设备区别。 * Gas turbine meters operate on the principle of flow velocity entering the meter body, being deflected by the nose cone, which greatly reduces the flow area, thus increasing velocity, giving more driving force to spin the rotor. The spinning rotor induces pulses, via magnets/coils, which are proportional to the flow rate. These pulses can be converted to flow rate and read electronically. * * * * * Tha Daniel line of Gas turbine meters can measure flows as low as 223 to as high as 25.9 million SCFH. Turndowns or rangeability from 7.6 : 1 to 228 : 1 are possible, depending on line pressure. 1 through 12 sizes are available in ANSI ratings of 125-900#. Accuracy over the stated range is + or - 1%, with much better accuracy over reduced ranges. * The
