Knowledge about V-cone flowmeter installation
2011-10-26 16:57:44

V 流量计 现场安装 一般分为两种: 水平 安装 和垂直安装 In daily practical applications, the field installation of V- cone flow meters is generally divided into two types: horizontal installation and vertical installation . 垂直安装的时候, 需要特别 注意导压管的安装方向和变送器的零点迁移问题, 以下为几点安装的方法 However , when installing vertically, you need to pay special attention to the installation direction of the impulse tube and the zero shift of the transmitter. The following are the installation methods :

V 锥流量计 安装 侯,它 “10” 号应 对着流向。 1. When the V- cone flowmeter is installed , its "10" should face the flow direction. 于没有 10 1 符号的 V 锥流量计,安装 注意V 锥流量计上的倒角 出气 方是一致的 If the V- cone flowmeter is not marked with " 10 " and " 1 " symbols , it should be noted that the chamfer on the V- cone flowmeter is the same as the gas outlet when installing .
V 锥流量计 上、下游 侧应 有足够长的直管段, 一般情况下 ,前直段长 10D, 后直管段长 5D ( 通常 D 直径〕, 要不然就 会产生很大误差 2. There should be enough straight pipe sections on the upstream and downstream sides of the V- cone flowmeter . In general , the length of the front straight section is 10D, and the length of the rear straight section is 5D ( usually D is the diameter), otherwise it will produce Big error
V 锥流量计 安装 的地方 存在泄漏现象。 3. There should be no leakage in the place where the V- cone flowmeter is installed .
安装 的时候 注意于测量登记表配套的三阀组的方向,特别对于那些 没有 标明安装方向或 高、低压阀手柄装反的更应 仔细检查,以 防止 给高度带来 不必要 的麻烦。 4. When installing the V- cone flowmeter , pay attention to the orientation of the three valve sets supporting the registration form, especially for those that do not indicate the installation direction or the handles of the high and low pressure valves are reversely installed. Height brings unnecessary trouble.

  导压管应 垂直或 倾斜敷设 倾斜度不得小于1:12 ,为了 减少压力损失,导压管长度应 尽量短 5. The pressure tube of the V- cone flowmeter should be laid vertically or obliquely . The inclination should not be less than 1:12 . In order to reduce the pressure loss, the length of the pressure tube should be as short as possible . 减少摩擦损失 走丝 不能太小 In order to reduce friction loss , the wire should not be too small .
