Factors to pay attention to when selecting flowmeters
2011-9-3 9:21:38

   流量计 时, 流量计 的选型可以从五个方面进行考虑,详细 介绍有以下几点 When choosing a flow meter , the selection of the flow meter can be considered from five aspects, and the following points are introduced in detail :
流量计 仪表性能方面:范围度、流量范围、信号输出特性、准确度、重复性、线性度、响应时间、压力损失等; 1 , meter performance aspects: range, flow range, signal output characteristics, accuracy, repeatability, linearity, response time, pressure loss, etc .;
流量计 流体特性方面:化学腐蚀、磨蚀性、结垢、混相、相变、温度、压力、密度、粘度、电导率、声速、导热系数、比热容,等熵指数; 2. Fluid characteristics of flow meter : chemical corrosion, abrasiveness, scaling, miscibility, phase change, temperature, pressure, density, viscosity, electrical conductivity, sound velocity, thermal conductivity, specific heat capacity, isentropic index;
流量计 安装条件方面:管道布置方向,流动方向,检测件上下游侧直管段长度、管道口径,维修空间、电源、接地、辅助设备、安装等; 3. In terms of the installation conditions of the flow meter : the direction of pipe layout, the direction of flow, the length of the straight pipe section on the upstream and downstream sides of the test piece, the diameter of the pipe, the maintenance space, power supply, grounding, auxiliary equipment, installation, etc.
安装流量计 环境条件方面:环境温度 湿度、电磁干扰、安全性、防爆、管道振动等; 4 , the environmental conditions of the installation of flow meters : ambient temperature and humidity, electromagnetic interference, safety, explosion protection, pipeline vibration, etc .;
  
购买流量计 经济因素方面:仪表使用寿命、备品备件 仪表购置费、安装费、运行费、校验费、维修费等。 5. In terms of economic factors for purchasing a flow meter : instrument life, spare parts , instrument purchase costs, installation costs, operating costs, calibration costs, maintenance costs, etc.
