一、进口气体腰轮流量计概述

进口气体腰轮流量计它由传感器和转换显示仪组成，传感器采用多叶片的转子感受流体的平均流速，从而推导出流量或总量。涡轮流量计是一种速度式仪表，它具有精度高，重复性好，结构简单，运动部件少，耐高压，测量范围宽，体积小，重量轻，压力损失小，维修方便等优点，用于封闭管道中测量低粘度气体的体积流量和总量。每台表的叶片都经过动平衡严苛检测，通过音速喷嘴标定台逐台多点标定后才能够准许出厂。它先将流速转换为涡轮的转速，再将转速转换成与流量成正比的电信号。其输出信号为频率，易于数字化。产品主要有基本型和温压补偿型两种形式，基本型测量单一流量信号，温压补偿型可统一实现测量温度、压力、标方流量的测量。每种形式都有整体、分体结构，以适用不同的安装环境。已广泛应用于石油、化工、科研、轻纺、锅炉等领域。

The gas waist wheel flow meter consists of a sensor and a conversion display. The sensor uses a multi-blade rotor to sense the average flow rate of the fluid, thereby deriving the flow rate or total volume. Turbine flowmeter is a speed meter. It has the advantages of high accuracy, good repeatability, simple structure, few moving parts, high pressure resistance, wide measurement range, small size, light weight, small pressure loss, and easy maintenance. It is used for Measurement of volume flow and total quantity of low viscosity gases in closed pipes. The blades of each meter have been rigorously tested by dynamic balance, and can be allowed to leave the factory only after passing multi-point calibration on a sonic nozzle calibration table. It first converts the flow rate into the rotation speed of the turbine, and then converts the rotation speed into an electrical signal proportional to the flow rate. Its output signal is frequency and is easy to digitize. The product mainly comes in two forms: basic type and temperature-pressure compensation type. The basic type measures a single flow signal, while the temperature-pressure compensation type can uniformly measure temperature, pressure, and standard flow. Each form has an integral or split structure to suit different installation environments. It has been widely used in petroleum, chemical industry, scientific research, textile, boiler and other fields.
