一、进口科氏力质量流量计概述

VTON系列科氏力质量流量计是威盾VTON根据科里奥利力原理及多变量数字处理测量技术开发的一种新型的高精度流量及密度测量仪表。实现流体质量流量的直接精密测量，而无需任何压力、温度、粘度、密度等换算或修正。其结构是由传感器单元和变送器单元两部分组成。仪表按本质安全防爆型的国家标准设计与制造。质量流量计能够直接测量流体的质量， 具有高精度（0.1%~0.2%），安装要求低（对仪表的前后直管段要求不高），运行可靠、稳定，维修率低等特点。

The VTON series Coriolis force mass flowmeter is a new type of high-precision flow and density measurement instrument developed by Weidun VTON based on the Coriolis force principle and multivariate digital processing measurement technology. Realize direct and precise measurement of fluid mass flow rate without the need for any conversion or correction of pressure, temperature, viscosity, density, etc. Its structure consists of two parts: a sensor unit and a transmitter unit. The instrument is designed and manufactured according to the national standard of intrinsic safety explosion-proof type. Mass flow meters can directly measure the mass of fluids, with high accuracy (0.1%~0.2%), low installation requirements (low requirements for the front and rear straight pipe sections of the instrument), reliable and stable operation, and low maintenance rate.

二、进口科氏力质量流量计特点

1、采用了多变量数字处理系统。强化了信号的滤波、极大提高了信号测量的灵敏度及准确度，加快了系统的响应时间，使测量更加可靠；

2、多变量数字处理系统的采用使系统组成更加灵活方便。在很多场合多变量数字处理系统模块和传感器就可以组成完整的流量测量系统，而不需要配置流量转换器。例如CNG、LNG加气机系统、定量控制系统、流量或密度单参数测量系统等；

3、测量准确度高，一般质量流量测量精度可达到0.1%-0.2%，密度测量分辨率可达到0.002-0.02g/cm^3；温度测量误差小于0.5度；

4、密度、温度测量功能实现，可以派生介质浓度测量功能（两组分介质）

1. A multivariable digital processing system was adopted. Enhanced signal filtering, greatly improved sensitivity and accuracy of signal measurement, accelerated system response time, and made measurement more reliable;

2. The adoption of multivariate digital processing systems makes the system composition more flexible and convenient. In many situations, a complete flow measurement system can be composed of multivariable digital processing system modules and sensors without the need for a flow converter. For example, CNG, LNG dispenser systems, quantitative control systems, flow or density single parameter measurement systems, etc;

3. The measurement accuracy is high, with a general mass flow measurement accuracy of 0.1% -0.2%, and a density measurement resolution of 0.002-0.02g/cm ^ 3; The temperature measurement error is less than 0.5 degrees;

4. The density and temperature measurement functions can be implemented, and the medium concentration measurement function (two component medium) can be derived
