涡街流量计有什么优点？西安华恒仪表为您详细介绍：
What are the advantages of vortex flowmeters?Xi'an Huaheng Instrument for your detailed introduction:
1.两线制、三线制都分别DCDC（DC1000V）隔离；
1.Two-wire system and three-wire system are separated by DCDC(DC1000V).
2.在测量工况体积流量时几乎不受流体密度、压力、温度、粘度等参数的影响；
2.When measuring the volume flow rate under working conditions,it is almost independent of the parameters such as fluid density,pressure,temperature and viscosity.
3.支持4-20mA输出、脉冲（当量）输出、报警输出、RS485通讯输出；
3.Support 4-20 mA output,pulse(equivalent)output,alarm output,RS485 communication output;
4.仪表参数能长期稳定。本仪表采用压电应力式传感器，可靠性高，可在-25℃～+320℃的工作温度范围内工作；
4.Instrument parameters can be stable for a long time.The instrument adopts piezoelectric stress sensor,which has high reliability and can work in the range of-25~320~C.
5.应用范围广，蒸汽，气体，液体等流体流量均可测量；
5.It has a wide range of applications.The flow rate of vapors,gases and liquids can be measured.
6.基于点阵显示的人性化菜单和界面，配合明亮的背光，支持中文和英文两种语言，适合各种客户群；
6.Humanized menu and interface based on dot matrix display,with bright backlight,support Chinese and English,suitable for various customer groups;
7.支持温度、压力测量，方便气体介质温压补偿的需求；
7.Supporting temperature and pressure measurements to facilitate the requirement of temperature and pressure compensation for gas media;
8.支持流速换算显示功能，方便现场看当前流速；
8.Supports the function of flow rate conversion and display,which is convenient for viewing the current flow rate on the spot.
9.支持分屏显示功能，可以让屏幕上放大显示单个或两个参数（温度，压力，工况、标况的流量和流速等）；
9.Supporting split-screen display function,it can enlarge and display single or two parameters(temperature,pressure,working condition,flow rate of standard condition,etc.)on the screen.
10.仿真输出功能，支持4-20mA电流仿真、频率输出仿真，方便现场非实流调试；
10.The simulation output function supports 4-20mA current simulation and frequency output simulation,which is convenient for field non-real-current debugging.
11.无可动机械零件，因此可靠性高、维护量小；
11.There is no movable mechanical parts,so it has high reliability and low maintenance.
12.涡街流量计压力损失小，量程范围大，精度高；
12.Vortex flowmeter has small pressure loss,large measuring range and high accuracy.
