E+H超声波流量计总经销商,E+H超声波流量计外夹式或者管段式超声波流量仪表是以“速度差法"为原理，测量圆管内液体流量的仪表。它采用了良好的多脉冲技术、信号数字化处理技术及纠错技术，使流量仪表更能适应工业现场的环境，计量更方便、经济、准确。产品达到*水平，可广泛应用于石油、化工、冶金、电力、给排水等领域。
E+H超声波流量计总经销商,E+H超声波流量计原理：
根据对信号检测的原理超声流量计可分为传播速度差法(直接时差法、时差法、相位差法和频差法)、波束偏移法、多普勒法、互相关法、空间滤法及噪声法等。
超声流量计和超声波流量计一样，因仪表流通通道未设置任何阻碍件，均属*流量计，是适于解决流量测量困难问题的一类流量计，特别在大口径流量测量方面有较突出的优点，它是发展迅速的一类流量计之一。
超声波流量计采用时差式测量原理：一个探头发射信号穿过管壁、介质、另一侧管壁后，被另一个探头接收到，同时，第二个探头同样发射信号被*个探头接收到，由于受到介质流速的影响，二者存在时间差Δt，根据推算可以得出流速V和时间差Δt之间的换算关系V=(C2/2L)×Δt，进而可以得到流量值Q
,E+H超声波流量计特点：
◆*的信号数字化处理技术，使仪表测量信号更稳定、抗干扰能力强、计量更准确。
◆无机械传动部件不容易损坏，免维护，寿命长。
