Levitronix 100-90621超高纯度液体超声波流量计，Z形管; 0至50 LPM，3/4“OD管连接

Levitronix 100-90621超高纯度液体超声波流量计，Z形管; 0至50 LPM，3/4“OD管连接

由于DSP技术的应用，仪器的泡沫稳定性得到改进

该仪器采用非侵入式的测量方法，所以不会产生污染

有Z或U两种流量模式可供选择

该仪器被设计用于制药和半导体产业的高纯度环境的流量测量中，液体的流动被安装在流体流路径两端的两个压电传感器感应到，分别产生和接收超声波。波沿传播方向顺流时（与流体同向）加速，逆流时（与流体方向不同向）减速。两个波经过一个信号转换器的处理。其传输的时间差与流体的流速成正比。

? LEVIFLOW的流量计的标准配置包括一个流管与两个压电传感器和信号转换器，数字信号处理器（DSP）和4位数字显示器。单通道流量转换变流器采用DIN导轨安装，并设有ABD累计报警功能。该仪器可提供各种信号输出（模拟，数字输入和数字输出），可以与PC软件配置。两根RS 485总线可传输多个流量计阵列。产品内容包括：两个传感器和流量转换型传感器。注：延长电缆为必要配置，在下面单独出售。

Ultrasonic Flowmeters for Ultra High Purity Liquids, Z-Shaped Tube; 0 to 20 LPM, 1/2" OD Tube Connection

Improved bubble robustness due to DSP technology

No contamination due to noninvasive measurement

Choice of Z or U shaped flow patterns

Designed for flow measurement in high-purity processes in the pharmaceutical and semiconductor industry, flow is sensed by two piezoelectric transducers mounted at both ends of the measuring path of the fluid stream, generating and receiving an ultrasonic wave. The wave going in direction of the flow (with-stream wave) is accelerated and the wave going against (against-stream wave) the flow direction is slowed down. The two waves are processed by a signal converter. The difference of the transmit time of both waves is proportional to the velocity of the fluid.

The standard configuration of the LEVIFLOW? flowmeters consists of a flowtube with two sensor and a converter with digital signal processor (DSP) and 4-digit display. The single-channel flow converter is DIN-rail mountable and features an alarm abd totalization. Various signals (analog, digital input and digital output) are provided and can be configured with PC software. A two wire RS 485 bus allows arrays of multiple flowmeters.

What's Included:

Flowtube with two sensors and flow converter. Note: Extension cables are required and sold separately below.
