新超声波流量仪家族提供一个很有用的多功能应用组合，操作简单、可靠，可用于多种过程应用经济。
Clark solutions clarksonic 超声波流量仪，据报告称此超声波流量仪非常适用于在非常清洁的液体和许多夹带固体的液体中测量流量。此流量仪的应用包括：在冷冻的或是用于HVAC热水中监测流速。
ClarkSonic家族拥有两个主要的操作系列：CSLFC和CSLFB。CSLFC模型超声波传送器设计用于测量四分之三英寸和三英寸管，且流量达400GPM。CSLFB型超声波传送器，设计用于四英寸和十英寸管，流量达3000GPM的处理。
公司称ClarkSonic流量计的核心就是一个独立的ASIC混合信号。其能实现复杂的计时，控制和变频器驱动电路可被集合在一起，装在一个电路板上。ASIC利用特殊的运算法则，提高标准的单径测量技术。ClarkSonic传送器利用环鸣方法，加上超声波变频器交替变换接收和传送，可测量逆流和顺流间传送声波飞行时间的差异。
如果脉冲从流量方向发出的话，从传送变频器到接收变频器脉冲的声脉冲飞行时间将被缩短，如果从脉冲流量相反方向发出的话，从传送变频器到接收变频器脉冲的声脉冲飞行时间将被加长。通过改变传送和接收变频器，这些传送时间上的区别，可被用于计算流速。环鸣方法的主要优势是在给定的液体里，液体的速度可被独立测量。应用此种方法，输出将不受液体温度、密度和黏性所影响。WWW_PLCJS※COM－PLC－技.术_网(可※编程控※制器技术门户)

Listen in: Ultrasonic technology offers versatility, economy
New family of ultrasonic flowmeters offers a useful combination of application versatility, simple operation, reliability, and economy for many general process applications. （Click here to hear comments from Don Tyler, president of Clark Solutions.）
Clark Solutions ClarkSonic ultrasonic flowmeters are reportedly well suited for measuring flow in most clean liquids and many liquids with entrained solids. Applications include monitoring flow rates of chilled or heated water for HVAC installations, as well as in municipal, process, and industrial systems. The company says the family frees users from having to calibrate the transmitter to fluid temperature, viscosity, or density, making them very easy to deploy and very reliable. Output is standard 4-20 mA with user definable flow units.
ClarkSonic family has two main operating ranges. Model CSLFC ultrasonic transmitters are designed for flows to 400 GPM in ¾ in. to 3 in. pipe, and Model CSLFB ultrasonic transmitters are designed for flows to 3000 GPM in 4 in. to 10 in. pipe. All models feature no moving parts, long-term stability, no pressure drop, broad fluid compatibility, and high accuracy at prices often below other similar instruments. WWW_P※LCJS_CO※M－PLC－技－.术_网
