By using ultrasonic sensors, BOA-Control and BOA-Control IMS offer shut-off, balancing and measuring functions in a single valve.

新的BOA-Control和BOA-Control IMS Valve系列的KSB Aktiengesellschaft在单个阀中统一了三个功能：关闭，平衡和测量。
The valves are mainly used for hydraulic balancing in hot-water heating systems, air-conditioning systems and cooling circuits as well as in other applications for flow rate and temperature measurement. This design saves the costs of purchasing and installing additional valves. It also reduces the installation space required.
The valve series uses ultrasound waves to record the flow rate via transit time difference measurement. In addition, an integrated temperature sensor precisely records the fluid temperature. The data gathered can either be saved on site using a mobile measuring computer or transferred continuously to a control station via a stationary measuring computer.
Two sensors attached to the BOA valve enable ultrasonic sensor measurement. Unlike the differential pressure measurement common for hydraulic balancing, the valve and the measuring computer are connected by electric cables rather than by two pressure measurement hoses. This prevents leakages and reduces the risk of operating personnel getting injured when working with hot water. Also, irrespective of the valve travel positions and the minimum differential pressures, the flow rate can be determined while the handwheel is being moved.
根据应用的不同，传感器可以通过两种不同的方式附着：BOA控制平衡阀旨在容纳传感器以进行超声测量。可以通过磁连接器将它们连接到阀体上，而不是永久安装。与移动船型MS计算机一起，可以对该设计的任意数量进行测量。
另一种选择是类型系列BOA控制IMS。在这里，传感器已永久连接到BOA阀。Boatronic MS-420测量计算机连续测量通过4 - 20 MA信号传输流量和温度值。在此设计中，每个阀门都有自己的计算机安装在阀门上。结合智能电动执行器，该阀也可以用作全自动控制和测量阀。
Since the previous generation the developers have further increased the measurement accuracy and extended the permissible measuring range. Further additional functions such as error messages, measurement data protocols and direction of flow indicators raise the system’s reliability.
