KSB Announces New Balancing and Measurement Valves with Ultrasound Technology

Contributed by: PumpScout Staff

KSB, a leading producer of pumps and valves, recently released its new BOA-Control and BOA-Control IMS valve series with shut-off, balancing, and measuring included in a single valve. The valves are meant to be used for flow rate and temperature measurements that include hydraulic balancing in hot-water heating systems, air-conditioning systems and cooling circuits, and more.

Innovative ultrasound waves are able to record the flow rate, in addition to recording fluid temperature with an integrated temperature sensor. The data can be saved using a mobile measuring computer, or it can be transferred off-site to a control station.

Ultrasonic sensor measurement is possible with two sensors that are attached to the BOA valve. Even though common hydraulic balancing requires differential pressure, the valve and measuring computer on the BOA series of pumps are connected by electric cables rather than by two pressure measurement hoses. This unique feature prevents leakages and reduces injuries, in addition to easy handwheel management, since the flow rate can easily be determined.

The sensors are flexible enough to be used in two ways. The BOA-Control balancing valve can accommodate sensors for ultrasound measurement. It can be attached to the valve body, which means they don’t have to be permanently installed, so measurements can be taken on multiple valves.

In contrast, the BOA-Control IMS has sensors that are permanently connected to the BOA valve. The Boatronic MS-420 measuring computer continuously transmits the flow rate and temperature values via a 4-20 mA signal to a higher-level system. Each valve has its own computer, which means it can be used as a fully automatic control and measurement valve.

Since the initial production of these pumps, developers have further increased the measurement accuracy while extending the permissible measuring range. Error messages, measurement data protocols, and direction of flow indicators raise the system’s reliability. The design is also able to reduce the installation space required, which can save on the costs of purchasing and installing valves.
