Level meter BA • Level metering and monitoring of liquids • Robust design • Transmitter with HART or PROFI-BUS-PA or FF as option The displacer rod, which is attached to a measuring spring using a chain, immerses into the liquid and is subject to a buoyant force proportional to the mass of the displaced liquid. Every change in the weight of the rod corresponds to a change in the length of the spring and is therefore a measure of the liquid level. The longitudinal expansion of the spring, i.e. the travel of the rod, will be transmitted from the measuring space to the indicator unit by means of a magnetic coupling. The basic version of the indicator unit consists of a scale with a pointer for displaying the liquid level. As an option, the indicator unit may be equipped with electrical transmitters for remote display or with limit switches. If the device cannot be installed from above, because, for example, a stirrer is mounted in the container, a special displacement vessel is available for lateral installation. Since the buoyancy of the displacer rod depends on the density of the measured medium, it must have been designed for the specific liquid to be measured. The BA-type level indicator is suitable for level measurement of liquid products in open containers and in containers under pressure. The device is based on Archimedes’ principle. Applications: level metering, monitoring, adjusting and control. The meter’s design makes it ideal for processes under difficult and rough operating conditions. The devices are available with additional electrical equipment for process monitoring and control. • A large spectrum of wetted materials • Magneto-resistive signal transmission • Stilling well for rough conditions (optional) subject to change without notice 1
