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 sensor DWF is used for density metering of liquid media in pipes. The scale on the device shows the density rate expressed as grams per liter or kg per m³. Applications: density metering, -monitoring,
and control of liquid media. The meter’s design as mechanical device is excellent for processes under difficult and rough operating conditions. The device is available with additional electrical equipment for process monitoring and control.
