Displacer Transmitter for liquids

ZM-VD transmitter with displacer utilising buoyancy principle for continuous measurement of level, interface, volume,
mass and SG in liquid media alternatively to former Helios A1.
The measurement is independent of pressure, temperature, conductivity, dielectric, foam or vapor.
