Non-contact density meters Ecophyspribor are the set of devices intended for non-contact density measurement of pulps and liquids in pipes (in the case of their total filling) and in various process vessels. The absence of contact between device components and tested material allows to use the Ecophyspribor density meters to control vessels filled with: - corrosive, abrasive, aggressive, toxic, biology-hazard materials; - molted and cryogenic materials; - foams, suspensions, slurries, powders, pulps, charges. Temperature and pressure inside the vessel can be of any value.
