MEANS FOR DOSING LIQUID WITH HIGH DYNAMICS OF VOLUMES AND VISCOSITIES AND APPLICATIONS IN PARTICULAR TO OILS IN THE OIL SECTOR

摘要

Device for volumetric dosing of liquids. The device consists of a liquid metering system 1 mounted on one or more supply lines 3 pressurized by a device 2 of any kind. The volumetric dosing assembly includes a volume flow meter mounted in series with a valve controlling the flow of the liquid to be metered. The flow information is used by the control box to control the opening and closing of the valve. The control box includes a microprocessor which runs a program which compensates for dosing errors due to the response time of the control valve.
