Liquid dosing equipment


Liquid dosing systems are used to treat large volumes of product by dosing smaller volumes with precisions of up to 0.1% (depending on volume and application).


The liquid dosing system mainly consists of a storage system in accordance with MIE APQ (0 to 10) depending on the product. This storage is equipped with a filling system from the product container (from IBC, tank, etc.), a measurement system (cells, radar, maximum levels), and, if necessary, may have an agitation, heating, or cooling system.

Subsequently, a process delivery system is available. Depending on the required precision, the system will have a pumping system which may be controlled by measurement in the storage tank (by discount), online flow meter, or reception hopper with precision weighing.

The type of pumping system will depend on the product to be dosed, as well as the materials and treatments for the system piping.

Liquid storage and dosing systems enable greater management of raw materials, as well as greater automation of the production process. One of the main advantages of additive dosing systems is the ability to ensure uniform volume of work for dosing, reduction of errors in the process, and improvement in purchasing management due to its automation.
