Dosing devices - Storz GmbH

Dosing systems, water meters and valves for every application

Dosing systems can be found in all industrial sectors, but also in everyone’s social and private environment. Easy dosing systems bottle liquids in containers or mixing vessels. Complex dosing systems assume the dosing of different row mediums to mix a new product. Even if you want to water your garden with a timer and only a specific amount of water, you could use a dosing system for this.

  • Dosings devices

  • Coin dosing devices

  • Valves

  • Water meters

Dosings devices

Dosings devices are available in different versions. They help to control the bottling or the dosing of a selected quantity of liquid. Additional to the dosing system, it’s necessary to have a flow metering and metering valve.

› Dosing systems with single staged switch-off

› Dosing systems with time control
› Transportable dosing system
› Dosing systems with subtraction switch-off
› Ex-Dosing systems
› Different variants (snap-on housing, plastic housing, switch panel mounting, wall construction)
› Different voltages
› customized configuration for sensor possible
› customized configuration for design and logotype

Coin dosing devices

Coin dosing devices are used within public showers, water supplies on camping sides, car wash facilities, holiday homes and boat piers. They are also often applied in connection to outstanding water invoices.
The coin dosing devices are sealed and are delivered with a magnetic valve and a water meter, which are also sealed.
