Hydro-Control

MOISTURE COUNTERBALANCE & TOUCH SCREEN WATER CONTROL SYSTEM

The Hydro-Control is the most advanced moisture counterbalance and touch screen water control system. It is typically used in the concrete industry to provide an easy method for controlling the mix cycle to ensure that the correct amount of water is automatically added in the shortest possible mixing time, based on the desired final moisture value in the product.

QUICK OVERVIEW

The Hydro-Control is a standalone unit that can be connected to a control system to easily enable the transfer of mix cycle information. With features such as automatic recipe selection and a color touch screen display, the unit is designed for simplicity of use and integration into new or existing control systems.

Using the reading from a Hydro-Mix or Hydro-Probe Orbiter sensor installed inside the mixer, the unit accurately and continuously monitors, displays and adjusts the moisture levels of the material throughout the mix cycle. Using known recipes, the Hydro-Control automatically calculates and adds the correct amount of water to the mix. This ensures that the required moisture target can be easily achieved, batch after batch. Hydro-Control also records the mixture’s homogenization percentage and signifies the end of the batching time as well as the mixer’s unloading status.

TECHNICAL CHARACTERISTICS

Operating Modes
Different operating modes can be chosen for each recipe enabling the most suitable option to be selected.

  • AUTO Mode - this mode has been designed to progressively add water until the target moisture has been achieved.
  • CALC Mode - this mode calculates the amount of water required to be added based on a moisture value taken from the dry materials in the mixer. The dry materials are for this reason unloaded and mixed while being dry inside the mixer

Recipes
32,000 recipes can be stored, which may be selected locally via the keypad or remotely using RS232 serial communication from a plant PC.

Mix Information
Enhanced mix information enabling detailed mix analysis is available from the mix log. It is also possible to view the moisture change over time for every mix.

Configuration
The Hydro-Control has been designed to work with all common methods of water addition to a mixer including weighing, metered and timed methods. Based on the chemical additives and the aggregates used in production, the mix cycle can be configured to suit different aggregate / additive combinations. The moisture can also be automatically calculated.

Easy Data Management
Upgrade, Backup and Restore via USB memory stick.

Display Information
The intuitive and ergonomically designed 8.4" LCD colour display touch screen provides a continuous graphical display of moisture and mix cycle status. Other screens include I/O configuration, sensor diagnostics and configuration, mix log information and many others.

System Interfacing
The Hydro-Control will operate as either (1) a stand-alone system where the mix cycle is started and reset using the touch screen or (2) as an integral part of a fully automated system using digital I/O and/or RS232 commands for controlling the mix sequence steps, i.e. start/stop, cement in etc.
