The monitoring of conductivity-controlled blowdown in open cooling circuits requires precise control of the automatic blowdown valve within the conductivity range specified by the customer. By connecting conductivity probes, e.g. the NeoTec Select, via 4-20 mA or Modbus, the NeoTecMaster® enables a reliable control concept and ensures proper desalination to guarantee the required cooling capacity and water quality. By means of bus connection, relay modules can be connected to the NeoTecMaster® for controlling the flush valve and other actuators.

This controller-based monitoring technology ensures data transfer via Ethernet interface to higher-level control stations. Visualization of the measured data can be implemented in the network directly at the site.

The modular NeoTecMaster® concept with its device periphery enables measurement of up to 8 parameters. In addition to conductivity determination, the Testomat® LAB TH can be integrated for water hardness measurement in make-up water and pH and redox measurement in cooling water, both on the basis of existing measurement technology and using innovative NeoTecMaster® Select probes.
