The LDLOG control device is a system for recording chemical consumption data in the tank. The collected data is stored on a USB stick and protected against unauthorized access (log file format: CSV/EMC). LDLOG continuously collects data using a maximum of three pulse water meters and three flow sensors connected to the dosing pumps to record chemical consumption and the amount of treated water. LDLOG displays daily, monthly and annual data and can be remotely managed using the ERMES web management system. The ERMES web application allows remote management of the installations: reading, analyzing and changing the parameters of the controllers from a PC, smartphone or tablet. ADDITIONALLY: - Reduces the need for intervention and inspections of the installations. - Reports the current status of the devices and network connections (sensors, outputs, alarms, setpoints). - Instantly sends alarm notifications via SMS or email. - Generates an up-to-date report of all the controllers in the installation. - Can display the controller activity log in the form of line graphs and charts, and download it to your PC in Excel or PDF format. In addition, with ERMES you can receive alarm notifications by email with various options for reporting the device status. If your device has a GSM configuration, you can receive SMS reports on your mobile phone.
