Maintain the Quality of Stored Diesel Exhaust Fluid
The Veeder-Root DEF Recirculation Monitoring Solution is an add-on software feature for the TLS-450PLUS Automatic Tank Gauge (ATG). It provides a simple mechanism to automate your DEF heat trace or recirculation control to help prevent DEF product from freezing or overheating in lines that utilize DEF in bulk dispensing systems.
The DEF recirculation solution utilizes a temperature sensor to measure the temperature of the DEF fluid between the tank and dispensing system. This allows the TLS-450PLUS ATG to control relays assigned to the DEF Submersible Turbine Pump (STP) to recirculate the fluid in the event it goes below or above a present temperature setting. In addition to controlling the STP to move fluid through the system, the TLS-450PLUS ATG can utilize its temperature sensing technology to manage the heat trace systems and provide a heat source for the DEF piping system.
Key Features
Multi-tiered temperature-based control of recirculation and heat trace systems.
- Use recirculation first to avoid freezing lines
- Add heat trace only when temperature demands it
- Program notifications for alarm conditions
In cold climates, minimize energy costs by operating freeze prevention only when warranted.
- Temperature-based pump control for recirculation
- Temperature-based relay control for powering heat trace
In hot climates, utilize recirculation to help prevent product from degrading in the lines.
