FAQs of Dwyer TDS112 Thermal Dispersion Flow Switch:

Q: How is the Dwyer TDS112 flow switch installed and connected electrically?

A: The TDS112 is an insertion-type flow switch designed for quick installation using its 3/4 NPT threaded connection. Electrical connection is established via a 4-pin M12 plug, which is compatible with standard industrial connectors. All necessary mounting hardware is included, and the IP66/IP67 enclosure assists with robust, long-term installation.

Q: What types of media can the TDS112 monitor, and are there any restrictions?

A: This sensor is intended for use with compatible liquids only. It is not suitable for gases or particulates. The materials used316 stainless steel and Viton sealsoffer excellent corrosion resistance in most industrial liquid applications.

Q: When should I adjust the response time or set point on my TDS112 flow switch?

A: Adjust the response time (between 1 and 10 seconds) to suit the dynamics of your specific process and to filter out brief flow fluctuations. The set point can be calibrated over the full flow range, allowing for customization to your desired flow threshold.

Q: Where can I use the TDS112 flow switch for optimal performance?

A: Install the TDS112 in liquid flow lines where robust monitoring is needed, such as cooling systems, pump protection, or process control loops. Ensure the process temperature is between -40C and 85C and the pressure does not exceed 40 bar for safe operation.

Q: What is the process for verifying correct operation and troubleshooting the flow switch?

A: LED status indicators on the unit provide immediate feedback, showing whether flow is present or absent based on your set point. The included instruction manual details step-by-step procedures for calibration, adjustment, and troubleshooting if abnormal performance is observed.

Q: How does using the TDS112 benefit my industrial process monitoring?

A: The TDS112 delivers fast, accurate flow detection with minimal maintenance due to its non-moving thermal dispersion principle, robust construction, and reliable relay output. This ensures improved process safety and equipment protection in critical applications.
