Questions
- Question
- can flow switch TDFS-2 be usedin zone 1 hazardous location
- Answer
- Unfortunately, TDFS2 cannot be used in hazardous locations.
- Question
- Can I use this product for sediment-laden liquids?
- Answer
- The TDFS2 is designed for homogeneous liquids. However, it has no moving parts and can withstand sediment. As long as the installation instructions are followed and the unit is installed in a chemically compatible fluid, the TDFS2 can be used.
- Question
- What flow rate does the TDFS2 work with?
- Answer
- The TDFS2 can withstand high flow rates and works for setpoint ranges from 0.5 to 10 ft/s (0.15 to 3.0 m/s). As this varies by pipe size, refer to the installation manual for a full flow table by pipe size for exact applicable flow ranges.
