Feature
- Better reliability and life expectancy than mechanical flow switches with no paddles or vanes to wear or break, no jams in the paddle movement, and no seals on movement assembly to wear or leak
- Long operation life, as it is not affected by empty pipe by avoiding overheating with heating above the process temperature and then cooling down to process temperature
- Lower system run cost due to low pressure drop with 10% insertion into the flow (e.g. 1/8″ for 3/4″ schedule 40 pipe)
Applications
- Boiler flow proving
- Hot water heaters
- Chillers
- Liquid transfer systems
