Application examples:
• Monitoring cooling water circulation systems of pumps,
turbines, compressors and heat exchangers
• Monitoring pump functionality
• Leak monitoring in process lines
• Monitoring lubrication systems
• Filter monitoring in the beverage industry
Benefits at a glance
This compact flow switch impresses with the latest in
technology being used:
• Practically no pressure loss
• Configuration software ReadWin
quick configuration and reliable storage of device settings
• Optional: 4 to 20 mA analog output to read out the flow rate
as percentage value
• Optional: second switch output or 4 to 20 mA analog output
for temperature monitoring
• Function check and process information onsite thanks to
digital display at device
• Top housing section which can be rotated 310° and rotatable
display make it possible to read the measured values in all
orientations
• DTT35: 3-A marked

Page 6: Performance Characteristics
An absolute measurement of the fluid velocity or the mass flow is not possible. The sensitivity of the calorimetric flow sensor changes with the fluid velocity. It increases with decreasing fluid velocity (for example, with water, the greatest sensor sensitivity is recorded in the range from 0.03 to 0.5 m/s).
