This compact flow switch impresses with the latest in technology being used:

• Practically no pressure loss
• Configuration software ReadWin 2000 or FieldCare for 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

The device measures the mass flow of a liquid medium with the calorimetric measurement method. The calorimetric measuring principle is based on cooling a heated temperature sensor. Heat is removed from the sensor by forced convection due to medium flowing by. The extent of this heat transfer depends on the medium velocity and the difference in temperature between the sensor and medium (King's law). The higher the velocity or the mass flow of the medium, the greater the temperature sensor cooling.
