Thermal Dispersion Mass Flow Meter - Series Scirocco

The Thermal Dispersion Mass Flowmeter, Series Scirocco 1000 measuring principle is based on the fact that heat is drawn from a heated body when a fuid flows past. A Thermal Dispersion Mass Flowmeter contains two Platinum RTD temperature sensors for this purpose. One sensor measures the current fluid temperature as a reference. The second sensor is heated and has a constant temperature differential relative to the first sensor. When the flow of air/gas starts heat is taken away from the warmer sensor. The amount of heat taken away is having a direct relation with the mass velocity of the fluid. This eliminates the need for temperature and pressure compensation. Thermal Dispersion Mass Flowmeter, Series Scirocco 1000 is available with insertion probe type or Complete Spool type with proper end connection. Insertion probe can be installed directly on the pipe carrying compressed air, with the help of clamps supplied along with probe.

Features

  • Direct measurement of mass flow
  • No pressure or temperature compensation required
  • 40:1 turndown ratio
  • Wireless data transfer possible Remote readings available on wireless
  • Pulse, milliamps or RS485 output for networking
