Combimass® basic The fìeld transmitters of Riels COMBIMASS® eco series are suitable forflow rate measure- ment of compresseci air and technical gases at medium temperatures up to 130°C.The flow transmitters apply thermal dispersion technology in order to measure directly the normal volumentric or gas mass flow, regardless of the operating pressure and temperature of the Even these basic flow meters of the COMBIMASS® series already perform fully digitai signal Important features of the transmitter electronics for the purposes of practical operation are the temperature compensation and the opportunity to select different measuring modes (choice between Constant current or Constant temperature priciple). The electronics of the COMBIMASS® basic is located in a dual compartment aluminium enclosure. As an option forthis type of enclosure a IO digits LED display for indication of actual flow rate ortotalized flow is available. As a low-cost version.the circuitry can also be nstalled in a simple Vi DIN aluminium housing. In such case installation of a LED display for fìeld indication ofthe flow rate is not possible. As an option, a remote graphic display for wal or switch cabinet installation may be nstalled. On this graphic display the acutal flow rate as well as the totalized flow will be indicated at the same time. Fortransmission of the flow signal an isolated 4-20 mA analog output and a fìeld selectable pulse output are available. The flow transmitter can be combined with different sensors of the COMBIMASS® family and assembled individually according to the specifìc application. Each flow meter will be tested prior to shipment and calibrated at our CAMASS® calibration centre under actual operating conditions.
