155 Series Mass Flow Computer

Brand: Kurz Instruments

The Series 155 Mass Flow Computer is available in five models, depending on the number of flow meters and sensors in your flow meter system.

The Series 155 Mass Flow Computer integrates the functions of temperature and flow measurement, closed loop flow control, flow totalization, alarms, input/output calibration, and data acquisition for up to 22 sensors.
Features
  • Up to 22 sensor inputs for mass flow rate, temperature and 4-20 mA reference inputs
  • Multipoint calibration factor for each meter
  • Ability to group one or more inputs as a meter and to define a meter as the sum/ difference of other meters, for up to 16 meters
  • User-defined meter ID and flow area
  • User-selectable digital filtering for all input channels
  • Built‐in flow totalizers and elapsed time
  • Built-in field calibrators
  • Automatic sensor out-of-tolerance indication, alarm, and re-averaging for multipoint flow elements
  • Up to eight 4-20 mA outputs
  • Up to eight 5-amp alarm relays
  • Choice of optically isolated loop-powered or self-powered 4-20 mA outputs
  • Velocity-temperature mapping (VTM) for wide ranging process temeprature and velocity
  • RS-232C communication port for terminal operation and setup
