MODEL 9500 & 9500P MICROPROCESSOR ELECTRONIC TRANSMITTER

Integral Electronic Flow Transmitter Model # 9500P for Thermal Instrument insertion style mass flow meter

A uniquely designed microprocessor controlled electronic transmitter provides integral local control and display in an explosion proof housing for our mass flow meters.  Optional remote mounting of the electronic transmitter up to a distance of 4000 ft. from the mass flow meter sensor provides additional versatility depending on the application.

Flow signal linearity and temperature effects, determined at calibration, are corrected by the microprocessor using operating parameter data stored in the EEPROM memory.

Our model 9500P microprocessor controlled electronic transmitter provides integral local control and programming capabilities allowing for on-site modifications to many flow factors. Our newly integrated menu system is available as an opton on our Model 9500P. This provides greater flexibility to the end user by allowing for changes to the instrument as flow parameters and applications change. The integral Menu System will allow for the modification to the following:   

  • Filter Factor
  • Zero Cutoff %
  • Flow Factor or "K"
  • Full scale Flow Range
  • Pipe ID Size Changes
  • Modbus ID Values
  • Enhanced Troubleshooting Capabilities
Available Output on the 9500 Electronics are:
  • Standard 4 - 20 mA
  • Optional Modbus 485 (See our FAQ section for more specifics)
  • Compatible with Hart Communications  
9500 Electronics can be powered by 24 VDC, 110 VAC, 220 VAC, and 100 VAC.
 

MODEL 9200B MULTI-FUNCTION FLOW COMPUTER

The Thermal Instrument 9200B special purpose flow computer accepts analog input from the thermal mass flow meter and provides linearization of the sensor and scaling to the Flow Rate and Total indicators. A variety of Pulse Outputs, Analog Outputs, Control Inputs, Relay Alarms and RS-232 Outputs are provided standard. RS-485 Modbus RTU is also an ordering option.
