TURBO-4 4 Channel Turbine Meter Input Board

4 channel turbine meter input board4 Channel Turbine Meter Input Board

The TURBO-4 is a microprocessor based four channel turbine meter input board.

Each turbine meter signal can be programmed with a divisor from 1 to 999,999. The resulting solid state output represents a unit volume of liquid or gas. This output pulse can be interfaced to RTUs, computers or PLCs for further totalization or processing.


  • Programmable microprocessor design
  • On board operator interface - 2 line x 16 column LCD display with keypad
  • Divisor to 999,999
  • Programmable output pulse duration
  • Low power
  • Compatible with industry standard turbine meters
  • Displays rate, frequency and total
  • Dry contact pulse input option


  • Flow monitoring for leach mining
  • Oil field water flood monitoring
  • High speed front end for programmable logic controllers (PLC)
