• 788 Series Differential Pressure Purge Control Level Transmitters
  • 788 Series Differential Pressure Purge Control Level Transmitters - 2
  • Generates a constant flow of compressed air to purge a downpipe
  • Integral differential pressure transmitter provides 4 mAdc to 20 mAdc output proportional to liquid level
  • All-pneumatic design does not include integral transmitter
  • Provides 1:1 pressure signal to a compatible indicator or external transducer through 1/4 in. airline tubing
  • Holds a fixed pressure differential across a precision orifice to ensure constant flow rate of 1 cfh (cubic foot per hour), making it possible to maintain a linear 1:1 response of the sensing system
  • Backpressure sensed is equivalent to the hydrostatic head pressure due to actual liquid depth
