EZO™ Universal Flow Meter Totalizer

Connect your flow sensor to this circuit to create a workable signal for your microprocessor using UART or I2C protocol.



• Reads flow rate per second, minute, hour and total flow.
• Works with any off the shelf pulsed DC flow meter regardless
   of manufacture
• Works with any DC pulse per volume flow meter
• Works with any DC pulse frequency to volume flow meter
• Programmable with up to 16 integer or floating point K factors
• On the fly linear interpretation between K factors
  for maximum accuracy
• Visual display indicating real time turbine rotation
• 1K, 10k or 100k on board pull-up or pull-down resistors
  (for flow meters that require external pull-up or pull-down)
• Comes pre programed with 4 different Atlas Scientific
   flow meters
• Data format is ASCII
