SY015 Flow Batch Controller

Synectic’s Flow Batch Controller is designed to accept signals from almost any flow meter and to fully control the dispensing of fluids.  Flow meter inputs can be reed switch/open collector, TTL pulse or 20mV coil.  The SY015 is easy to use with full numeric keypad for batch size entry and calibrating.

Flow Batch Controller Key features;

  • Full numeric keypad for easy batch entry
  • 3 control relays-plus alarm relay
  • User programmable filters, decimal places and meter K factor
  • No pulse alarm (requires a flow switch)
  • Data logging and printer options

The Flow Batch Controller has three control relays(configured as close, preclose and alarm) they can switch 270V at 6Amp.  A fourth alarm relay facility 240V at 1 amp can be utilised for variant applications (talk to us about your needs.)

Filters, decimal places and step sizes are all user programmable with user friendly prompts.

A no pulses alarm ensures that blockages or valve faults will not go unnoticed to minimise the chance of spillages by closing control relays if your SY015 flow batch controller detects a no flow signal.  The delay before this alarm kicks in is programmable.  In the standard product there is the option of fitting a flow switch in the line after the flow meter  as a further safety device, as if a line is broken after the meter pulses would still be coming into the computer while the liquid could be pouring on the floor so a flow switch near the end of the line can be wired into the controller which would also close control valves and turn off pumps.


DIN panel mount Noryl Case 96mm square with a depth of just 124mm behind the panel. Wall mount accessories and sealing options available.

Optional Extras;

Data logging option to store up to 4000 batches details to interrogate the unit at intervals.  Data logging is available to enable capture of all events with user programmable label batch reference and date and time stamp.  Which can be downloaded to a PC in CSV spreadsheet format.

4-20mA or voltage output proportional to measurement to be re-transmitted.  All calibration data is password protected.  With further security of an incrementing reference that makes evident any changes to measurement parameters between official calibrations.  A keylock can also be fitted to prevent calibration tampering.  The SY015 meets the requirements of QSRMC and has been used widely in the manufacturing of readymix concrete for over 20 years.
