Description

  • The Contrec 202A Loop Powered Flow Rate Totalizer design to operate with any flowmeter which produces a 4-20mA output
  • The 4 – 20mA flow meter including differential pressure devices, magnetic or vortex flowmeters.
  • Contrec 202A is powered entirely from the 4-20mA current loop hence the maximum of 2.5 volts drop across the input.
  • Contrec 202A is certified as intrinsically safe to European CENELEC standards and CSA standards for both the USA and Canada.
  • The Flow Rate Totalizer is fully programmable for linear or square law input relationships, programmable span, cutoffs also conversion factors.
  • A non-volatile memory stores all set up parameters and totals without the need for internal batteries or external power.
  • High and low alarms are standard via optically isolated solid state relay outputs.
  • Furthermore, the high alarm output can program to provide a scaled pulse output proportional to the total.
  • The Contrec 202A build with the rugged enclosure which is IP67 (NEMA 4X) polycarbonate.
  • Hence, the enclosure is entirely watertight, this enables the flow rate totalizer to mount directly on the flow meter, panel mounted, or wall mounted using a special universal bracket.
  • The Flow Rate Totalizer comes with a standard wall mounting bracket.
  • Meanwhile, a 2″ panel and pipe mounting bracket are available as an option.
