The new Onicon System 20 BTU Meter provides highly accurate and reliable thermal energy measurement in heating and cooling systems. Designed for maximum versatility, the System-20 communicates via RS485 BACnet® MS/TP or MODBUS® RTU. It also includes standard 3 programmable pulse outputs and 1 analog output. 3 auxiliary pulse inputs are also included that provide a convenient network interface simplifying utility metering in the tenant spaces.

Chilled water, hot water and condenser water systems for:

  • Central plant monitoring
  • Campus energy monitoring and cost allocation
  • Performance/efficiency evaluations
  • Energy monitoring for performance contracts
  • AHU and CRAC units for commercial office tenant billing
  • Solar, geothermal and ground-source energy monitoring
  • Residential apartment and condominium tenant billing

Multiple Outputs:
  • Each meter is provided standard with three programmable pulse outputs and one analog output. An RS485 output is also provided for BACnet® MS/TP or MODBUS® RTU.

Multiple Flow Meter Options:
  • The System-20 may be ordered with any of ONICON’s inline, insertion, or clamp-on style flow meters. This allows you to match specific flow meter features and benefits to your application.

Multiple Temperature Sensor Options:
  • The System-20 may be ordered with ONICON’s precision current based sensors or a pair of matched Platinum RTDs. Each option offers exceptional accuracy and reliability.

Auxiliary Pulse Inputs:
  • Three user defined pulse inputs are provided standard. Pulses from water, gas or electric meters may be totalized in the System-20 to simplify network connectivity at the metering location.

Built-In Interval Data Logger:
  • Energy and volume totals are date/time stamped and logged within the meter along with operating status and other analytical data. Data is available via BACnet® or MODBUS®.

Suitable for Water and Water/Glycol Solutions:
  • System-20s are field programmable for water or water/glycol solutions to ensure accurate flow and energy measurement.

User Friendly Interface Display:
  • The bright, easy-to-read, back-lit display uses “smart button technology” to simplify programming and commissioning, eliminating the need for special configuration tools.
