- The new System-20 BTU Measurement System 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.
- Multiple Outputs
Each meter is provided standard with three programmable pulse outputs and one analog output. An RS-485 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-toread, back-lit display uses “smart button technology” to simplify programming and commissioning, eliminating the need for special configuration tools.
