*Please see product specifications in the catalog sheet<\/p>\n<\/div>\n

The System-20 BTU Meter provides highly accurate thermal energy measurement in water and water\/glycol cooling, heating and condenser water systems. Energy measurements are based on signal inputs from a matched pair of temperature sensors and any of ONICON\u2019s flow meters that are ordered separately. The flexible design provides energy, flow and temperature data on the local display via analog and pulse outputs, and over BACnet\u00ae<\/span> MS\/TP or MODBUS\u00ae<\/span> RTU networks. Three auxiliary inputs are also provided to totalize pulses from other devices and communicate these totals directly to the network.<\/p>\n

Chilled water, hot water and condenser water systems for:
\n\u2022 Central plant monitoring
\n\u2022 Campus energy monitoring and cost allocation
\n\u2022 Performance\/efficiency evaluations
\n\u2022 Energy monitoring for performance contracts
\n\u2022 AHU and CRAC units for commercial office tenant billing
\n\u2022 Solar, geothermal and ground-source energy monitoring<\/p>\n

Multiple Outputs<\/h4>\n

Each meter is provided standard with three programmable pulse outputs and one analog output. An RS485 output is also provided for BACnet\u00ae MS\/TP or MODBUS\u00ae RTU.<\/p>\n

Multiple Flow Meter Options<\/h4>\n

The System-20 may be ordered with any of ONICON\u2019s inline, insertion, or clamp-on style flow meters. This allows you to match specific flow meter features and benefits to your application.<\/p>\n

Multiple Temperature Sensor Options<\/h4>\n

The System-20 may be ordered with ONICON\u2019s precision current based sensors or a pair of matched Platinum RTDs. Each option offers exceptional accuracy and reliability.<\/p>\n

Auxiliary Pulse Inputs<\/h4>\n

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.<\/p>\n

Built-In Interval Data Logger<\/h4>\n

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\u00ae or MODBUS\u00ae.<\/p>\n

Suitable for Water and Water\/Glycol Solutions<\/h4>\n

System-20s are field programmable for water or water\/glycol solutions to ensure accurate flow and energy measurement.<\/p>\n

User Friendly Interface Display<\/h4>\n

The bright, easy-to-read, back-lit display uses \u201csmart button technology\u201d to simplify programming and commissioning, eliminating the need for special configuration tools.<\/p>\n","protected":false},"excerpt":{"rendered":"

The 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 provides energy, flow and temperature data on the local display, and communicates via RS485 BACnet\u00ae MS\/TP or MODBUS\u00ae RTU directly with your BMS\/BAS.<\/p>\n

In addition, the System-20 provides an analog output signal, pulse outputs, and auxiliary pulse inputs, all of which are configurable via an intuitive user interface.<\/p>\n
