    SYSTEM-10 BTU METER

    The System-10-P1 BTU Meter provides highly accurate thermal energy measurement in chilled water, hot water and condenser water systems based on signal inputs from two matched temperature sensors (included) and any of ONICON’s insertion or inline flow meters (ordered separately). The System-10-P1 provides energy, flow and temperature data on a local alphanumeric display and to the network via the P1 (FLN) communications driver. An optional auxiliary input is also available to totalize pulses from another device and communicate the total directly to the network.

    APPLICATIONS
    Chilled water, hot water and condenser water systems for:

    • Commercial office tenant billing

    • Central plant monitoring

    • University campus monitoring

    • Institutional energy cost allocation

    • Performance/efficiency evaluations

    • Performance contracting energy monitoring

    SYSTEM-20 BTU METER

    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’s 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® MS/TP or MODBUS® RTU networks. Three auxiliary inputs are also provided to totalize pulses from other devices and communicate these totals directly to the network.

    System-40 BTU METER

                  The System-40 provides highly accurate thermal energy measurement in chilled water, hot water or condenser water systems. It is provided as a complete meter and includes a matched pair of platinum RTD temperature sensors and an integral inline ultrasonic flow sensor. It is available for use in ½” through 2½” piping systems with flow rates ranging from 0.03 to 250 GPM.

                 The native BACnet® MS/TP and MODBUS RTU versions of the meter communicates energy, flow and temperature data directly to the network. Three auxiliary terminals can be configured at the factory to provide pulse outputs, inputs, a combination of the two, or even a single analog output.

                Pulse outputs provide volume or energy totalization to the BMS.

                Pulse inputs can bring in totalization pulses from a local meters such as water, natural gas, or electric meters. Pulse input totals are accumulated in the internal registers and then transmitted to the RS-485 network. These totals are also available on the built-in display.

               Analog output can be programmed to provide energy rate, volume rate, or temperature data to the BMS via a 4-20 mA / 0-10V / 0-5V signal.
