The System-1000 provides highly accurate thermal energy measurement in chilled water, heating hot water, condenser water, and domestic water systems. Energy measurement is based on signal inputs from matched precision temperature sensors and any of ONICON’s inline, insertion, or clamp-on style flow meters. Additionally, the System-1000 can accept input from non-ONICON flow meters (4-20mA & pulse).
Typical Applications
The System-1000 is ideal for measuring two applications simultaneously. Typical applications include a combination of chilled water, heating hot water, or condenser water systems for:

The System-10 BTU Meter is a highly accurate microprocessor-based instrument designed to provide full energy, flow and temperature data both at the front panel LCD and over an optional serial network interface. The System-10 is also available with optional analog output signals for energy, flow and temperature. The System-10 is the ideal choice for networking to control systems with the availability of BACnet®, MODBUS®, LonWorks®, Johnson Controls-N2®, Siemens-P1® interface cards.
Typical Applications
Chilled water, hot water and condenser water systems for:

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® MS/TP or MODBUS® RTU directly with your BMS/BAS. 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.
Typical Applications
Chilled water, hot water and condenser water systems for:
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 communicate 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 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.
