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.
