The System-30 provides highly accurate thermal energy measurement in chilled water, hot water and condenser water systems based on signal inputs from two integral, matched temperature sensors and an integral ONICON inline turbine meter. This compact system is designed to provide totalized energy for ﬂow rates from 0.8 to 38 gpm. The totalized output
is available as a solid state dry contact closure.
Each System-30 is factory calibrated and comes complete with all installation hardware. An optional backlit display is also available that provides a local indication of energy rate and total, ﬂow rate and total and supply and return temperatures.
Each System-30 is also provided with an auxiliary pulse input for totalizing the pulse output from an external device such as a water or gas meter. Pulses are totalized in an internal register and may be viewed on the optional local display or over any of the optional network interface connections.
