Simple Installation and Commissioning - Factory programmed and ready for use upon delivery.
Single Source Responsibility - One manufacturer is responsible for every aspect of the energy measurement process, ensuring component compatibility and overall system accuracy.
N.I.S.T.* Traceable Calibration with Certiﬁcate -
Customer supplied application data is used to individually calibrate the ﬂow and temperature sensors using N.I.S.T. traceable standards. This is followed by a complete system calibration. A certiﬁcate of calibration is provided with each meter. Field commissioning is also available.
Precision Solid-State Temperature Sensors -
Integral sensors are custom calibrated and matched to an accuracy better than ±0.15° F over the calibrated range.
Highly Accurate Integral Flow Meter - Built-in turbine ﬂow meter is accurate to within ±0.5% of reading at the calibrated ﬂow rate and within ±2% of reading over an extended range (0.8 - 38 gpm.)
Complete Installation Package - Mechanical installation hardware, sensor cable and installation instructions are provided to ensure error-free installation and optimal performance.

The System-30-MOD provides highly accurate thermal energy measurement in chilled water, hot water or condenser water systems based on signal inputs from two integral matched temperature sensors and an integral ONICON inline turbine meter. This compact system is suitable for use in piping systems with ﬂow rates from 0.8 to 38 gpm. The Modbus RTU RS485 network interface, communicates energy, ﬂow and temperature data directly to the network. An optional backlit display is also available to provide a local indication of the same data.
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 transmitted to the network. This total is also available on the optional local display.
