LON® Compatible Serial Communications - Provides complete energy, ﬂow and temperature data to the control system through a single LONWORKS network connection, reducing installation costs.
Simple Installation and Commissioning - Factory programmed and ready for use upon delivery. All process data and programming functions are accessible via front panel display and keypad.
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 Certiﬁcation - Each Btu measurement system is individually calibrated using application speciﬁc ﬂow and temperature data and is provided with calibration certiﬁcates.
Precision Solid State Temperature Sensors - Custom calibrated and matched to an accuracy better than ±0.15°F over calibrated range.
Highly Accurate Flow Meters - ONICON offers a wide variety of insertion and inline type ﬂow measurement technologies including turbine, electromagnetic and vortex sensing. Each type offers unique advantages depending on the application. All ONICON ﬂow meters are individually wet calibrated and designed to operate over a wide ﬂow velocity range with accuracies ranging from ±0.2% to ±2.0% of rate depending on the model.
Complete Installation Package - All mechanical installation hardware, color coded interconnecting cabling and installation instructions are provided to ensure error-free installation and accurate system performance.
The System-10-LON 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 LONWORKS® model provides energy,
ﬂow and temperature data to the LonTalk® network using standard network variable types (SNVT). A Local indication of energy, ﬂow and temperature data is also available through an alphanumeric display located on the front of
the System-10-LON BTU Meter. An optional auxiliary input is also available to totalize pulses from another device and communicate the total directly to
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
The System-10 BTU Meter is sold complete with temperature sensors. Thermowell installation kits and ﬂow meters are purchased separately.
