ONICON Incorporated's System-30 BTU Meter is Now Available

Clearwater, FL - ONICON Incorporated introduced its new System-30 BTU Meter at the BOMA Show in Dallas in June. Specifically designed for smaller systems (0.8 to 38 GPM), the System-30 BTU Meter is an inline flow meter/integral BTU computer combination that provides highly accurate thermal energy measurement in chilled water, hot water and condenser water systems. An optional communications interface - available for BACnet® MS/TP, LONWORKS®, Johnson Controls N2 and Siemens P1-FLN - provides complete energy, flow and temperature data to the control system through a single network connection. Each System-30 is factory calibrated and comes complete with all installation hardware. The System-30's features include:

o certificate of NIST-traceable calibration printed with each meter
o flow accuracy of + 0.5% of reading at a calibrated velocity
o liquid temperature range of 32° to 200° F
o maximum operating pressure of 400 PSI
o semiconductor-based temperature sensors that provide delta T accuracy within 0.15° F

"The new System-30 BTU Meter is ideal for sub-metering heating/cooling costs in commercial offices, retail shops, mixed-use facilities and condominiums," explains Bowen Ierna, ONICON Incorporated's vice president of sales and marketing. "Allocating cost based on actual use helps building owners manage their energy expenses while promoting energy conservation. We see a growing demand for tenant sub-metering systems and the System-30 BTU meter is a cost-effective solution that is very accurate and easy to install."

ONICON Incorporated was founded in 1987 is a manufacturer of highly-accurate water flow meters and energy measurement systems, which are ideally suited for HVAC, municipal water and process applications. For more information, visit or e-mail
