System-30 BTU Meters 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.

Standard Features Single Source Responsibility One manufacturer responsible for the manufacture, compatibility of components, and calibration of the entire BTU measurement system. ONICON is committed to providing highly accurate and reliable systems which guarantee successful installations. N.I.S.T. Traceable Calibration with Certification Complete system-wide calibration for the entire BTU measurement system for each specific application with certification of calibration. Precision Solid State Temperature Sensors Custom calibrated and matched to an accuracy better than ±0.15°F over the calibrated range. Simple Installation and Commissioning Factory programmed and ready to use upon delivery. Network Compatible Serial Communications Optional communications card provides complete energy, flow and temperature data through a single network connection, reducing installation costs. Available with LONWORKS®, Johnson Controls N2, Siemens P1 and BACnet®  interface cards. Highly Accurate Integral Flow Meters Built-in turbine flow meter is accurate to within ±0.5% at the calibrated flow rate and within ±2% of reading over an extended range (0.8 - 38 gpm). Each ONICON flow meter is calibrated against a primary volumetric standard directly traceable to NIST with calibration certification provided. Complete Installation Package All mechanical installation hardware, color coded interconnecting cabling, and installation instructions are provided to insure error-free installation and accurate system performance.
