System-10 BTU Meters The System-10 BTU Meter is a highly accurate microprocessor based instrument designed to provide full energy, flow and temperature data both at the front panel LCD and over an optional RS485, network compatible interface. The System-10 is also available with optional analog output signals for energy, flow and temperature. The System-10 is the ideal choice for networking to control systems.
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 from 32-200°F. Simple Installation and Commissioning Factory programmed and ready to use upon delivery, all process data and programming functions are accessible via front panel display and keypad. Easy-to-Operate User Interface Menu driven display and membrane keypad make viewing data easy and simplify field re-programming, when necessary. Network Compatible Serial Communications Optional communications card provides complete energy, flow and temperature data through a single network connection. Available with LONWORKS®, Johnson Controls N2, Siemens P1 and BACnet® interface cards. Highly Accurate Flow Meters Insertion turbine and inline turbine flow meters which are accurate to within ±0.5% at calibrated typical flow rate and will not exceed ±2% of actual reading over an extended 50:1 turndown range (0.4 - 20 ft/s). 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.
