BTU Meters ONICON BTU meters use precision-matched temperature sensors that provide excellent differential accuracy. When combined with ONICON flow meters that operate with a very wide turndown, the BTU meters provide the data required to effectively trend energy demand and allocate cost. System-10 and System-30 are available with LONWorks®, Johnson Controls N2, Siemens P1, BACnet® and MODBUS interface cards.

BTU Meter Series Description System-10 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 an optional serial network interface. The System-10 BTU Meter is the ideal choice for networking to control systems. System-30 The System-30 BTU Meter provides 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.(Max flow rate 38 GPM)
