BTU Meters ONICON BTU meters utilize precision matched temperature sensors that provide excellent differential accuracy. When combined with highly accurate ONICON flow meters that operate with a very wide turndown, they provide the accurate data required to effectively trend energy demand and allocate cost. Models are available that are capable of single or dual mode operation. Select the models and operating modes that are right for your application.

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 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. (Maximum flow rate 38 GPM) System-2 System-2 BTU Meters provide accurate thermal energy measurement based on signal inputs from two matched temperature sensors (included) and any of ONICON's flow meters (ordered separately). Designed for interior low voltage applications such as plenum locations, System-2 BTU meters provide total energy information via a dry contact output and optional LCD.
