BTU Meters

BTU meter

Accurate energy measurement is essential for managing complex central energy plants and campus environments. ONICON BTU meters provide that accuracy. Each BTU meter is provided with two bath-calibrated temperature sensors. And, when purchased with any of ONICON’s individually wet-calibrated flow meters, the accuracy of the entire BTU measurement system is directly traceable to N.I.S.T. standards. This eliminates all of the hidden errors that make it difficult to define accuracy when energy calculations are done using individual sensors connected to network controllers.

            ONICON offers two models of BTU meters. The System-10 BTU Meter is provided as a wall mounted instrument with a local display. Current based (mA) signals interconnect the temperature sensors to the BTU meter and allow for extended wire lengths without impacting accuracy. The System-30 has a compact design with an integral turbine flow sensor. It offers the accuracy of the System-10 in a cost effective design for small pipe applications. Both models provide a pulse output for totalization and optional analog outputs for rate data, as well as a wide variety of serial communications options for connection to data acquisition and control networks.



BTU Meter Series

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 through an optional serial network interface. The System-10 BTU Meter is the ideal choice for networking to control systems.


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)
