Heating Hot Water

There are two measurement opportunities in heating hot water applications; the hot water output exiting the plant and a sub-metering opportunity at the receiving end. ONICON offers an array of technologies specifically suited for this challenging application. Some of the considerations that drive the technology selection include installation requirements, accuracy requirements and maintenance implications. ONICON's insertion turbine and insertion electromagnetic flow meters are easy to install in new or existing systems, provide accurate measurements over a wide flow rate turndown, and deliver years of trouble free service in closed loop hydronic systems. For installations requiring the highest degree of accuracy, such as cost allocation, performance contracting or sub-metering, an inline electromagnetic meter may be the best solution. Where dedicated thermal energy (Btu) measurement is required, as in the case of a distributed hot water system, ONICON offers the System-10 and System-20 BTU Meters. Both are provided with a pair of precision matched temperature sensing devices and a plethora of outputs, including BACnet, MODBUS, digital I/O and analog signals. The combination of an ONICON flow meter and Btu meter creates a system with the highest level of performance in the industry. Depending on the requirements of your heating hot water application, other ONICON meters may be better suited. Please see the meters below, or feel free to contact ONICON or your local sales representative for further conversation.
