As far as hot/chilled water BTU measurement systems goes, panel mounted energy computers, volumetric flow meters, and high precision temperature elements have become the technology solution of choice for most facilities and plants. With that being said, in most cases, these facilities will experience significant savings on energy, maintenance, and processing costs. While the accuracy of most […]

How to Simplify the Measurement of a Building’s Energy Consumption
As discussed in our previous article, “How to Measure Building Heating BTU without Measuring Hot Water Loop or Steam Flow” the typical building requires energy measurement devices and the measurement of both the Heating and Cooling in order to measure total building energy consumption. In order to make these measurements it has traditionally required two […]
How to Accurately Calculate Energy Consumed from Measuring Condensate
In considering the energy provided and consumed through a Steam distribution system as a billable commodity, accurate measurement is critical to provide justifiable cost statements. As discussed in the previous article, practice has been to measure the steam provided to a given point-of-use location and bill on the total energy contained in the steam even […]
The Benefits of Sub-Metering On College Campuses
College campuses can benefit from sub-metering from a business, engineering, and management perspective— all of which are vital to an institution’s sustainability. The full weight of these benefits can vary between small and larger schools. Small colleges will benefit from sub-metering simply as a way to reduce energy use and associated costs. The metered data […]
Flow Meter Calibration Is A Thing Of The Past With The New Industry Standard
Calibrating a flow meter can be a hassle and a headache, but there is a new industry standard in measuring liquid flow that will change your tune. Every so often flow meters need to be calibrated, meaning their performance must be compared to a standard, and the meter’s deviation from that standard must be determined and […]
Not All Flow Meters Are Created Equal! Part 2
Now that we have established why the flow meter is the most inaccurate component of the energy measurement system, what does this accuracy/inaccuracy really mean and how does it impact the measurement? Let’s start by defining measurement. What kind of accuracy is required to make a legitimate flow measurement? Let’s break this down into three […]
The Weakest Link in BTU Energy Measurement Systems
As energy conservation becomes more prevalent throughout society, the requirement arises for most users/industries to first measure energy usage in order to conserve. For heating and chilled water applications, this requires the installation of flow and temperature measuring devices tied to a BTU computer. From this information, the end user can assess where and how […]
