Weathering Testing Equipment. BTU meters accurately measure the thermal energy of chilled water consumption in British thermal units BTU which is a basic measure of thermal energy for commercial and residential buildings. BTU meters are used in chilled water systems for both commercial and industrial and office buildings.
They are used for billing users for energy usage. Property owners are allowed to capture the cost of heating and cooling for units that aren't caught by electrical meters by the British Thermal Unit BTU Metering.
Thermal energy is captured by a thermal meter in a unit in an effort to maintain a comfortable temperature. BTU meters calculate energy consumption by flow rate and temperature difference, using the formula:. When water passes through the pipeline, the flow meter will measure the instantaneous flow rate according to the Heat Exchange of Thermodynamics principle and send this information to the main unit.
Meanwhile, the temperature sensor will measure the temperatures of the return and supply pipe and send the information as well. The meter then integrates the cooling or heating consumption and transfers this to the computer.
Let us assume the flame will burn for exactly one hour and will give out exactly one BTU. Before starting the process, water temperature is at 50 degrees Fahrenheit, after one hour of one BTU thermal heat energy process will increase water temperature by degree Fahrenheit. Delta T is the amount of temperature difference before and after the process, So here.
Mass of water in lbs is 1. Let us assume that mass of water is 4 lbs and given BTU flame or heat energy is 2 and find the delta T ie, Temperature increased of water after one hour. Here the temperature increased is 0. Have a look at this video. How to calculate the energy consumption by BTU Meters. This system is also used to measure the performance of the energy-saving system or the loss of efficiency which is directly tied to the loss of revenue.
How to Install BTU Meter Careful attention to the site selection for the system components will help the installers with the initial installation, reduce start-up problems, and make future maintenance easier. Prerequisites knowledge to understand below calculation.
Now let us see. Note: Normally in the building, they will add extra cost like operating Cost electricity, maintenance, meter reading, invoicing tenants with energy consumption.
Now let us see,. So there is possible for a tenant to consume more heat load in a small space rather than the big space. Effective method but higher installation cost. Spread the love. Hi Mahmoud, Problem also causes due to may be other reasons like flow sensors.
