What is the purpose of BTU meter?

BTU meters, also called energy meters, are used to bill users for energy usage and can also be used to measure the performance of energy-saving measures or the loss of efficiency within the system which impacts revenue.

What is BTU reading?

BTU’s are a unit of measurement equivalent to the amount of heat required to increase the temperature of one pound of water by 1 degree Fahrenheit. BTU is an abbreviation for British Thermal Unit and has been used since the late 17th century.

How do you calibrate a BTU meter?

To perform Master meter calibration:

1. Place the master meter in series with the flow meter under test.
2. Compare the readings of the master flow meter and flow meter using a measured volume of liquid.
3. Calibrate the flowmeter under test to conform with the master flow meter calibration.

What is chiller BTU?

BTU (British Thermal Unit) is a unit of measure often used to describe chiller capacity. A single BTU is the amount of energy required to raise one pound of water one degree Fahrenheit. Our chillers are rated in BTU/hr, this is the capacity of cooling the chiller can preform in an hour.

What is the difference between flow meter and BTU meter?

When the water or other liquid passes through the pipeline, the flow meter measures the instantaneous flow rate and sends it to the BTU meter then the temperature sensor measures the return pipe temperature and supply pipe temperature and also sends it to BTU meter.

Where do I put my BTU meter?

The BTU Meter may be installed in horizontal or vertical pipelines (either up or down flow). The Card Slot should be positioned to face downward. Insure that the BTU Meter is completely full of water at all times.

Why do flow meters require regular calibration?

Regular calibrations assure you that the flowmeter’s measurements are as accurate as their specifications say they are. Even the most rugged flowmeters can fall out of calibration. All instruments’ performance degrades over time; parts wear out or break.

Why is it important to calibrate the water meter or other flow meter?

Flow meters should be calibrated closely to the actual conditions in which it is used. This will ensure accuracy of results and provide a history of flow meter performance, which will help determine a schedule for recalibration.

How is chiller flow rate measured?

Divide the cooling rate that you need, measured in British thermal units (BTUs) per hour by this answer. For example, if the chiller must absorb 3,840,000 BTUs each hour: 3,840,000 ÷ 13,000 = 295.4. This is the chiller’s minimum cooling rate, measured in gallons per minute.

How does the BTU meter work?

The system real-time detect the temperature of supply and return pipe. It also monitors the instantaneous flow rate according to the Heat Exchange of Thermodynamics principle. The BTU meter automatically integrates energy consumption and transfers it to the computer.

What factors affect the number of Ahu’s to be installed?

Location and size of AHU room/ rooms will also impact the no. of AHU’s to be installed. Also, while deciding on number/ size of AHU’s there has to be a trade off between energy efficient conditining and easier operation.

What is the temperature increased in BTU measurement system?

Here the temperature increased is 0.5 degree-Fahrenheit. BTU Measurement System is used to measure individual energy consumption in any liquid heating/cooling systems. 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.

What is the difference between AHU design and Rh control?

Sensible cooling usually is easier part of AHU design than RH control. Cooling/ heating coils design have to cater for extreme ends of outside weather conditions. If we expect a big RH correction for incoming fresh air, size of cooling coils and therefore space requirement can be a limitation in design of AHU’s.
