Simple BTU Metering For Commercial and Industrial Applications

cooling system
Monitoring thermal energy usage at logical or localized points of consumption can provide a manager some insight into the real costs of process or space operation, as well as where the greatest benefits may be reaped from efforts at maximizing energy efficiency.

Heating and cooling systems or loops that employ water as the heat transfer medium can be simply and economically metered to determine the thermal energy usage of a space or process. The simple setup consists of a flow meter, two temperature sensors, and a calculating module that collects the output from all three devices and produces a summation of the total heat transferred through the system portion served by the subject piping. This arrangement is commonly called BTU Metering.

The size of the system being metered may be an important factor in determining the most effective metering equipment specification. A larger capacity fluid system is likely to benefit from highly accurate measurement equipment, since inaccuracy in temperature or flow measurement is leveraged by the large amount of liquid moving through the system. Heating or cooling systems of small or moderate size tend to be well suited for the application of moderate to good accuracy metering equipment, with its substantially reduced cost of installation and ownership. The key to success is selecting equipment that is well applied for the whole range of anticipated flow rates and temperatures.

If your building, plant, or process currently does not have any thermal metering, the installation of this simple device can provide information that assists in making significant progress in building an energy saving plan. More information is available from product application specialists, as well as consultation on how to most economically accomplish your process energy metering goals. Share your process measurement and control challenges with a product specialist and work together to develop effective and sensible solutions.

Video Demonstration of Weir Diaphragm Valve Operation

Diaphragm valves comprise one of many different process control valve designs, each with specific attributes making them better suited for certain applications. Selecting the right valve type for an application is a critical early step toward successful control implementation.

Familiarity and understanding of how a particular valve type functions is necessary when equipping a fluid control system. Here are some considerations for valve operation that come into play.

  • Media Compatibility:
    Industrial process control applications cover an immense range of viscosity, velocity, solids content, and other physical media characteristics that may, or may not, be acceptably addressed by some valve types.
  • Cycle Frequency:
    Some valve types are more suitable for a high frequency of on/off cycles, others are better suited to slower rates.
  • Compatibility With Sanitary or Similar Operations:
    Some industries have requirements for special cleaning, sanitizing, or sterilizing of the process flow path. A valve design that does not trap the media within the valve body and allows for full exposure of the fluid path to whatever cleaning agent is applied has certain advantages for these applications. Some cleaning operations also require a full bore or straight through flow path to allow for proper cleaning.
  • Operating Speed:
    Different valve types may have varying capabilities to provide rapid change of valve position. Valve operating speed must be compatible with process requirements that may call for either rapid or slow opening or closing.
  • Throttling Ability:
    Each valve type, through the characteristics of its closure mechanism, offers comparatively different capacity for regulate fluid flow across an extended range between completely closed and fully open.
  • Space Requirements:
    Different valve trim arrangements can predicate how much installation space a valve may require for proper operation and maintenance. For example, a valve with a rising stem will generally require more clearance than a similar capacity valve with a rotating stem.

Certainly, there are more aspects of valve operation that will be taken into account in the selection process. 

Diaphragm valves defend their niche of applications with their ability to:
  • Provide on/off or throttling service
  • Eliminate stem leakage
  • Provide bubble tight service
  • Eliminate pockets that may trap media
  • Isolate valve mechanism from media
  • Prevent contamination of media by valve parts or operation
Below is a short video that provides an animated look inside a weir diaphragm valve. The video provides a clear illustration of how the fluid flows through the valve and how the valve controls flow. There are variants of the diaphragm valve that do not use a weir, providing a straight through or full bore flow path. Their operation is similar.
