 SmartMeasurement offers a variety of energy flow meters. Contact us today to learn more about these high performance, high precision flowmeters, lorem ipsum with SmartMeasurement!

For the past several decades efforts to reduce energy usage have been considerable as energy costs and environmental concerns continue to increase exponentially.  However, most of the focus has been on the Heating Ventilation, and Air Conditioning (HVAC) industry, which must contend with an ever-expanding list of regulations, guidelines, and initiatives emphasizing the importance of energy-efficient heating, cooling and ventilation systems in buildings. Reducing energy consumption offers a variety of benefits from an economic standpoint, energy efficiency leads to reduced energy costs, which in turn enhances a facility whether used in Building automation and general industry.  

Facility managers are responsible for the overall energy consumption of the buildings they oversee, having access to highly accurate and reliable flow metering technology has become vital. Flow meters make it possible for facility managers to measure the performance of various HVAC systems and ultimately make the best possible decisions to optimize efficiency and manage energy consumption.  Whereas mechanical flow meters were used for energy, today two flow technologies, ultrasonic and magnetic flow meters prove to be the best to adequately meet the needs of the HVAC industry.

HVAC systems within buildings have the potential to consume a tremendous amount of energy and generate a great deal of air pollution. For example, the American Council for an Energy-Efficient Economy estimates that buildings account for more than a third of energy use and carbon emissions in the United States. This is why so many recent regulations and initiatives, several of which are summarized below, have centered on energy-efficient buildings and have had a direct impact on the HVAC industry.

Today, a variety of flow meters with advanced capabilities are available for use by the HVAC industry to measure flow in hot or chilled water systems and provide the baseline and load profile information necessary to evaluate – and ultimately improve – the efficiency of a system. Certain flow meters demonstrating a very high rate of accuracy can also be commissioned as revenue-grade thermal energy meters, used to monitor a customer’s energy usage for billing purposes and provide an accurate picture of their energy consumption behaviors. Billing for an individual customer or tenant for measured energy usage is now more popular which makes energy flow meters serve as revenue-grade thermal energy meters for billing. In this type of application, Energy flow meters are able to calculate BTUs by measuring the flow rate of hot or chilled water as well as the supply and return temperatures.

Electromagnetic or Magnetic energy flow meters

Smartmeasurement’ s ALMAGEG are suitable for measuring the flow of almost all electrically conductive liquids, pastes and slurries, and an appropriate replacement for traditional mechanical flow meters when greater functionality is required, electromagnetic flow technology is the right choice for the vast majority of hot and chilled and water applications, including new installations and small line sizes below 24 in (600 mm).  For more discussion on magnetic flow meters please go to: https://www.smartmeasurement.com/magnetic-flow-meters/

Electromagnetic flow meters offer several important benefits to the HVAC industry, including ease of operation and maintenance due to a lack of moving parts, a high level of durability, and the flexibility for either compact or remote installation using the same sensor and transmitter. The ALMAGEG offers the additional benefit stored sensor calibration data and transmitter settings for the lifetime of the product. Should the transmitter ever need to be replaced, the new transmitter uploads all previous settings and resumes measurement without any need for reprogramming – saving facility managers valuable time and money.  The ALMAEG offers an advantage over ultrasonic meters because it can measure accurately if particles or bubbles are present in the fluid over ultrasonic technologies because most cannot handle less than 1% bubbles or solids in the flow stream Magnetic flowmeters are also more widely used in general industrial energy measurement such as chillers, heat exchangers or where higher accuracies are required.

The advantages and disadvantages of Magnetic energy meters:

Advantages:

  • Most accurate energy flow meter up to 0.2% of reading

  • Able to measure with particles and bubbles present

  • Can measure wide temperature ranges of -58-356 °F (-50 ~ +180˚C)

Disadvantages:

  • Higher cost than ultrasonic alt

  • Higher installation costs than clamp-on ultrasonic meters

  • Cannot be used in portable energy measurement

Inline ultrasonic Energy flow meters

Inline ultrasonic energy flow meters such as Smartmeasurement’ s Alsonic Building Automation-Energy meters or the AlsonicBAEG are a low-cost alternative to mechanical hot water/BTU meters. For more discussion on ultrasonic flow meters please go to: https://www.smartmeasurement.com/water-energy-ultrasonic-flow-meters/

The ALSONICBAEG employs transit-time ultrasonic flow technology combined with two integrated PT1000 RTD temperature sensors for calculating both total and instantaneous energy consumption. The AlsonicBAEG energy meters are available in sizes from ½” to 1½” with brass and NPT threads (other materials are available upon request) with flanged carbon steel for sizes 2″ and over.  Standard temperature of up 95°C (203°F) and option of up to 130°C (266°F) available upon request. The Alsonic BAEG meet the standards for residential and commercial utility metering. The alphanumeric LCD displays heat consumption, temperature, flow total, operation time, flow rate, etc. with data storage of up 18 months of operation.  The meter also has a remote readout configurable with CJ/T188 and N1434 BTU/heat meter standards configurable in RS485/Modbus, BACnet, GSM/GPRS wireless, integrated into any AMR/AMI systems

Advantages:

  • Lowest cost energy flow meter

  • Able to connect with standard hot water pipes meters

  • Can be used in homes and apartments

  • Can accurately measure in small pipes than clamp-on version

Disadvantages:

  • Cannot measure water with more than 1% particles/bubbles

  • Higher installation costs than clamp-on ultrasonic meters

  • Cannot be used in portable energy measurement

  • Temperature range of -32-195 °F (0 ~ +90˚C) lower than magnetic energy meters.

Clamp-on ultrasonic Energy flow meters

The AlsonicEG clamp on ultrasonic energy meters are extremely useful for retrofit projects in which the pipeline cannot be isolated, as well as for hot and chilled water sub-metering. Overall, clamp-on technology is optimal for measuring flow in a wide range of building management, power plant, university and district energy heating and cooling applications, including condenser water, potable water, glycol, thermal storage, river and lake water, lake source cooling, chemical feed, and ammonia feed.  Moreover, the AlsonicEG has a portable version the AlsonicPLEG with its clamp on temperature sensors can be used for site surveys, or applications where a fixed system is not necessary.

Clamp-on ultrasonic flow meters also offer the benefit of being quick, easy and cost-effective to install and maintain as part of an existing HVAC or any industrial application. These externally mounted sensors require no cutting of pipes, interruption of flow or periodic cleaning. Such a feature makes clamp-on flow meters among the most versatile on the market, as they can be installed anywhere along a hot or chilled water line.

Smartmeasurement’ s AlsonicEG offers a clamp-on ultrasonic flow meter designed specifically with the unique and challenging needs of the HVAC industry.  The accuracy, wide bidirectional rangeability and high level of sensitivity of this meter improve the energy efficiency of most HVAC applications with no pressure drop, while avoiding the performance and readability problems that negatively impact the performance of conventional intrusive thermal energy flow meters. The AlsonicEG analog input capability allows for calculation of cooling load (kW/ton), coefficient of performance (COP) and energy efficiency ratio (EER). It also serves as a high-precision thermal energy flow meter with 1000 Ohm platinum RTD clamp-on or insert sensors combined with four-wire temperature cables.

Advantages

  • No installation costs – strapped (clamp-on) on the pipe

  • Can measure in very large pipes

  • Can be used in portable applications

Disadvantages:

  • Limited amount of particles or bubbles (1-2%)

  • Accuracies of 1-2% lower magnetic energy meters

  • Temperature range of -22~+230 °F (-30 ~ +110˚C) lower than magnetic energy meters
