Improving Solar Power Efficiency Through Level and Flow Control
SEPTEMBER 2, 2014 / MAGNETROL
Solar technologies use the sun’s energy to provide electricity, hot water, process heat and cooling. According to the U.S. Energy Information Administration, solar power presently provides less than 1% of U.S. energy needs, but this is expected to increase with the development of more efficient solar technologies. One way to enhance solar power efficiency is through the use of level and flow instrumentation to drive process improvement.
TYPES OF SOLAR COLLECTORS
Different solar collectors meet different energy needs. Passive solar designs capture the sun’s heat to provide space heating and light. Photovoltaic cells convert sunlight directly to electricity. Concentrating solar power systems focus sunlight with mirrors to create a high-intensity heat source, which then produces steam or mechanical power to run a generator that creates electricity. Flat-plate collectors absorb the sun’s heat directly into water or other fluids to provide hot water or space heating.
SOLAR LEVEL AND FLOW APPLICATIONS
Heat Transfer Fluid Storage: Large-scale solar collectors for electric power generation require a heat transfer fluid (water, thermal oils, or ionic liquids) to absorb the sun’s heat for generating steam. Arrays of mirrored panels convert the sun’s energy into +750° F (+399° C) thermal energy that’s hot enough to create steam for turbines. The mirrors focus sunlight onto pipes of heat transfer fluid that run along the mirror’s centerline. The fluid then boils water to produce steam. Thermal fluids also help provide hot water and heat. Thermal fluids are typically stored in pressurized tanks that require level monitoring.
Recommended Continuous Level Technologies: Displacer Controller, Guided Wave Radar
Recommended Point Level Technologies: External Cage Float
Hot Water Storage: High-temperature solar water heaters provide energy-efficient hot water and heat for large industrial facilities. Thermal storage in buffer tanks provides interfaces between collector subsystems and energy-using systems. The preferred solar storage vessel is a vertical cylindrical tank designed for the maximum pressure of the supply water source, which may be as high as 150 psi.
Recommended Continuous Level Technologies: Displacer Controller
, Guided Wave Radar
Recommended Point Level Technologies: External Cage Float
Pump Protection: Flow switches protect pumps from damage due to leaks or if a valve is accidentally closed downstream. A flow switch will actuate an alarm and shut down the pump when flow drops below the minimum rate.
Flow Alarm: Thermal Dispersion Flow Switch for High/Low Alarm, or Flow Switch
LEVEL AND FLOW INSTRUMENTATION FOR SOLAR POWER EFFICIENCY

Increasingly, industrial process operators are recognizing the advantages of the direct measurement of mass flow rate for monitoring gases. The following article discusses the difference between volumetric flow and mass flow measurement for gas control applications, and is excerpted from the Magnetrol® Thermal Dispersion Mass Flow Measurement Handbook.
An Introduction to and Benefits of Thermal Dispersion Mass Flow Measurement
Accurate mass flow measurement of gas is difficult to obtain. The main reason is that gas is a compressible fluid. This means that the volume of a fixed mass of gas depends upon the pressure and temperature it is subject to
Consider a balloon containing one actual cubic foot of gas at room temperature (70° F) and atmospheric pressure. An increase in the room temperature causes the balloon to expand. An increase in the pressure surrounding the balloon results in a decrease in volume. Although the volume of the balloon changes with variations in pressure and temperature, the mass of the gas inside the balloon has remained the same. This illustrates how pressure and temperature affect the actual volume
There are many well-established methods of measuring the actual volumetric flow rate. However, the measured flow rate will vary with changes in temperature and pressure. For virtually all industrial process operations, the user wants to measure the mass flow rate instead of the actual flow rate. Chemical reactions work on the basis of mass relationships of ingredients. Combustion is based upon the mass flow rate of the air and the fuel. Gas consumption in a facility is based upon mass flow rate. To accurately measure mass flow, the actual flow rate must be adjusted to correct for any change in temperature and pressure.
Thermal mass flow technology is a method of gas flow measurement that does not require correction for changes in process temperature or pressure. Thermal mass flow technology also has a benefit of measurement at low velocities and greater turndown capabilities than those obtainable with other flow measurement devices. Turndown is the flow range for which the device is accurate (maximum flow / minimum flow).
What is Mass Flow Rate?
Mass Flow is the measurement of the flow rate without consideration of the process conditions. Mass flow is equivalent to the actual flow rate multiplied by the density. M = Q x ρ, where Q is the actual flow and ρ is the density. As the pressure and temperature change, the volume and density change, however the mass remains the same.
To obtain standardization of gas flow measurement, Standard conditions of Temperature and Pressure (STP conditions) are utilized. Gas flow measured at STP conditions is corrected from the actual process conditions to standard conditions (more information about standard versus actual process conditions can be found in our Thermal Dispersion Mass Flow Measurement Handbook).
The simplest way of measuring mass flow of gas is in units of cubic feet per minute or cubic meters per hour, corrected to STP conditions. This is referred to as SCFM (standard cubic feet per minute) or the metric equivalent of Nm3/h (normal cubic meters per hour). The density of a gas at standard conditions is known, thus providing a relationship between SCFM and pounds per hour or between Nm3/h and kg/h.
The conversion between the volume at actual conditions and the volume at standard conditions is based on the ideal gas law — actual volume increases in direct proportion to an increase in absolute temperature, and decreases in direct portion to an increase in absolute pressure. Consider the balloon example — as the temperature increases, the volume expands; as the pressure increases, the volume shrinks.
Absolute pressure of zero psia (pounds per square inch at absolute conditions) is a perfect vacuum. One atmosphere of pressure is defined as 14.69 psia or zero psig. The conversion between psia and psig is easy: PSIA = PSIG + 14.69. If you have a pressure gauge calibrated for psig, it will read zero at sea level and only measure gauge pressure above atmospheric pressure. The following chart will help clarify this.
Absolute zero is defined as the temperature where molecular motion stops. It is defined as 0 K (Kelvin) which is -273.16° C or 0° R (Rankine) which is -459.67° F. To convert between actual temperature and absolute temperature, simply add 460 to the temperature in degrees Fahrenheit or 273 to the temperature in Celsius.
Once we establish a set of conditions as a standard temperature and pressure (STP conditions), we can convert between the flow rate at actual conditions and the flow rate at standard conditions.
The subscript (a) refers to actual conditions; the subscript (s) refers to standard conditions.
Unfortunately, not all STP conditions are universal. Many users consider one atmosphere and 70° F as STP. Some industries use one atmosphere and 60° F as standard; others use one atmosphere and 32° F as standard. The metric equivalent is Normal conditions which are based on a pressure of one bar (14.5 psia) and 0° C.
The important issue is that Standard Conditions are not Standard and a mass flow meter needs to be able to permit the user to select the desired STP condition. An error of approximately 8% will occur if there is a difference in STP conditions between 70° F and 32° F.
Once a set of standard conditions is identified, the density of that gas at these conditions is known. Therefore, it is a simple matter to convert from SCFM to mass in pounds per hour:
In this formula, the density in pounds per cubic foot is the density at the specified STP conditions.

For two years, Flow Control’s thermal mass flow measurement technology
portal has been an important resource for flow measurement and instrumentation data. Tom Kemme, our thermal dispersion product manager, answers questions about the technology in the portal’s Ask the Expert column. This week’s blog shares some recent Q&As.
Question: Are thermal dispersion flow meters a good fit for natural gas flow measurement applications?
Answer: Natural gas flow measurement is a popular application for thermal flow meters. While thermal flow meters are not an approved custody transfer meter for natural gas, they are often used to measure natural gas flow to individual combustion sources. There are many advantages to thermal over other technologies. For example, thermal flow meters have better low flow sensitivity and a higher turndown than traditional flow meters that utilize differential pressure technology. There is more information available in the Magnetrol® white paper, Tracking Natural Gas with Flow Meters
Question: How does a thermal dispersion mass flow meter compare to a vortex flow meter for gas measurement applications, in terms of advantages and disadvantages?
Answer: There are advantages and disadvantages to every flow meter technology. The most common applications for vortex flow meters are steam and liquid flow measurement. They are also used in high velocity gas flow applications, but there are limitations in terms of the low flows a vortex flow meter can measure. Gas flow rates must be high enough to create vortices around the blunt element in the line, which is the basis of the measurement. The flow rates measured by vortex flow meters are actual flow rates, or the flow rate at operating conditions. To convert to standard conditions (mass flow) the user must make a conversion based on measurement of the operating temperature and pressure, or have a flow meter that is integrated with a multivariable transmitter.
By contrast, most thermal flow meters are used in gas flow applications. Condensed moisture in the line can cause high measurements as the relative cooling of the sensor increases. Thermal flow meters are often installed at points where condensation is knocked out of the line. Thermal flow meters have high sensitivity at low flow rates and low pressures, which is a difficult measurement for many other technologies. It is also one of the only technologies that outputs a mass flow, taking away the need for external temperature and pressure measurement.
