Ultrasonic Flow Measurement Technology: Pioneering Green Smart Manufacturing for Heating Systems
Recently, China officially released the ‘2024-2025 Energy Saving and Carbon Reduction Action Programme’, a policy document that not only stresses the urgency of heat metering and transformation, but also explicitly puts forward the promotion of the mode of charging according to the amount of heat. Under the impetus of this policy, the importance of ultrasonic flow measurement technology has become more and more prominent, it is not only the key to achieve accurate heat metering, but also an important tool to promote the heating system to the goal of energy saving and carbon reduction. Ultrasonic flow measurement technology: an important technical means for energy saving and carbon reduction in heating systems Ultrasonic flow measurement technology provides a reliable solution for heat metering with its high accuracy and low loss characteristics. By measuring the time difference between the propagation of ultrasonic signals in the fluid, this technology is able to accurately capture the flow rate and flow rate of the fluid, providing accurate data support for the heat distribution of the heating system. This is essential to ensure efficient operation of the heating system, optimize energy distribution and reduce energy wastage. Ultrasonic flow measurement technology: for ‘green’ ultrasonic heat meters In the ‘intelligent heating’ system, the sensor centred on ultrasonic measurement technology is like a precise ‘thermometer’, capable of accurately measuring the flow rate and flow of hot water. The sensor calculates the flow rate by the difference between the propagation time of the ultrasonic waves in the downstream and counter-flow, and then combines it with the temperature value measured by the temperature sensor to comprehensively calculate the value of the consumed heat. This high precision measurement enables the heating system to control the distribution of heat more accurately, effectively avoiding energy wastage. TAIMI High Temperature Flow Transducer : High Temperature, High Pressure, Highly Efficient Thermal Conductivity TAIMI has introduced high-temperature flow transducers based on the characteristics of heat metering. The use of highly pressure-resistant stainless steel and ceramic materials, combined with a highly hermetic design, allows the sensors to come into direct contact with the liquid medium, while effectively avoiding instability in pressure and heat resistance, ensuring the stability of the product's performance. This design significantly reduces the interference of environmental factors on the product's output and received signals, thus significantly improving the product's response sensitivity. Long-term resistance to 2.5 MPa The high-temperature flow transducer's housing material is rigid enough to withstand pressures up to 2.5 MPa for long periods of time, which is much higher than the 1 MPa pressure-resistant transducers commonly found on the market. Metal material with good thermal conductivity The metal high temperature flow transducer has excellent thermal conductivity, which helps the calorimeter sense changes in fluid temperature more accurately during the measurement process and improves the accuracy of the measurement. Drive voltage as low as 5Vp-p The transducer has a drive voltage of 5Vp-p, which not only has a low drive voltage, but also meets the testing requirements of many European and American countries, ensuring product consistency. Weather Resistant and Highly Reliable After rigorous testing and validation, the AUDIOWELL high temperature flow transducer shows excellent resistance to humidity, cold and hot shocks, and vibration, with excellent overall weather resistance, and is able to meet the requirements of industrial equipment in high temperature water metering, with high reliability. Conventional Size, Wide Matching In terms of dimensions, the probe diameter of the high temperature flow transducer is 16.8mm, which is a perfect match for conventional ultrasonic heat meters and ensures easy installation and use.   Ultrasonic Flow Measurement Technology: Helping to Transform the Heating Industry into a ‘Digital Intelligent’ Industry Thanks to the structural advantages of ultrasonic measurement technology, pipe segments fitted with high-temperature flow transducers have no moving parts inside, and therefore have low pressure loss and high accuracy. In order to further promote the development of ‘intelligent heat supply’ systems, ultrasonic flow sections with digital signal outputs are now widely used, effectively improving the stability and reliability of data transmission. The application of such ultrasonic flow measurement technology with intelligent expansion will help promote the digital and intelligent transformation of the heating industry. Through digital flow monitoring and management, heating companies can monitor the real-time operating status of the system, timely adjustment of heating strategy, to achieve more refined, intelligent energy management. This not only improves the operational efficiency of the heating system, but also brings more comfortable and economical heating services for users.       Under the strong impetus of the policy, ultrasonic flow measurement technology will play a vital role in the field of heat supply metering. It not only improves the measurement accuracy and operational efficiency of the heating system, but also helps to promote the transformation of the heating industry into ‘digital intelligence’, contributing to the achievement of energy saving and carbon reduction targets and the sustainable development of the heating industry. In China, with the in-depth implementation of the 2024-2025 Action Programme for Energy Conservation and Carbon Reduction, the application prospects of ultrasonic flow measurement technology will be broader, and its importance in the field of heat metering will become increasingly prominent.

How Piezoelectricity Works?
We have specific materials that are suited for piezoelectricity applications, but how exactly does the process work? With the Piezoelectric Effect. The most unique trait of this effect is that it works two ways. You can apply mechanical energy or electrical energy to the same piezoelectric material and get an opposite result. Applying mechanical energy to a crystal is called a direct piezoelectric effect and works like this: A piezoelectric crystal is placed between two metal plates. At this point the material is in perfect balance and does not conduct an electric current. Mechanical pressure is then applied to the material by the metal plates, which forces the electric charges within the crystal out of balance. Excess negative and positive charges appear on opposite sides of the crystal face. The metal plate collects these charges, which can be used to produce a voltage and send an electrical current through a circuit. That’s it, a simple application of mechanical pressure, the squeezing of a crystal and suddenly you have an electric current. You can also do the opposite, applying an electrical signal to a material as an inverse piezoelectric effect. It works like this: In the same situation as the example above, we have a piezoelectric crystal placed between two metal plates. The crystal’s structure is in perfect balance. Electrical energy is then applied to the crystal, which shrinks and expands the crystal’s structure. As the crystal’s structure expands and contracts, it converts the received electrical energy and releases mechanical energy in the form of a sound wave. The inverse piezoelectric effect is used in a variety of applications. Take a speaker for example, which applies a voltage to a piezoelectric ceramic, causing the material to vibrate the air as sound waves. The Discovery of Piezoelectricity Piezoelectricity was first discovered in 1880 by two brothers and French scientists, Jacques and Pierre Curie. While experimenting with a variety of crystals, they discovered that applying mechanical pressure to specific crystals like quartz released an electrical charge. They called this the piezoelectric effect. The next 30 years saw Piezoelectricity reserved largely for laboratory experiments and further refinement. It wasn’t until World War I when piezoelectricity was used for practical applications in sonar. Sonar works by connecting a voltage to a piezoelectric transmitter. This is the inverse piezoelectric effect in action, which converts electrical energy into mechanical sound waves. The sound waves travel through the water until they hit an object. They then return back to a source receiver. This receiver uses the direct piezoelectric effect to convert sound waves into an electrical voltage, which can then be processed by a signal processing device. Using the time between when the signal left and when it returned, an object’s distance can easily be calculated underwater. With sonar a success, piezoelectricity gained the eager eyes of the military. World War II advanced the technology even further as researchers from the United States, Russia, and Japan worked to craft new man-made piezoelectric materials called ferroelectrics. This research led to two man-made materials that are used alongside natural quartz crystal, barium titanate and lead zirconate titanate. Piezoelectricity Today In today’s world of electronics piezoelectricity is used everywhere. Asking Google for directions to a new restaurant uses piezoelectricity in the microphone. There’s even a subway in Tokyo that uses the power of human footsteps to power piezoelectric structures in the ground. You’ll find piezoelectricity being used in these electronic applications: Actuators Actuators use piezoelectricity to power devices like knitting and braille machinery, video cameras, and smartphones. In this system, a metal plate and an actuator device sandwiches together a piezoelectric material. Voltage is then applied to the piezoelectric material, which expands and contracts it. This movement causes the actuator to move as well. Speakers & Buzzers Speakers use piezoelectricity to power devices like alarm clocks and other small mechanical devices that require high quality audio capabilities. These systems take advantage of the inverse piezoelectric effect by converting an audio voltage signal into mechanical energy as sound waves. Drivers Drivers convert a low voltage battery into a higher voltage which can then be used to drive a piezo device. This amplification process begins with an oscillator which outputs smaller sine waves. These sine waves are then amplified with a piezo amplifier. Sensors Sensors are used in a variety of applications such as microphones, amplified guitars, and medical imaging equipment. A piezoelectric microphone is used in these devices to detect pressure variations in sound waves, which can then be converted to an electrical signal for processing. Power One of the simplest applications for piezoelectricity is the electric cigarette lighter. Pressing the button of the lighter releases a spring-loaded hammer into a piezoelectric crystal. This produces an electrical current that crosses a spark gap to heat and ignite gas. This same piezoelectric power system is used in larger gas burners and oven ranges. Motors Piezoelectric crystals are perfect for applications that require precise accuracy, such as the movement of a motor. In these devices, the piezoelectric material receives an electric signal, which is then converted into mechanical energy to force a ceramic plate to move. Piezoelectricity and the Future What does the future hold for piezoelectricity? The possibilities abound. One popular idea that inventors are throwing around is using piezoelectricity for energy harvesting. Imagine having piezoelectric devices in your smartphone that could be activated from the simple movement of your body to keep them charged. Thinking a bit bigger, you could also embed a piezoelectric system underneath highway pavement that can be activated by the wheels of traveling cars. This energy could then be used light stoplights and other nearby devices. Couple that with a road filled with electric cars and you’d find yourself in net positive energy situation.

Understanding How Ultrasonic Transducer Work
What is an ultrasonic transducer? An ultrasonic transducer is an instrument that measures the distance to an object using ultrasonic sound waves. An ultrasonic transducer uses a transducer to send and receive ultrasonic pulses that relay back information about an object’s proximity. High-frequency sound waves reflect from boundaries to produce distinct echo patterns. How Ultrasonic Transducer Work. Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing. The transducer of the sensor acts as a microphone to receive and send the ultrasonic sound. Our ultrasonic sensors, like many others, use a single transducer to send a pulse and to receive the echo. The sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse. The working principle of this module is simple. It sends an ultrasonic pulse out at 40kHz which travels through the air and if there is an obstacle or object, it will bounce back to the sensor. By calculating the travel time and the speed of sound, the distance can be calculated. Why use an Ultrasonic Transducer? Ultrasound is reliable in any lighting environment and can be used inside or outside. Ultrasonic sensors can handle collision avoidance for a robot, and being moved often, as long as it isn’t too fast. Ultrasonics are so widely used, they can be reliably implemented in grain bin sensing applications, water level sensing, drone applications and sensing cars at your local drive-thru restaurant or bank. Ultrasonic rangefinders are commonly used as devices to detect a collision. Ultrasonic Sensors are best used in the non-contact detection of: Presence Level Position Distance Non-contact sensors are also referred to as proximity sensors. Ultrasonics are Independent of: Light Smoke Dust Color Material (except for soft surfaces, i.e. wool, because the surface absorbs the ultrasonic sound wave and doesn’t reflect sound.) Long range detection of targets with varied surface properties. Ultrasonic sensors are superior to infrade sendors, because they aren’t affected by smoke or black materials, however, soft materials which don’t reflect the sonar (ultrasonic) waves very well may cause issues. It’s not a perfect system, but it’s good and reliable.
