The paper discusses the basic relationships and the state of research on a new type of bridge measurement systems with two outputs from both diagonals of a four-arm bridge. Their measuring circuits contain either two current sources or two voltage sources respectively unconventionally connected to opposite branches of these circuits. With direct current (DC), these bridges, after balancing the outputs of each of the diagonals, will enable measurements of two resistances (or two conductances) of their arms. As deflection bridges - they measure simultaneously increments of these resistances from balanced states in diagonals. The formulas for the voltages of both outputs of the systems and the balance conditions for each of them are given. As an example of application, the simultaneous measurement of stress and temperature increase with a differential two-element strain gauge was considered. The current state of theoretical work and the results of several experimental constructions of measuring instruments with a two-current bridge are briefly characterized.

“…[67][68][69][70] Accurate measurement of flow parameters can save the cost of materials and improve the quality of products, which could effectively increase economic benefits. Flow measurement is an important part of modern measurement technology, which is of great scientific significance to the development of automation in modern industry, especially in the fields of petrochemical, [71][72][73][74][75][76] biomedical, [77][78][79][80][81] energy metering [82][83][84][85][86][87][88] and pipeline safety monitoring, [89][90][91][92] showing a wide range of application prospects. At present, according to different measurement principles, the types of flow sensors can be mainly divided into volumetric type, [93][94][95] turbine type, [96,97] differential pressure type, [98,99] ultrasonic type, [100,101] and float type.…”

With the rapid development of advanced materials and manufacturing technologies, flow sensors have made significant progress in the field of mechanical engineering, which could cater to the development trend of the Internet of Things (IoT) and the ongoing Fourth Industrial Revolution. However, traditional power supply modes such as lithium batteries require regular recharging or replacement, which greatly causes too much inconvenience and maintenance consumption, and may also pose potential risks to the marine environment. The triboelectric nanogenerators (TENGs), based on the coupling effect of contact electrification and electrostatic induction, have been demonstrated to convert mechanical movements of the fluid into electrical signals with various features such as flexibility, conformability, and user‐friendliness. This review systematically summarizes for the first time the fundamental working mechanism, rational structural design, and analysis of practical application scenarios of triboelectric flow sensor as an emerging technology for flow monitoring of the Industrial IoT. According to the different fluid objects monitored, the latest representative achievements of triboelectric flow sensors can be divided into gas flow sensors, liquid flow sensors, and two‐phase flow sensors. Finally, the current challenges and future development directions of triboelectric flow sensors are examined, which can promote the further development of the field of the flow sensors.

Temperature transducers are commonly used to monitor process parameters that are controlled by various types of industrial controllers. The purpose of this study is to design and model a simple microcontroller-based acoustic temperature transducer based on the variations of resonance conditions in a cylindrical resonance tube. The transducer’s operation is based on the generation of an acoustic standing wave in the free resonance mode of generation within a cylindrical resonance tube which is converted into a train of pulses using Schmitt trigger circuit. The frequency of the generated standing wave (i.e., the train of pulses) is measured by the Arduino Uno microcontroller, where a digital pin is used to acquire pulses that are counted using a build-in software function in an Arduino IDE environment. Experimental results are performed for three sizes of diameters to investigate the effect of the diameter of resonance tube on the obtained results. The maximum nonlinearity error according to Full-Scale Deflection (FSD) is about 2.3 percent, and the relative error of the transducer is evaluated using experimental findings and the regression model. The circuit simplicity and design of the suggested transducer, as well as the linearity of its measurements, are notable.
