The flow of crude oil through pipelines in the cold weather situation is profoundly affected because of the layers of the wax deposited on the inner surface of the pipelines. To sort out this problem, we proposed a technique which can detect and monitor the deposited wax thickness in the crude oil pipelines. The proposed technique has two different systems. The first system is used for the wax thickness measurement based on the change in the capacitance, and the second system is dedicated to the transmission of the measured wax information through IoT node globally. The experimental and simulated results are reported in this paper

Target flowmeter is commonly used for measuring flow rates, but there are some shortcomings of the conventional target flowmeter, such as complex structure, low sensitivity, non-linearity. Here, a Surface Acoustic Wave (SAW) sensor-based target flowmeter has been proposed where a SAW sensor is placed on the target rod of the flowmeter. When liquid flows through the pipe in contact with the target rod, the force is produced. This force then acts on the target rod and deflects the target rod from its original position, which results strain in it. SAW sensor senses the strain level at different flow rates, and the output is in terms of delayed time response of the order of a nanosecond. The output is non-linear with respect to the flow rate and it is linearized with the help of a neural network technique. This minimizes the non-linearity error up to 0.27% of full-scale output (FSO). The modification in the target type flowmeter is done with the help of the SAW sensor in such a way that the flow transmitter can transmit sensed information through the wireless channel. Simulation and mathematical approaches are reported in this paper for the range of 0 to 1200 LPH.

In process industries, air flow rate measurement and transmission are usually performed by various passive conventional sensors. Here, air flow rate for moderate flow applications is sensed by resistive type flexible bend sensor having the characteristics of light weight, tiny size, cost-effective, fine linearity and also good repeatability. The flexible resistive type bends sensor which acts as a cantilever beam derives the linear relationship between air flow rate and the change in resistance of the sensor in the form of an electrical signal. For transmission purposes, the generated electrical signal passes through the electrical communication system which is not permeable in hazardous and inflammable areas of the process industry. Henceforth, for the data transmission purpose, Internet of Things (IoT) is being introduced in industries for avoiding explosions due to electric spark and also the real-time data is transmitted throughout the globe with the help of internet. The proposed air flow transmitter has been theoretically analyzed in this paper and the relationship of air flow rate with a transmitted voltage signal has been derived. The experiment has been performed on the fabricated prototype air flow measuring unit. The experimental results are presented in the paper which is matched with the theoretical one. The proposed IoT based air flow transmitter unit shows linear characteristic with good repeatability. The higher value of air or any clean fluid flow rate can be measured by this prototype flow transmitter by only changing the dimensions of the cantilever type bend sensor.

An Internet of Things (IoT) node-based nonintrusive, resilient liquid flow transmitter has been developed using a circular interdigital capacitor (IDC) as a primary sensor. A section of polyvinyl chloride (PVC) pipe is cut and a silicon tube of lesser diameter (compared with PVC pipe) is attached with the PVC pipe. A circular IDC is installed on the silicon tube and is used to convert the volumetric flow rate into corresponding capacitance. The change in capacitance with respect to the flow rate is nonlinear. Modified De Sauty bridge circuit is connected with the developed flow sensor to get the electrical output. To linearize the bridge output, three different linearization techniques, i.e., linear least square (LLS), genetic algorithm (GA), and artificial neural network (ANN) have been used and their statistical analysis is reported in this article. The best suited linearization technique (ANN) for the proposed sensor from the simulated result has been used in hardware implementation. This article proposes the IDC sensor access scheme design based on the IoT node and the transmission of the standard voltage signal 1–5 V using IoT node. The transmitted voltage and the received voltage have the same characteristic under the percentage error of ±0.5% of transmitted voltage. It has 0.286-pF resolution for measurement of liquid flow rate from 0 to 2000 litre per hour (LPH). This article highlights the theoretical analysis of the developed sensor to elucidate its working with maximum clarity. This sensor has been tested and its characteristics are thoroughly studied in the research workshop. Experimental results have proved that the wireless flow transmitter obeys linear characteristics and tuned well with theoretical equations based on the working principle. In addition, the proposed flow measurement is nonintrusive in nature as the circular IDC does not come in contact with the liquid flow, hence, increases the life span of the sensor.

In modern and automated process industries, Programmable Logic Controller (PLC) is one of the essential digital controllers. A PLC based controller automatically regulates the flow rate of the liquid at the desired set point. A reluctance-type target flowmeter and PLC based flow control system has been developed in the laboratory. The flow rate of the modified flowmeter is regulated continuously by using an electrical actuator. The flow rate is monitored and controlled by using the HMI screen. A PLC based controller is used to regulate the flow rate of the liquid automatically, using a modified target flowmeter and by controlling the percentage opening of the electrical actuator. The modified target flowmeter converts the regulated flow rates into change in inductance by the two ferromagnetic cores. The experiment has been performed on the developed experimental setup and tested over a range of 0–800 LPH. The theoretical analysis, along with the experimental results, has been presented in this article. The characteristic graphs show that the system follows the theoretical approach and is linear in nature. The PLC controller regulates the flow rate at the desired level, and the error is also under a permissible range of 5%.

Hydrostatic liquid level measurement is constructed on hydrostatic pressure difference creates when the height (level) in the tank or container increases / decreases. Using this principle, a Surface Acoustic Wave (SAW) based hydrostatic liquid level measurement system has been proposed using a cantilever beam at the lowermost level (datum level) of the container. When the hydrostatic pressure increases/decreases it creates force on the cantilever beam which results into change in strain. SAW sensor sense the change in strain at different liquid level. Simulation and mathematical approach is reported in this paper. The proposed transducer is novel SAW based liquid level measurement technique in comparison to conventional liquid level measurement system.

: Target flowmeter is commonly used for measuring flow rates, but there are some shortcomings of the conventional target flowmeter such as complex structure, low sensitivity, non-linearity. Here, a reluctance-type target flowmeter has been developed which converts the flow rates into an electrical signal using a modified Maxwell–Wien bridge. Two ferromagnetic cores are used in which one is attached to the target disc and in other core, coils are winded. These two cores along with coils convert the displacement of the target disc into a change in inductance. The change in inductance is converted into an electrical signal using a modified bridge. The electrical output is non-linear with respect to the flow rate. The electrical output is linearised with the help of a neural network technique. This minimises the non-linearity error up to 0.27% of full scale output (FSO). This research study includes a theoretical analysis of the proposed flow transmitter. This sensor has been designed and tested for a 0–2000 liters per hour (LPH) range in the laboratory. Experimental studies revealed that the transmitter under investigation possessed linear characteristics and obeyed the theoretical equations.

A simplified economical liquid level measurement technique has been developed for measuring the level of any type of liquid. A fabricated inter digital capacitor (IDC) is used as a primary sensor that transduces the liquid head into corresponding variation in the capacitance. This variation in the capacitance changes to an electric signal, using a modified De Sauty bridge circuit. In this paper, different types of water, such as mineral water, tap water, distilled water, and river water, are used as process liquid. This sensor can be relied for the detection of the water level, independent of the water type. The theoretical analysis of the work has been illustrated in this paper to describe the working of the proposed transmitter. The proposed sensor has been developed and laboratory tested. It is found that this transmitter exhibited the linear characteristics and followed the theoretical equations. It has 12.8-mV resolutions for measurement of water level from 0 to 15 cm range.
