The four process control parameters are temperature, pressure, flow, and level. Modem process level detection systems are varied and ubiquitous in modem chemical plants there are thousands of processes requiring Hquid level indication and Hquid level control. From accumulators to wet wells, the need for level devices is based on the need for plant efficiency, safety, quaUty control, and data logging. Unfortunately, no single level measurement technology works rehably on all chemical plant appHcations. This fact has spawned a broad selection of level indication and control device technologies, each of which operates successfully on specific appHcations. 

Capacitance is an extremely flexible level measurement technology. Although the approach is electronic, the sensing probe is a mechanical object...

Thanks to advances in miniaturization and developments in sensors and measurement technologies, it is already possible to collect a considerable amount of health-related information from wearable or embedded devices, and numerous new devices are also in the pipeline (Table 32.1). Some of these devices function on a constant basis, whereas others take intermittent mea-... 

Understanding the production process involves knowing the function of each step to be covered by the Q system. Typical issues that must be discussed include the different process steps, the functions of each step, the measurable technological parameters such as time, temperature, and pressure, the measuring units present, the available analysis techniques and tools, and the way the process is orgaifized (continuous, batch, convergent, divergent, etc.). 

Monitoring and Measuring Technologies using the latest in Satellite-Based Remote Sensing (e.g., NASA s EOSDIS). 

When PCM-objects (building components, PCM composites, PCM in bags, in balls, etc) have to be tested, the measurements can be done with some changes in the T-history set-up and with the in-situ measurement technology. 

Direct determination of surfactants in complex matrices can also be carried out using ion-selective electrodes. Depending on the membranes and additives used, the detergent electrodes are optimized for the detection of anionic surfactants [81], cationic surfactants [82], and even nonionic surfactants [83]. The devices are sensitive to the respective group of surfactants but normally do not exhibit sufficient stability and reproducibility for their use in household appliances. With further optimization of membrane materials, plasticizers and measurement technology, surfactant-selective electrodes offer high potential for future applications.
