In addition the dynamics and precision of measurement can be increased.

However, the dynamic range of measurement is hereby limited by the oscilloscopes used.

During the first design attempts we already considered the difficulties of the dynamic measuring range.

Both techniques have a hugh limitation in terms of amount of sensors, dynamic range or measuring time.

The high measurement dynamics in conjunction with high measurement accuracy and a fast response time result in an application range from leakage detection to operational measurement of consumption.

Whenever high turndown or low pressure losses are important in gas metering applications in any industry, thermal mass flowmeters offer a real alternative to traditional measuring techniques – whether for process control, consumption and supply monitoring, detecting leaks or monitoring distribution networks.

Crucial factors here apart from the integrated interfaces were the high measurement dynamics, very high functionality and simple configuration.

The measurement works equally well in both flow directions and offers very high measuring dynamics.

Due to their small turndown ratio, they usually work in a cascading fashion to cover the wide flow range, thus entailing large pressure losses.

However, the division of the volume flow between the partial gas flow, also referred to as the bypass flow, and the main gas flow may change with respect to the volume flow, thereby reducing the useful measurement dynamics.

Since the largest possible measurement dynamics, the largest possible signal noise ratio, and the linearity of the voltage response to the magnetic field to be measured are of interest, usually an operating point for the ME sensor is selected in the linear range of the magnetostriction characteristic.

Therefore, the objective of the present invention is to improve a device of the type described above in such a way that improved measurement dynamics are obtained.

As a result, the brightness of this illumination can be adapted to the sample or the sensor characteristic for example in an optimum manner, and so a maximum measurement dynamic is achieved for each illumination.

Even when these gas sensors are exposed to exhaust gases having low flow speed, in this way a good measurement dynamic is achieved.

The corresponding quiescent value level, preferably with a reduction for security purposes (according to a multiplication of the quiescent value levels with a factor <1, i.e., a scaled quiescent value level), is subtracted from the signal levels which are proportional to the measured intensities, which subtraction is made for increasing the measuring dynamics and in order to simplify the further processing.

The through-flow meter of the previously known ventilation-mast monitoring system is a conventional device which is limited in its measurement dynamics and, for example, can no longer sense quantitatively if a large quantity of gas escapes through the ventilation mast while the reservoir tank is being filled, because the gas pendulum hose, which serves to recirculate the gas expelled out of the reservoir tank during refuelling into the tanker vehicle, has inadvertently not been connected.

Such a thermal through-flow measuring device has large measurement dynamics, i.e. it is capable of quantitatively sensing a gas volume flow which can vary by several orders of magnitude.

To achieve a robust method, which ensures a highly dynamic measurement of the exhaust gas sensor and does not require any additional structural elements, the exhaust gas flowing to the exhaust gas sensor via the at least one capillary is branched off from the exhaust gas upstream of a stagnation pressure source generating an exhaust gas stagnation pressure. SUMMARY

In these measurement systems, the requirements particularly for measurement precision and dynamic range are very high in the respective processes.

Covering measurement ranges from 0.3 to 75 liters per minute or 0.05 to 10.5 liters per minute at dynamics of 1:250, Bürkert's ultrasonic level transmitters are perfect for recording both small and large flow rates.

In addition to the simple handling and unconditional reliability of FLEXIM's clamp-on ultrasonic technology, users particularly appreciate its exceptional measuring dynamics.

Due to the ultrasonic transit-time technology used, the measurement works bidirectionally with the same high degree of accuracy over an extremely high dynamic range.

The U93 force transducer is at home in production and during all testing tasks, where space requirements, measurement dynamics and simple assembly are important.

These wetted measuring devices have their known weaknesses: They are subject to mechanical wear and tear and only have very low measuring dynamics, i.e. they only measure accurately over a limited range.

In order to carry out measurements in the frequency range, a measuring setup with high measuring dynamics and accuracy is required.

Designing the membrane to be gas-permeable in both directions contributes to a high degree of measurement dynamics.

As a result, a substantial increase in the measuring dynamics can be attained, especially in processes, which can be handled only by relatively low sampling frequency.

To obtain a favourable set-up of the necessary measuring dynamics, the switching network contains, in the first switching stage for the individual high-frequency paths, the above-described preattenuation selectable by the user in 10 dB steps (0 dB, 10 dB, 20 dB, 30 dB) which serves to adjust the attenuation range from the entire path.

This design has a positive effect on the measurement dynamics and consequently also on the switching frequency of the electromagnets 14, 15 that can be achieved with the help of the circuit configuration 44 shown here.
