Derive and calculate

The gasQS static precisely determines heat conductivity using a microthermal sensor. For binary gas mixtures (e.g. biogas), it can derive the percentage of the gases as well as calculate various gas properties such as calorific value and density with high accuracy.

  • Simple integration into the control system
  • Only minimal interventions into the pipe system and no exhaust line required

Binary gas mixtures

A binary gas mixture (BG) is a mixture of two components such as methane and carbon dioxide. These are often found in applications with biogas plants.

Our gasQS measuring device offers various uses in gas burner applications: regulation of the fuel entry, measurement of key figures and optimization of the combustion processes.

Biogas plants

Biogas plants are becoming more  important for energy generation. With our measuring device, the processes can be controlled and monitored and the CH4 content in the gas can be measured.

P2G & methanation

Our measuring device is ideal for the regulation and monitoring of methanation processes. Additionally, it can be used to determine the purity of hydrogen.

Fuel cells

Whether for automatic fuel and air feed regulation, increasing effectiveness or extending lifespan - the gasQS technology leads to increased efficiency.

How often should one perform a calibration check on the gasQS™ static?

The gasQS static as a process instrument experiences wear from the conditions of the process in which it is installed. Temperature cycles, electronic component tolerance shift including the sensor chip and contamination build up over time on the sensor chip will all contribute to affecting the accuracy of the instrument. It should therefore regularly undergo, at a minimum, a calibration check if not a recalibration. But how often?

gasQS static does not have specified due dates for calibration. Mems AG designed the device from the very beginning in such a way that the above influences have the smallest possible effect on the long-term behavior of the sensor.

The entrance to the measuring chamber is protected by a double-mesh filter against the entry of dirt particles. The chip sensor has passed its long-term test in several million passenger cars as a mass flow meter of the intake air, but also in household gas meters, over more than 6 years, no reduction in performance of the sensor could be detected. When installed correctly, i.e. in upside-down position, no contamination of the chip, which would impair its function, is to be expected even in long-term operation with non-condensing gases. All electronic components meet the requirements of the strict standards of the automotive industry, so no premature aging effects should occur from this side either.

Mems suggests that gasQS static undergoes a calibration check every two years. However, based on the application conditions, and perhaps company quality procedures, each customer must determine when they need to send in an instrument for recalibration.

The easiest way to check is to use one of the gases listed on the "Calibration Documentation" to compare the measured values obtained with those of the initial test. If this is not possible, Mems is happy to take on this task for its customers.
