GAS ANALYSIS
Sustainability through hydrogen technology and emission reduction
At meterQ we place great emphasis on climate protection. Our analyzers are 100% hydrogen capable. At the same time, we offer solutions for bypass emission reduction up to system that work completely without bypass with no negative impact on response time. Our GCs consistently use modern micro and nano technology. The result is a platform that is 4x faster and 20x more sensitive than established technology, while still being smaller lighter and easier to maintain.

Classic gas analysis using new technology: the MGCflex
Our standard PGC for custody transfer measurement of natural gas/hydrogen mixtures is well equipped for every conceivable task in this field up to Ex-Zone 1: Transfer measurement, blending and conditioning plants, biogas, LNG and hydrogen injection, storage facilities.
In addition to billing measurement, the MGCflex is also suitable for mixing tasks, for process control and can even take over limit value monitoring for components such as oxygen due to its short measuring cycles of only 45s and its high sensitivity. Low maintenance and operating costs complete the picture.
Apart from carrier gas, there are no consumables that need to be replaced regularly, such as special filters. Carrier gas consumption can even be reduced if a particularly fast measurement is not required.

Mobility without compromise: the MGCmobile
MGCflex and MGCmobile complement each other perfectly. In terms of measurement technology, both systems are identical. They share a PTB approval in which the MGCmobile is explicitly listed and described as MGCflex‑m. The MGCmobile has been developed for measurement tasks in which mobility is important. This can be a control measurement at any location, for example in a gas composition reconstruction system. The MGCmobile can also be used to check another PGC or to replace it at short notice in case of failure.
MGCmobile is a measurement case that fits in almost any car, can be easily transported by one person, and put into operation in less than two hours. In addition to the measuring case, the system includes a small electronics and supply case and a tripod with the blowers. MGCmobile is of course also designed for use in ATEX Zone 1. The case can be operated with an internal 2 L carrier gas and an internal 2 L calibration gas cylinder or alternatively with externally connected gases.
If the MGCmobile is to run self-sufficiently for extended periods of time, it can be integrated into a small and lightweight trailer that provides space for standard sized gas cylinders, the operating and communication electronics, and even an independent power source. The system is modular, so the case can be removed at any time and used on its own as described above.

Focus on reaction time and emission reduction: the MGCdirect
The robust and compact measuring system of the MGC series allows with the MGCdirect an even more innovative variant than the ones described above: As a transmitter, the MGCdirect is mounted in a small weatherproof box above the tapping point, directly on the pipeline. With about one meter between the analyzer and the gas line, the conditions for a fast response measurement are optimal with the MGCdirect.
A special sampling system is used that feeds gas to the pressure reduction unit and loops unused remainder directly back into the pipeline using a specially designed sample probe. The gas exchange is very fast, and the loop makes it possible to achieve this without a bypass.
With the fast measurement, the short distance, and the special sampling system, the MGCdirect can achieve by far the fastest possible response time. It is therefore ideally suited for all tasks where fast detection of changes in gas quality is essential. Comparing the MGCdirect with an average classically installed PGC, the saved bypass leads to a reduction of emissions by about 95 %!
There are additional advantages compared to a classic installation. A special analysis building or container is no longer necessary. Only the operating gases (carrier gas and calibration gas) need to be installed near the MGCdirect. For indoor installations, a conventional gas supply unit is sufficient. For outdoor installations, a heated cabinet is required and a heated calibration gas line. The need for the usually much longer heated sample gas line is eliminated, however. Only a single Ethernet cable is needed to connect the cabinet to the electrical room. The MGCdirect is therefore usually the cheaper and always the more sustainable alternative to any classic PGC installation.

Continuous calorific value measurement: the MGQflex
When one measurement per second is not enough and a continuous reading is needed, the right solution is the correlative MGQflex. Once you have a true analog and continuous reading like this, it can be directly used to control a gas conditioning/blending system. It can be used for the conditioning of biogas, the mixing of two different gas qualities or any similar task.
The operating principle of the MGQflex is based on the well-known correlation between Calorific Value (Wobbe Index) on the one hand and thermal conductivity and heat capacity on the other. For this purpose, the MGQflex measures the thermal conductivity of the flowing gas sample at different temperatures. To eliminate any possible drift, the instrument calibrates itself automatically at regular intervals using a permanently connected methane cylinder.
MGQflex is significantly less expensive than a PGC, both in terms of purchase and operation. . If only the Calorific Value or the Wobbe Index is of interest, and if you can do without a custody transfer approval and a maximum error smaller than 0.1 %, the MGQflex is the best choice. With the observable increase in fluctuation of the natural gas qualities in the German network, every industrial customer and every operator of gas engines or turbines can benefit from an MGQflex.

Advantages from both worlds: the MGCduo
Because the MGCduo is particularly compact and fast, it can easily be packaged with an MGCflex to take advantage of both systems. Der MGCduo produces continuous analog readings with an uncertainty of < 1 % that can be used for control and a full analysis every 45s that can even be used for custody transfer. < If desired, the MGQ reading can be regularly corrected with the MGC reading.
This system is particularly safe because gas is always measured in parallel using two different measuring principles. Any instrument error becomes immediately apparent and if one of the two systems fail, the respective other will continue to produce usable measurement results.
