The Multitec® 540/545 is a gas measuring device for analyzing gas mixtures that are formed in biological processes. It can measure the concentration of up to five gases simultaneously (CH4, CO2, O2, H2S, CO). The device is fitted with infrared sensors for measuring methane and carbon dioxide. It can also be fitted with electrochemical sensors.
Device functionality
The use of infrared measuring techniques for methane and carbon dioxide means that there is no possibility of misleading results due to interaction with other gases. This makes it ideal for use in waste disposal sites, sewage plants and Biogas plants. The large display allows all parameters to be displayed simultaneously and quickly read from a single screen. Measurement data is stored in log files and can be transferred without difficulty to a PC over a USB link.

The Multitec BioControl is a combined measuring device consisting of the Multitec BioControl fixed installation and a mobile gas measuring device, namely the Multitec 540/545. Depending on the version of Multitec BioControl, the gas composition and volume can be automatically measured and monitored at up to eight measurement locations. The Multitec 540 measures the values at the individual measurement locations sequentially. The values are transferred to the Multitec Biocontrol via an interface. The mobile gas measuring device must be regularly maintained to guarantee accurate measuring results. The Multitec Biocontrol allows easy maintenance for the versions with four and eight measurement locations as standard, with automatic calibration and adjustment with test gas. The Multitec BioControl fixed installation is non-wearing and low maintenance. All that is required is a regular check for dirt on the flow rate and temperature sensor and cleaning if necessary. This can be done in a few minutes whilst measuring. The mobile Multitec 540 gas measuring device can be easily sent in for servicing. A spare device prevents disruption to operation.

All plant operators producing electricity from biogas, sewage gas or landfill gas aim to optimize processes and thus ensure greater efficiency – in other words, obtain as much methane as possible. At the same time, however, harmful components in the gas need to be kept to a minimum.
Only constant monitoring of the gas composition in a plant can indicate changes in time and thereby prevent prolonged outages. The continuous monitoring of hydrogen sulphide (H S) prevents 2 expensive corrosion damages of the motor by giving an alarm in case of high concentration of H S in the gas. Also the oxygen 2 concentration can be monitored to avoid explosive gas composition in the motor.
If the power generation is subsidised, the plant operator must regularly document the gas composition and volume. The Multitec® BioControl can reliably and sustainably handle all these tasks, though dirt, deposits, moisture, corrosion and fluctuating gas compositions still pose a major challenge.
The Multitec® BioControl can also determine the gas flow rate and the gas temperature. Effects of pressure, temperature, moisture and gas composition are compensated intelligently, which results in a high accuracy of the flow volume measurement.
The Multitec® BioControl is a modular measuring device consisting of the Multitec® BioControl fixed installation and the mobile gas measuring device Multitec® 540 / 545.
Depending on the version of the Multitec® BioControl, the gas composition and volume can be automatically measured and monitored at up to eight measurement locations. The Multitec® 540 monitors the values at the individual measurement locations sequentially. The values are transferred to the Multitec® BioControl via an interface. The Multitec® BioControl allows easy automatic calibration and adjustment with test gas.
The Multitec® BioControl fixed installation is non-wearing and low maintenance. The maintenance is limited to regular check for dust / dirt of the filters and (i.a.) the flow meter and calibration of the mobile device. The mobile Multitec® 540 gas measuring device must be regularly maintained to guarantee accurate measuring results. It can be easily sent in for servicing. A spare device prevents disruption to operation.
