Biocontrol 4 and 8

The premium system for professional process optimisation: economical – versatile – reliable

Multitec® BioControl is the professional system for continuously and automatically measuring and monitoring the volume and composition of gas. It is economical, versatile and reliable. Whether in biogas plants, landfills, sewage treatment plants or composting plants – the unique combination of a stationary unit and mobile gas measuring device enables comprehensive professional process control and optimisation.

The high-quality BioControl 4 or BioControl 8 base station offers extensive and varied measuring options. Developed specifically to meet the requirements of medium-sized to large plants, it stands for process and profit optimisation, maximum reliability and individual flexibility. This premium model is recommended for plant manufacturers with the highest technological demands.

The Multitec® BioControl system comprises the stationary fixed BioControl device and a mobile gas measuring device. Depending on individual requirements, the Multitec® 540 or Multitec® 545 is the most suitable mobile unit. Up to four or even eight measurement locations are available depending on the version (BioControl 4 or BioControl 8). This means that the operator can use any of the up to four or eight measurement locations as a fixed measuring instrument. Alternatively, the Multitec® 540 / Multitec® 545 can perform mobile measurements, e.g. directly at the fermenter, secondary fermenter or even remote units in the plant, and save the measurement values in the BioControl.

Advantages at a glance 

  • Professional, comprehensive and versatile measuring
  • Several motors and desulphurisers can be monitored simultaneously by at least four measuring points
  • Four analog outputs with customer-specific programming for process control (e.g. motor only starts up as of a certain methane concentration)
  • Flowmeter for determining the exact volume of biogas produced in standard cubic metres (Nm3) and calculating the motor efficiency
  • Save time and money whilst ensuring maximum safety by way of continuous automatic measurement
  • Extremely user-friendly and individual configuration
  • Process monitoring and optimisation (e.g. by substrate adjustment)
  • Successfully improve gas quality and increase yield

The BioControl 4 / BioControl 8 and Multitec® 540 / 545 combination is a unique system. Not only does it provide precise information about the gas composition, it also accurately measures and evaluates the volume of gas produced. The efficiency of a biogas plant, landfill, sewage treatment or composting plant can be exactly calculated at any time. For example, when seasonal changes occur in the substrate, you can immediately see how these affect not only the gas quality, but also the volume of gas produced.

Multitec 545

Multi-gas measuring device with infrared sensors and extended measuring range for hydrogen sulphide

With the Multitec 545, up to five gases can be measured simultaneously. The very high H2S concentrations in wastewater treatment plants and palm oil factories, for example, place special demands on the measuring instrument. With its rugged design and wide H2S measuring range, the Multitec 545 is ideal for this use.

The use of infrared measuring techniques for methane and carbon dioxide eliminates the possibility of misleading results due to interaction with other gases. The large screen allows all parameters to be displayed simultaneously and quickly read off at a glance.

Measurement data is stored in log files and can easily be transferred to a PC via a USB connection.

Features
  • Innovative operating concept with jog dial, menu navigation and function keys
  • Large-format matrix display with backlight
  • Selective infrared sensors for hydrocarbons and carbon dioxide
  • EC sensor for hydrogen sulphide with wide measuring range (5000 ppm)
  • Rapid charging in 3 hours
  • Power supplied from four replaceable AA-size rechargeable or disposable batteries
  • Explosion protection: ATEX 100a IIB, IIC when used with leather bag
  • PC communication via USB port
  • Supporting bracket for carrying and positioning

Biocontrol 2


Switch to automated process optimisation and control

The Multitec® BioControl is a unique measuring system comprising a fixedstationary unit and a mobile gas measuring device. It is used in small to medium-sized biogas plants, landfills, wastewater treatment plants and composting plants.

The stationary BioControl 2 automatically monitors and records the gas quality continuously and conveniently at a maximum of two measurement locations. The mobile gas measuring device, either the Multitec® 540 or the Multitec® 545, can also be used to manually calculate measurement values anywhere in a plant. Simply remove it from its docking station and connect it to a measurement location. When it is replaced in the docking station, the protocols are sent to the BioControl 2 and displayed.

With its two fixed measurement inputs, the BioControl 2 meets all the main measuring demands of small to medium-sized plants. For example, it can continuously and reliably monitor the gas quality at the motor and the raw gas composition. The user can individually configure the BioControl 2 to the relevant area of application and demands. The measurement locations and cycles, save intervals, limits and alarm thresholds can be customised according to the application.

The BioControl 2 is non-wearing and low maintenance. It is calibrated and adjusted automatically with test gas (optional). The Multitec® 540 / Multitec® 545 can be easily removed from the docking station and easily posted or transported for servicing. Sewerin can provide a replacement device to allow continued operation without interruption.

The Multitec® BioControl system is user-friendly and can be customised to the operator’s needs; it also offers all the necessary standard functions and a high level of safety. The combination of stationary base unit and mobile gas measuring device thus offers a cost-effective and easy switch to automated process optimisation and control.

Advantages of the Multitec® BioControl system

  • Large, state-of-the-art 4.3” colour touchscreen: easy user-defined settings, language selection
  • Flexible configuration to individual requirements: measurement locations/cylces, save intervals, limits, alarm thresholds
  • User settings can be restored from first day of use (saved on USB stick)
  • Safe, reliable measuring results thanks to self-tests during operation
  • Sturdy and durable: all relevant components resistant to aggressive gases
  • Autonomous and regular saving of all measurement values and settings on USB stick; no data loss, no manual protocols, seamless documentation
  • Comprehensive service: stationary unit largely maintenance-free; fast, first-class support thanks to customer-friendly remote maintenance and diagnostics – anywhere in the world by internet; simple automatic calibration and adjustment using test gas (optional)

Multitec 560

Combined gas warning and measuring device for monitoring processes and personal safety at landfill sites, sewage treatment facilities and biogas plants

The Multitec® 560 is a combined gas warning and measuring device. When used as a gas warning instrument it reliably and automatically detects gases which are toxic and hazardous to humans. When used as a gas measuring device it records and documents the composition of biological process gases.

The intelligent operator guidance optimally supports the user in his work. For example, the device prevents switching between measuring ranges at critical gas concentrations, thus ensuring maximum safety – for humans and equipment.

Applications

The Multitec® 560 is ideal for the preventative inspection of the atmosphere in work areas (e.g. engine pits, silage tanks, shaft constructions). It reliably detects explosive and toxic gases to ensure safety at work at all times.

It is essential to record and analyse the gas composition and optimise processes for the profit-oriented production of biogas. The Multitec® 560 is perfect for these tasks as it uses high-quality infrared measuring technology.
