Hermann Sewerin GmbH products

The entry-level model for automated gas analysis supporting process optimisation. The Multitec BioControl is a unique measuring system comprising a fixed stationary 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 premium system for gas analysis and volume measuring supporting professional process optimisation. 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.

Combination measuring devices for gas supply with integrated ethane detector. Products from the EX-TEC HS family combine ergonomics with cutting edge technology. Thanks to its innovative design this range offers the user the right instrument for each different application. All appliances from the EX-TEC HS family meet the requirements of DVGW Code of Practice 465-4 (German Technical and Scientific Association for Gas and Water).

Flame ionisation detectors for inspecting underground gas lines. The PORTAFID M3K portable gas detector is the perfect tool for above-ground inspections of underground gas lines. It is reliable and highly accurate, resistant to interference from moisture and only responds selectively to hydrocarbons. The PORTAFID M3K features an 0.4 l fuel gas bottle, which is carried separately on the user`s back.

The specialist for leak detection with tracer gas and hydrogen. The VARIOTEC 460 Tracergas was developed especially for leak detection on underground pipes by using tracer gas. It is characterised by an outstanding price to performance ratio.

Cost-effective combination measuring devices for gas supply. The VARIOTEC 480 EX devices from SEWERIN with their intuitive controls enable users to work efficiently and cost-effectively. The VARIOTEC 480 EX family covers almost all common gas measurement applications in the gas supply branch. Models 480 EX and 460 EX can be optionally fitted with a detector for ethane analysis to help you safely distinguish between natural gas and swamp gas. All devices can also be individually fitted with electrochemical sensors. The VARIOTEC 480 EX family integrates seamlessly into the SEWERIN product range, so existing accessories can still be used.

Vehicle-based solution for the network inspection of underground gas pipes:economical – laser-based – fully automatic. The LaserGasPatroller is a vehicle-based solution for the economical network inspection of underground gas pipes. Gas leaks are detected when the laser-based measuring system LGP 800 is driven over the gas pipes. The LGP 800 is operated by the SeCuRi SAT software system. SeCuRi SAT is the world`s most sophisticated documentation system for pipe network inspection.

The intelligent network patrol for maximum safety of networks. A leakplotter vehicle basically consists of the following components: the suction unit with bells for collecting samples, the measuring technology with FID and oxidiser, the notebook with the software controlled operating and documentation unit, and the option for GPS documentation along with the test set for automatic adjustments. These components are built into the vehicle.

Detecting, measuring and warning - Everything you need. Portable gas concentration measuring device for detecting, measuring and warning. The mobile gas measuring and gas warning devices from the EX-TEC PM 5xx series make the everyday work of gas fitters, maintenance staff and other technical staff easier. They can be used to locate leaks in freely accessible gas pipes, assess the risk of explosion and determine whether toxic gases are within the occupational exposure limits (OEL). In the Structure application, the EX-TEC PM 580 displays the carbon monoxide concentration in the room air and triggers an audible and visual alarm if the values are too high. Toxic carbon monoxide is produced by combustion equipment, such as heating systems, as a result of insufficient ventilation and poses a risk to humans.
