Measuring-gas input:
The length of the biogas pipe should not exceed 50m. Stop valves should be installed at the sampling points of the biogas plant in
order to prevent biogas from escaping when the measuring-gas hoses are disconnected. The measuring-gas pipe should, if possible,
slope towards the sampling point, so that any condensate produced can flow back into the process. The pipes must, on all accounts,
be definitely protected against frost.
If the measuring-gas inlet of measuring point 1 is not fitted with an internal stop valve (option), the customer is responsible for
installing a stop valve in the case of admission pressures of more than 5 hPa in order to close the inlet during longer measuring
breaks.
In order to protect the biogas plant against flashback, a safety unit is installed at the measuring-gas input of the analyzer which
prevents flashback into the gas-carrying system of the plant in the case of pipe leakage. The device is at present fitted with the F 510
detonation protection system according to EN 12874 / PTB 02 ATEX 4012X. Its gas connection is identical to the other screw-type
connections.
Exhaust air pipes:
Make sure that the length of the exhaust air pipes does not exceed 5 m in each case in order to ensure almost pressureless
discharging of the measuring gas. The exhaust air pipes must extend separately into the open. Make sure that the pipes are laid in
such a manner that they are protected against frost and that the outlets cannot freeze.
The exhaust air contains biogas that generates a flammable gas mixture with air oxygen!
Make sure that this does not cause any hazards!
Condensate pipe:
The condensate produced during gas processing must be directed through a hose into a suitable collecting tank, and must be
disposed of in accordance with the applicable laws and regulations. Make sure that the condensate pipe and the collecting tank
cannot freeze.
Important - aggressive condensate is possible!
Therefore proceed with care when handling condensate, and wear appropriate protective clothing.
Installation of the system is now complete, and the system can be set into operation as described in section 6.
