Sewage Gas or Digester Gas

Normally the Sewage gas or Digester gas contains Elemets, which makes the Life of a mechanical Meter very short. Thermal Massflowmeter have no moved parts into the pipe and therefore a small pressure drop results. Flexible electrical Ports makes the Datakommunication with your PLC-System easy.

After 15 years industrial operation without any problems, we have a real strong reputation and the best references of our client (Sewage Plants in Switzerland).
