Flow rate from supplying gas lights to street lights
Gas pressure regulation station

Ca. 40 mbar
+5 … 40 °C
The streets in Düsseldorf are illuminated with electrical lights and gas lights. Each gas light’s supply comes from gas pipes from gas pressure throttling stations. The lights are ignited by a defined pressure surge which has a defined pressure level and flow rate. This flow rate can be measured and monitored with Höntzsch measuring instruments. It’s the only way to guarantee a safe ignition process.
Tried and tested
Since 2006 Höntzsch vane wheel sensors type ZS25 have been used in this application
The sensor’s very low measuring uncertainty ensures reliable set-up of the gas lights and therefore the lighting.
The used measuring technology also contributes to the preservation of the historical cityscape with gas lights.
