Wigersma & Sikkema, founded in 1921, develops, produces and delivers measurement and control equipment for gas distribution. Products include Electronic Volume Conversion Devices (UNIGAS 300), remote reading systems such as dataloggers and modems (UNICOM 300), gas pressure regulators (RS350S) and inspection systems for gas pressure regulating stations (PLEXOR). With these high-tech products, we are the market leader in the Netherlands and are increasingly gaining a foothold internationally. With years of knowledge and experience and our own R&D and production, we can optimally respond to changes in the market, such as hydrogen and green gas. Wigersma & Sikkema is known for quality products, fast delivery and excellent technical service.
KIWA was commissioned by Netbeheer Nederland to investigate whether existing gas pressure regulation stations for natural gas are suitable for the use with 100% hydrogen. The gas pressure regulation station which was tested had an W&S RS350S DN50 regulator built in. The station was equipped with BMA and BDA system couplings to connect the PLEXOR inspection system. A UNIGAS 300 electronic volume converter was used to measure and record pressure, temperature and flow. For several tests, the PLEXOR inspection system was used. The conclusion is that the station can be operated with 100% hydrogen without modification.
