HighPressureLine for High Pressure Level Measurement up to 200 bar
The HighPressureLine is the standard for operating pressures from 50 bar to 200 bar and operating temperatures up to 400°C. While many manufacturers can only offer special productions in the high pressure range, WEKA feels particularly at home in this segment and offers four staggered series (80/100/150/200 bar) as standard.
Explore the technical specifications of the HighPressureLine for your demanding high pressure applications.
HighPressureLine

Proven Spherical Float Technology for Highest Pressures
WEKA was the first manufacturer to develop the spherical float. Due to the optimally pressure-resistant spherical geometry, a titanium float could be designed that is suitable for highest pressures without increasing internal pressure. This high pressure level measurement according to European PED or American ANSI/ASME standards ensures long-term delivery availability.
EN and ANSI connections are included as standard in all four pressure ratings. Simple pressure-temperature diagrams allow determination of the basic type including connections. The proven material group 316/316L ensures optimal material compatibility.
Additional tests such as X-ray or dye penetrant inspections are possible and common. Surface finishing and test certificates up to EN10204-3.1 ensure highest quality standards.
