Jerguson

Jerguson – now part of Clark-Reliance Corporation – was introduced to the Norwegian offshore and onshore market by American oil companies that were in the establishment phase on the Norwegian shelf in the 60s. Over these 50 years, the products have been in operation on most installations in Norway, and are increasingly used in the petrochemical industry.

Jerguson offers a wide range of products, including level glasses rated for 690 bar and temperatures up to 316 °C.

The products meet the requirements of Norsok I-001 Rev. 4 and Equinor TR3032. The level gauges are available in most machinable materials in accordance with Norsok M-650.

Through the level glass itself—or sight glass, if you will—you can visually see the liquid level in your tank. In many cases, it is also used as a reference for the other level measurements on the tank.

New design of the “safety ball check valve” for Jerguson sight glasses used for level measurement, which makes it easy to see whether the valve is open or closed and allows the valve to be locked.
