The Still Pipe Gauge, RTG 3950 The Still Pipe Gauge is used on tanks with still pipes and with all products suited for still pipes.

The gauge uses a low-loss radar propagation mode which virtually eliminates the influence of the still pipe condition. Measurement is made with highest accuracy even when the pipe is old, rusty and cov- ered with deposits.

The Still Pipe Gauge fits 5”, 6", 8", 10" and 12" pipes. It can be mounted on an existing still pipe and there is no need to take the tank out of opera- tion during installation.

There are two versions of RTG 3950: fixed and inclined. The inclined ver- sion has a hinged hatch, enabling full pipe size product sampling or verifi- cation hand-dips.

The LPG/LNG Gauge, RTG 3960

The RTG 3960 is designed for level measurements in LPG and LNG tanks. A 4” still pipe is used as a wave guide for the measurement and prevents a wavy or boiling surface from disturbing the measurement. Radar signals are transmitted inside the pipe towards the surface.

The pressure sealing is a quarts win- dow approved for use in pressure vessels. As standard the gauge is also equipped with a fire-proof block valve and a vapor space pressure sensor.

The LPG/LNG Gauge is available in two versions, a 150 PSI version and a 300 PSI version.

The reference pin function enables verification of measurement without opening the tank. By setting the gauge into “test mode” the measured distances are compared with the actual distances.
