Pressure Gauge

Innovative pressure gauge, crucial for process safety.

Product description

According to the ASME code and regulations, the space between the rupture disk and the safety valve must be provided with a pressure gauge or suitable tell-tale. In addition, the ASME code for double discs requires the use of a tell-tale in places.

Our Tel-Tale pressure gauge is a “telltale” also known as the “gauge with drag indicator”. It indicates pressure increases using a “telltale” that stays at the level of the highest pressure reached, even when the pressure subsequently decreases.

The advantage of this is that it shows operators when there has been a pressure rise, even if the pressure rise was not observed at the time. In contrast, the indicator on traditional pressure gauges returns to zero when the pressure returns to zero, meaning that pressure rises can go unnoticed.

Tel-Tale is therefore an ideal solution for applications where safety-critical measures are needed to prevent undetected pressure rises between the rupture disc and valve inlet.
