Downhole pressure gauge, PPS 51 - Short Memory Gauge

PPS 51 - Short Memory Gauge

The PPS51 gauge is designed for applications with length limitations. The most common usage is for building this gauge into other downhole tools, such as water injection and plunger lift equipment. It is also used for general pressure survey for gradient or build up tests. The gauge length is only 4.8 inches, including one half AA lithium battery pack.
