CBM Downhole Pressure Gauge

The downhole pressure gauge is the most important gauge to measure reservoir parameters. It can accurately read the reservoir pressure and temperature.

According to the requirements of CBM drainage and mining, downhole pressure gauges and frequency control cabinets should form a liquid level control automation system, which can adjust rotary speed automatically up to the liquid level. Thus gradually achieving fine drainage and mining targets.
