The pressure gauge consists of three parts, cable connected joint, instrumentation space and damping suite. Wireless remote transimission monitoring system is a ground device, through which downhole pressure and temperature data could be collected, then sent to network at an appointed place by GPRS wireless transmission device mounted on the ground of wellhead.

★Feature
1. High-quality electronic components, military class and lower consumption
-
Pressure sensor: highly accurate and stable, workable at the temperature -35℃～+125℃.
-
Temperature sensor: imported thin film platinum resistor, with good stablity and excellent linearity. It features low measuring temperature error, small thermal drift and fast heat response,eg.: at 100 ℃ working condition, temperature difference lower than 0.5℃, and thermal drift 0.02℃.
2. Humanized test software, powerful function.
3. Suitable for most oilwells operation.
It can highly improve work efficiency, supply timely, accurate and complete oil pool data.
★ Wellhead data acquisition system & data playback system
Downhole data recorded on pressure gauge is transmitted into well head by cable,then strored in data acquisition device. Through GPRS, the data could be transmitted to receiving place(office). From GPRS and computer software, receiving place send data to data center,then forward to customer’s master station.
It supplies accurate and complete oil reservoir data timely. |
