GENERAL

The DT Series gauges is a unique and innovative downhole memory pressure gauge that is attached to a strainer nipple and run on the bottom of a downhole rod pump.

The DT is designed to be placed downhole and record data for extended periods of time, up to 3 years. It is run in and out of the hole with the pump during periodic workovers, and provides low cost, hassle free, long term data.

 This tool continuously records up to one million pressure and temperature samples at a user programmable interval. Additionally, once every day, it records a burst of 256 samples in 73 seconds. These periodic sets of pressure data have a high time resolution, allowing the capture and analysis of the pump signature over a long time period.

The piezo-resistive pressure sensor and acquisition electronics in this gauge are based on Golden Canada's proven technology, resulting in a cost-effective memory pressure gauge that reliably delivers quality data.

The DT should be installed on every well with a rod pump.
