M6 Downhole Gauge Telemetry Decoder

The M6 Interface Card is a downhole telemetry decoder that takes the raw signal from the downhole gauge and converts it into usable data. When used with our ESP Mini gauge and corresponding surface choke, or our GEOHV gauges, the M6 Interface Card connects the downhole tool to the surface data acquisition equipment. The non-proprietary design allows the output data to be tied into almost any traditional SCADA or other surface data acquisition setup.

Technical Specifications

LED Lights

The LED lights on the M6 gauge controller indicate the various status of the interface card that is useful for verifying operation and easy troubleshooting. These three lights help users quickly authenticate the raw signal received from the downhole gauge, the successful delivery of a full data packet, and the successful delivery of RS485 Modbus data.

M6 Interface Card Setup

Below is a diagram showing how the M6 Interface card integrates into a surface data aquisition setup when used with either an ESP Mini or GEOHV gauge. The 3 Phase Modular ESP Choke or the GEOHV Line Filter provides voltage protection and signal filtering before the raw signal is interpreted by the M6.
