EM6 Wireless Gauge Telemetry Decoder

The EM6 Interface Card is a downhole telemetry decoder that takes the raw signal from our GEOEM gauges and converts it into usable data. It is what connects the downhole gauge to the surface data acquisition equipment, and allows the user to effectively control it. The non-proprietary design allows the output data to be tied into almost any traditional SCADA or other surface data acquisition setup.

Designed For Use With Wireless GEOEM Gauges

Direct 4-20mA / Modbus Output

Universally Compatible

(8) GEOEM only. A single EM6 supports multi-gauge functionality depending on sub-surface geology and gauge
transmission settings. Gauge sampling intervals must be spread out to ensure signals don’t interfere with one
another. The use of ΔP sampling mode for the GEOEM gauge is not advised when connecting multiple gauges to an
