Inline monitoring package for an electric submersible pump system

A submersible pumping system comprising:

• a motor;
• a pump driven by the motor;
• a seal section disposed between the pump and the motor;
• a shaft configured to transmit rotation from the motor to the seal section and;
• an inline monitoring package connected between the seal section and the motor, wherein the inline monitoring package comprises at least one sensor and a signal communication device, wherein the at least one sensor measures a parameter internal to or external to the submersible pumping system, and the communication device is contained within a sealed chamber defined within a tubular housing forming part of the inline monitoring package;
• wherein the housing comprises a first end configured for connection to one of the motor, the pump or the seal section, the housing having a second end configured for connection to a different one of the motor, the pump or the seal section, the housing disposed between any two of the pump, the motor and the seal section;
• and
• a removable chassis having a through bore, the through bore having a diameter selected to enable free passage therethrough of the shaft and fluid associated with the shaft, the removable chassis having a first portion disposed inside the tubular housing, the first portion having end plugs sealingly engaged to an interior wall of the tubular housing so as to define a sealed chamber inside the tubular housing and external to the chassis between the end plugs, the removable chassis having a second portion extending exterior to the housing and axially beyond the sealed chamber, the second portion comprising a flow path to allow fluid flow delivered by the pump to flow from exterior of the tubular housing through the second portion of the chassis into the first portion of the chassis to one of the end plugs to cool the sealed chamber and further to flow to the exterior of the tubular housing;
• the at least one sensor and a signal communication device attached to the chassis without potting.

A submersible pumping system, comprising:

• a submersible electric motor;
• a surface-mounted motor controller;
• a power cable extending between the submersible electric motor and the surface-mounted motor controller;
• a pump driven by the electric motor;
• and
• a monitoring package disposed between the pump and the submersible electric motor, wherein the monitoring package includes a shaft for transmitting rotation from the submersible electric motor to the pump, the monitoring package further comprises a sensor array and a sealed chamber containing an electronic processor;
• wherein
• a tubular housing comprising a first end configured for connection to one of the motor, the pump or a seal section, the housing having a second end configured for connection to a different one of the motor, the pump or the seal section, the housing disposed between any two of the pump, the motor and the seal section;
• and
• a removable chassis having a through bore, the through bore having a diameter selected to enable free passage therethrough of the shaft and fluid associated with the shaft, the removable chassis having a first portion disposed inside the tubular housing, the first portion having end plugs sealingly engaged to an interior wall of the tubular housing so as to define a sealed chamber inside the tubular housing and external to the chassis between the end plugs, the removable chassis having a second portion extending exterior to the housing and axially beyond the sealed chamber, the second portion comprising a flow path to allow fluid flow delivered by the pump to flow from exterior of the tubular housing through the second portion of the chassis into the first portion of the chassis to one of the end plugs to cool the sealed chamber and further to flow to the exterior of the tubular housing;
• wherein the sensor array is attached to the chassis without potting.
