|
Electronic Controller Card |
Given that the conductivity is the inverse of the resistivity, provisions are provided to inverse the resistivity sensor readings which enables checking of the conductivity sensor. This provision is also possible with the conductivity sensor. Having two sensors ensures high accuracy and sensitivity for the entire measured range.
PVT v2.0
The new version of the PVT assembly has now been released for
sale after testing. This provides a reliable, safe sampling method for up
to 2 x 524.4cc formation fluid samples per run. The sample chambers have
been designed with an operating pressure of 10000psi,and tested to 15000psi.
They conform to NACE sour gas standards and the design has been ratified by a
third party Mechanical Engineering workshop.
