A data monitoring system includes a display unit for communicating with an operation that has characteristics which are to be monitored, a recording unit located remotely from the environment of the monitored operation, and a local area network interconnect circuit for connecting the display and recording units. The local area network circuit allows multiple display units to be connected to a single pair of electrical conductors. Each display unit has at least one dual microcomputer configuration interconnected by a shared dual port random access memory. A third microcomputer is located in the recording unit for communicating over the local area network circuit with one of the microcomputers in the display unit.

A rheology test system includes a self-propelled vehicle, a computer contained in the vehicle and a rheology flow loop skid mounted in an outboard storage compartment of the vehicle. The rheology flow loop skid includes an obliquely mounted helical conduit through which laminar flow is maintained. The helical loop is mounted on a base near an inboard side thereof, and instrumentation is mounted on an outboard side of the base so that the apparatus can be readily used while mounted on the vehicle. Improved connecting pipes provide a more compact construction and a more easily assemblable and disassemblable construction.
