    The sensor node consists of a) swappable sensors such as strain gages and temperature sensors, and b) data acquisition platform, microprocessor and wireless data transmission (mote platform). The prototype WSN was originally conceived for high speed measurements (such as hydraulic pressure transients and vibrations) that require higher bandwidths than other systems used for environmental monitoring (e.g. Mainwaring 2002).
  • ISA FUND TST MEAS INSTA - Fundamentals of Test Measurement Instrumentation
    Most electrical and electronic-based systems use copper wiring as a means of transferring measurement informa- tion while other systems can use pneumatic, hydraulic , optical, or wireless transmission. In its simplest form, such as a pressure gauge , the components of a test measurement system are all contained within the same device.
  • Wireless Retrofit Solutions to Replace Failed Permanent Downhole Gauges: Case Study in a Gas Well
    The hydraulic actuator does not hold pressure and as this bleeds off spring force is used to return the piston to the flowing position. Figure 2 : a) Wireless Gauge assembly: b) flow through gauge for pulse creation .

  • Real-Time Wireless Sensor Network for Landslide Detection
    When the rainfall intensity is larger than the slope saturated hydraulic conductivity, runoff occurs [7]. The geophysical sensors selected for the in-situ measurements are pore pressure transducers, soil moisture sensors, geophones, stain gauges and tiltmeters, based on their relevance in finding the causative geological factors for inducing landslides under heavy rainfall conditions. However, commercially available wireless sensor nodes do not have implanted geophysical sensors and this constraint has lead …
  • Surface Control System Design for Remote Wireless Operations of Intelligent Well Completion System: Case Study
    The energy stored into the hydraulic accumulator and delivered between a 5000 psi and 3000 psi pressure interval is enough to operate the well for a fifteen (15) step operations of the ICVs, power the downhole gauges and well communication systems. The in-field communication infrastructure is a wireless radio network provided while the communication network between the …
