Gas flow and pressure spikes caused by using a plunger to clear the well bore create challenges for wellhead instrumentation.
Pressure gauges are still useful in many applications, and developments can extend their capabilities.
Natural abrasion resistance helps protect against corrosion.
Many differential pressure transmitters are affected by whether the transmitter is oriented in the same plane in the shop as in the actual installation.
Though it is the most common, the design by rule approach may not be the safest.
One of the challenges catalysis researchers face is finding effective fluid control systems that can operate under harsh conditions.
