Pumps are used throughout field operations for moving drilling fluids, crude oil and produced water. The gas compression process increases natural gas pressure to facilitate pipeline transport. Flow switches monitor product streams to signal no-flow/low-flow conditions caused by plugging or valve closures, and provide a defense against pump cavitation. A shut down system can also be actuated.
Depending upon power availability, mechanical or electronic flow switches provide protection for compressor skids. Solid-state switches provide the highest level of pump protection by offering low flow sensitivity, wide temperature operation and high turndown.
