Oil & Gas Pressure Instrumentation: A Selection Guide
A pressure transmitter that works fine on a water-treatment skid can fail in weeks on a sour gas wellhead. The reason is not the sensor cell but everything around it: the range, the wetted material, the enclosure rating, and the temperature it sees. If you are specifying pressure instruments for an oil and gas project,…

Differential Pressure Transmitter for Flow Measurement
A differential pressure transmitter is still the flow meter you will find on more lines than any other, and not because it is the most accurate. It is cheap, it is hard to kill, and it works on almost any clean fluid. The catch is that the transmitter does not measure flow at all. A…

Filter Differential Pressure Monitoring: Setpoints & Sizing
A clogging filter shows up as rising differential pressure long before the downstream flow falls off. Measuring that pressure is the easy part. The hard part is choosing the change-out number, then picking a transmitter whose range resolves a nearly clean filter yet still covers a plugged one. A filter trip can be handled by…
