Oil, Gas & Petrochemical
Pressure, level and flow loops on refinery columns, offshore platforms and tank-farm custody-transfer skids need clear material, pressure class and hazardous-area notes. Dwyer requests should name the Ex marking, Zone expectation and output protocol before a transmitter or switch is approved for quotation.
Send a loop sheet
Chemical Process
Corrosion-rated transmitters, ATEX/IECEx-zone instruments and SIS-rated final control elements demand more than a matching range. The media, seal material, enclosure and proof-test expectations must be explicit so the recommendation is not only electrically compatible but safe to install.
Review compatibility
Water & Wastewater
Ultrasonic and electromagnetic flow meters, MID-class water metering and aeration-blower control loops depend on pipe conditions, solids content, grounding, signal output and utility documentation. A practical request includes process data and the metering rule that applies.
Prepare metering details
Power Generation
Steam-cycle pressure and temperature loops, feedwater control and renewable inverter station instrumentation need stability notes, enclosure expectations and calibration records that stay useful during maintenance outages. Dwyer keeps the response tied to the plant condition.
Plan an outage package
Food & Beverage Process
Hygienic 3-A pressure and temperature transmitters with CIP/SIP cycles documented for the audit file require surface, seal, washdown and calibration details. Dwyer requests should name cleaning cycles and certificate expectations before the part is selected.
