Oil & Gas

Variety of Reliable Options

  • Flow meters
  • Filter monitors
  • Differential pressure level indicators

Orange Research differential pressure and flow instruments meet the requirements of dozens of critical applications within the oil and gas industry. We are the leader in differential pressure gauges, switches and transmitters where lower cost solutions are required. Our accuracy (2%) is better suited to filter, level and flow requirements – especially considering other manufacturers’ higher accuracy levels – which add about $700-1000 to the price!


Indicators for All Stages of Oil & Gas Market

  • Exploration
  • Production
  • Refining
  • Petrochemical
  • Upstream & downstream – including storage and transportation

Why Orange Pressure & Flow Meter Indicators?

  • Rugged, reliable design is housed in machined metal
  • Frictionless design has no mechanical linkage to fail
  • Widest variety of configurations to match all requirements
  • Normal and hazardous locations

We look forward to working with you in designing a differential pressure or flow monitor for your specific needs.

Oil & Gas Filter Monitors

Our differential pressure instruments monitor the liquid or gas filter condition and indicate when it’s time to service the filter. Designed for medium or high pressure filtration applications, the pressure bodies handle up to 10,000psi on some models, which satisfies many offshore filter system requirements.

They are popular on particulate and backwash filters, along with coalescers and liquid separators. High temperature models handle up to 450F.


Level Indicators

Oil, water and chemicals housed in a variety of tanks and vessels require level monitoring. Connect the high pressure port to the bottom of the tank and vent the low pressure port to atmosphere for a low cost, reliable level monitor. The gauge simply measures a column of liquid.

Oil & Gas Flow Meter Measurement

The most popular method of measuring flow uses differential pressure. Measuring the pressure drop across an orifice plate or venturi allows for a low cost flow meter design. For larger pipes in-line flow meters can be cost prohibitive.
