Oil and Gas Production Flowmeters

Major offshore gas producers will normally come across applications where it is necessary to measure the flowrate of produced water . The flowrates of the produced water can be one set of useful information that will assist them in diagnosing the state of their production wells.

The most common type of flowmeter in this application is normally a turbine meter. This can sometimes present problems because of entrained gas pockets that occasionally run through the line and damage inline devices. There may also be some amount of suspended solids. Clamp on flowmeters have traditionally had a bad reputation in these applications because of lack of signal or ultrasonic flow meters not being able to handle amounts of solids or some aeration. EESIFLO 8000 series flowmeters are clamp on explosionproof devices that are rated to ATEX Zone 1. There is no need to cut the pipes, stop the process and most important of all , the units are able to pick up and differentiate between true flow signals and bogus signals. The EESIFLO 8000 series has overcome some of the problems associated with older designed clamp on flowmeters.

The EESIFLO 8000 series can be supplied as a 110 /240 VAC unit or a solar powered 12VDC unit. The applications in the oil and gas industry can include but not limited to the following:

  • Hydrocarbon Liquid Measurement
  • High Pressure Gas Measurement
  • Liquified Natural Gases
  • Liquid Sulphur
  • Bitumen Measurements
  • Methanol Injection Measurements
  • Naptha
  • Crude Oil Measurements
  • Very High Temperature Flow Measurements
  • Low Temperature Measurements
  • Allocation Measurements
  • Wellhead Measurements
  • Pump Protection and Control
  • Crude Oil Sampler Pacing
  • Hydraulic Circuits
  • Oil and Water Mixtures
  • Cooling Tower Balancing
  • Water Cut Determination/Concentration Measurements

Basically any sonically conductive liquid with a known viscosity and density. It is important to know this information so that our electronics will perform Reynolds corrections relating to the flow profile to correct for laminar and turbulent transitions since a different correction factor is applied to ascertain correct volumetric flow rates.

Temperature compensation can also be performed where deemed necessary on more delicate applications and high accuracies comparable to conventional inline meters can be achieved.

The user menu will prompt you for pipeline liquid kinematic visocites ( link to http://www.eesiflo.com/reynolds_number.html)

The following animation gives some idea to the layman on what can be expected in these applications and why it is important for the flowmeter to know both viscosity and density

And the effects on the flow profiles. These calculations are performed automatically within the units once the correct data has been programmed into the EESIFLO 8000 series flowmeter
