Oil & Gas
EMCO Controls has supplied to the Oil & Gas industry since the beginning of 1980.
To document the quality of our instruments is becoming increasingly important. We are able to meet the most stringent requirements from our customers. These requirements may include: full material traceability for material from approved steel makers with QTR, NACE certificate for our service, PMI certificate, material certificate according to EN 10204-3.1 and full coating procedure.
Test documents may include: full NDT of weldings, Dye Penetrant Test of material, pressure test and coating examination, all performed by certified operators.
We have a quality system certified according to ISO 9001: 2008. As welding is an important part of the instrument, we are also certified according to EN 3834-2. We are certified according to the Pressure Equipment Directive PED 23/97 EC Module H. We also hold a quality certificate issued by Achilles and Sellihca.
DP flow is one of the most studied and best understood flow technologies due to its simplicity and importance. This bare bone technology is worldwide accepted and supported by millions of successful installations. Instrument companies are continuing to bring out new and improved transmitters, including multi variable transmitters, supporting and extending the utility of DP flow.
DP flow meters
The main type of flow meters for gas and liquid is the FLEMCO type, and for the steam it is the STEEMCO type. They are mounted between flanges from DN 50 to DN 400. All types have a 4-20 mA analogue output signal, but also have the possibility of serial communication with HART.
Above DP flow meters are for volumetric flow. Models for mass flow for gas and saturated and superheated steam are available.
Venturis and Nozzles
Classical venturi tubes are manufactured in 3 different versions: machined, welded sheet, and as cast. Process connections are flanges, butt weld ends or hubs for clamp connections. With single pressure tappings or annular rings.
For high pressure and temperature applications. Widely used for steam flow measurement. Supplied in materials including 13CrMo4-5, 10CrMo9-10 and F91. The ISA 1932 nozzle with single pressure tappings or annular chambers offers higher accuracy but also has higher pressure loss than the venturi nozzle.
Averaging pitot tube
For flow measurement of liquid, steam and gasses. The averaging pitot tube is mounted diametically across the pipe. The probe of the averaging pitot tube has holes spaced centrally within concentric rings of equal areas. Sizes from DN 50 (2") to DN 8000 (320") and pressure ratings up to PN 400 (2500 lbs). It has a flange mounting style for easy and correct mounting. The averaging pitot tube is manufactured from solid bar in a great variety of mechanicable materials reaching from stainless steel to Hastelloy, 254 SMO, Inconel, Titanium and Duplex steel. Simple construction but still strong and ridged for highflow velocities and high differential pressures. Models are available as retractable under pressure.
Sight Flow Indicator
Emco Sight Flow Indicators type EFG are used for locally checking the liquid flow passing in pipelines. The Emco Sight Flow Indicator has a double glass construction - a look through design. The sight glass is toughened or borosilicate glass depending on operating temperature. The flow indicator is made from bar stock material and therefore available in all machinable materials.
