nVision Reference Recorder

Oil & Gas Instrumentation Applications

The oil and gas industry has several critical requirements to the process in order to prevent moisture, corrosion,inefficient fuel usage, and to meet official safety regulations. Differential pressure is one very important factor in measuring gas flow through pipelines,pressure at compressor stations, filter, and many more applications. In addition, deviations in the temperature have great impact on the performance and costs. We specialize in producing calibration and test equipment for use throughout the Oil and Gas Industry. From intrinsically safe digital test gauges and data recorders, to high accuracy dry block temperature calibrators,we have a variety of equipment to help you do your job.

Wellhead Testing – Found both onshore and offshore, wellheads provide the pressure interface for both drilling and production equipment. We provide unmatched accuracy to test and record pressures on the wellhead up to 15 000 psi / 1000 bar. nVision, XP2i

Tubing and Casing Pressure Graphing – To make appropriate adjustments to wells, operators must record a well’s casing and tubing pressure simultaneously. Using our reference recorder, these tests can be completed on the surface, saving both money and time. The nVision can record two pressures simultaneously at up to 10 times per second, and store500,000 readings. nVision

Injected Wells – A pressurized fluid or gas is injected into a well to stimulate production. Operators monitor wellhead pressure and injection pressure simultaneously to optimize flow. The nVision can record two pressures simultaneously at up to 10 times per second, and store500,000 readings. nVision

Chart Recorder Replacement – The nVisionis an excellent replacement for aging chart recorders. It offers higher accuracy in a smaller, lighter, and more robust package, while saving data in an electronic format. It has been suggested that one 10 000 psi nVision could replace most chart recorders, since chart recorders rarely have better than 1psi resolution. nVision, XP2i

Hydrostatic Testing/Leak Testing –Pipelines and tanks are tested for their strength and leaks by pressurizing a liquid, and observing whether there is a pressure loss. Both the XP2i and nVision record the pressure test producing a digital record. Pressure and temperature can be recorded simultaneously by using the nVision. nVision, XP2i

Custody Transfer – When transferring oil& gas from one company to another, accuracy is of the utmost importance.The high accuracy PKII is the de-facto standard used in gas measurement. Then Vision also meets the custody transfer required accuracy of ± 0.025%. Temperature is also an important factor in precise oil flow calculations.The RTC-157, with its active dual zone heating technology, together with a reference probe is capable of accuracy to ± 0.07°F (0.04°C). nVision

Orifice Plate – An orifice plate is used to reduce pressure, restrict flow, or to measure flow. The nVision can measure and record differential pressure at high static pressure directly across an orifice plate. nVision

Pump Testing – The nVision monitors inlet and outlet pressures and records from two pressure sensors, up to 15 000 psi, as fast as10 times per second, to characterize the pump. nVision, ASC-400

Relief Valve and Rupture Disc Testing –Pressure safety valves and rupture discs protect pressure vessels and piping systems from excessive internal pressure. Periodic testing and adjustment of this equipment is essential to maintain overall safety. Our equipment catches the maximum pressure at high speeds (up to 10 readings per second) to complete and document the tests. nVision, XP2i
