Replacing a Chart Recorder

A chart recorder is an instrument that creates a paper chart record of the pressure in a system.  It relies on ink pens mounted on mechanical arms, which pivot in response to pressure.  Its primary advantage is an ability to record for extended periods in remote locations. An experienced user may provide preliminary analysis on the chart output in the field, but communicating or storing the data electronically becomes possible only after a technician enters or scans the chart into a computer.  This process can take days before results become available. Chart recorders…Read more

Application Stories!

Much of what we do here at Cameron Instruments is linked to our customer's success with our products.  For this reason we decided to run an "Application Stories" promotion, to hear from our customers how the products are working for them and where they are being used.  We heard from many people, and below are a couple selections from those submissions. The first story comes from Swagelok Central Canada, which is owned and operated by Winnipeg Fluid System Technologies Ltd.  Since 1970 they have been providing the Canadian Prairies and NW Ontario with…Read more

Pressure Safety Valve Testing with the XP2i

A pressure safety valve (PSV) protects vessels and piping systems from excessive internal pressure.  When a system reaches a predetermined pressure the PSV opens, a portion of the media discharges, and the pressure inside drops to a safe limit.  Once the pressure reaches the valve's reseating set point, the valve closes.  Periodic testing and adjustment of pressure safety valves is essential to maintain overall safety in Oil & Gas, Power Generation, Water/Wastewater, Aerospace/Aviation, Chemical/Plastics, Steel Manufacturing, and may other industries.  The most common test method for safety valves and relief valves is a…Read more

Is Your Pressure Pump Really Leaking?

Archimedes-born in 287 BC - was a practical man and took full advantage of Laws and the repeatable behavior of Physics.  He invented a variety of machinery including a screw pumping device that lifted water from a river to irrigate field crops.  Today we employ the same laws and engineering to manufacture a variety of pumps for many different applications.  All of these pumps make life easier and surely Archimedes would approve.  Regardless of the type, under some circumstances they still leak or appear to leak, what can we do about it? The…Read more
Reference Recorders:  The Future of Pressure Measurement

Reference Recorders: The Future of Pressure Measurement

Within the pressure measurement industry, relentless innovation has become the norm.  New technology continually supplants the old.  In other technology spheres, PCs pushed aside typewriters.  Cell phones drove out telephones.  And today, reference recorders are shaking up old standards in the oil & gas industry. A reference recorder is a new class of instrument that is gaining ground over other common pressure instruments.  Chart recorders, deadweight testers, and analog pressure gauges all brought several advantages in their time.  Increasingly, reference recorders replace all three with a single instrument. What is a Reference Recorder?                                                                                                               …Read more

What you need to know about Pressure Gauge Calibration

To start off our discussion of calibration and its importance we should first start with a clear definition.  Calibration is a comparison between measurements - one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible and with a second device.  The device with the known or assigned accuracy is called the standard.  The second device is the unit under test.  There are a couple of different methods of collecting calibration data; Cardinal Point Calibration and, Nominal Point Calibration.  For the…Read more
