Proof Testing Level Measurement Devices
Jim Cahill
Safety instrumented systems (SIS) include the sensor(s), final control element(s) and logic solver(s) for each of the safety instrumented functions (SIFs) in the SIS. To verify the SIFs are performing the amount of risk reduction intended for their application, they must be periodically proof tested. PCN Europe magazine interviewed Emerson’s Teddy Tzegazeab on how proof testing has changed for SIFs with liquid level…

Continuous Emissions Monitoring for Energy Optimization
Jim Cahill
For process manufacturers, the energy bill can up to 40-60% of the total operating budget. One way to optimize the energy expended is with Continuous Emissions Monitoring Systems (CEMS) . Many people think of CEMS as something used for emissions regulatory reporting to help ensure certification and compliance with local and international regulatory agencies. But these systems can also be used in helping to increase…

Moving Beyond Local Pressure Gauge Readings
Jim Cahill
Walk around most any industrial process manufacturing or production process and you’ll likely see pressure gauges providing feedback to operators who walk by. According to the Pressure Gauge entry in Encyclopedia.com , this technology: …was invented by French industrialist Eugene Bourdon in 1849. It utilizes a curved tube design as the pressure sensing element. A less common pressure element design is the diaphragm…

What good is a safety level measurement if you can’t trust it?
Peta Glenister
What good is a safety level measurement if you can’t trust it? A coal fired power plant installed an electronic gauging system for both level indication and level alarms on their plant’s steam drums. The system was configured to give Hi and Hi-Hi alarms and to shut down the boiler in case of emergency. However, within two years of operation they experienced leaking electrodes, and some of these leaks then caused false…

Level Sensor Safety Proof Testing
Jim Cahill
Backing up your computer or server is a waste of time if restoring the backup fails when you need it. Good practice is to test these backups on separate test systems periodically to make sure they restore properly. Similarly, safety instrumented systems (SISs) need to assure that each safety instrumented function (SIF)/safety loop does what it’s intended to do to bring the plant to a safe state in the event of a demand…

Remote Partial Proof Testing Level Sensors
Jim Cahill
For safety instrumented functions (SIFs), proof testing is the process of identifying undetected dangerous failures in the sensor, final control element and logic solver which comprise the SIF. Dangerous failures are those that could put the safety instrumented system (SIS) in a hazardous or fail-to-function state. If undetected, in the case of level measurements, this could lead to an overfill and spill, with potentially…

Using Flushing/Drip/Calibration Rings in Pressure and Level Measurements
Jim Cahill
If you work with pressure measurement instrumentation, you may have heard the phrases drip rings, flushing rings or calibration rings. These are used for pressure and differential pressure (DP) level measurement devices where diaphragm seals are used. I bring this up because I received an email recently that asked about these [edited and paraphrased to protect confidentiality]: Can you advise where in the Emerson…
