  • When a pressure transmitter leaves the linearity: the Rosemount Case

    When a Rosemount pressure transmitter experiences the inner silicone oil-loss syndrome, it loses its linear behaviour. In such a case, the response time is not unique; as a consequence, focusing the sensor surveillance to the response time, as required by the technical specifications of the nuclear plant, might have no sense. In which way is the sensor dynamic not linear? Answering this open ...

  • A Multi-Sensor Piezometer for Shallow Marine Sediments in Coastal Environments

    A multi-sensor piezometer has been developed to measure dynamic excess and ambient pore pressures in shallow marine sediments under the effect of surface waves, tides, and currents. The probe consists of a shaft (1.5 m long with five porous stones at subseafloor depths ranging from 0.10 to 0.93 m) and two upper chambers (one that is hermetically sealed for the transducer electronics and another ...

  • Sensor design the key advantage in thermal mass flow meter performance

    Immersible thermal sensors arc finding growing acceptance in the gas flow measurement field. By using two Platinum Resistance Temperature Detectors (PRTDs) immersed in a stream of flowing gas, modern thermal flow meters can directly measure mass flow, without the need for temperature or pressure compensation. Thermal meters offer very high turndown, accu- racy and repeatability at an economical ...

  • Water Level Measurements-Part 1

    Confused about which instrumentation to use in your water level monitoring system? In-Situ offers two categories of pressure sensors for water level measurements: absolute or non-vented sensors, and gauged or vented sensors. They look the same and both measure pressure and water level, but they have drastically different applications, outputs and accuracy. The absolute (or non-vented) water level ...

  • Reducing Costs of Steam Flow Measurement

    Traditionally, steam flow has been measured with a differential pressure device. This is typically an orifice plate. However, such devices are inherently volumetric flow measurements. As we have discussed in previous blog posts, changes in pressure and temperature ...

  • Industrial thermal mass flow meters Pt.1 -Pt.2 - measurement & control

    An industrial thermal mass flowmeter measures either the mass velocity at a point in a flowing gas or the total mass flow rate through a channel or pipe. Figure 1 shows a typical thermal mass flow sensing element. It consists of two sensors: a mass flow sensor and a temperature sensor, which automatically corrects for changes in gas temperature. Both sensors are reference- grade platinum ...

  • Oxygen Monitors for the New Millennium

    Oxygen monitors have become a required piece of safety equipment for many industrial and laboratory environments, where the release of certain toxics can create an area unsafe for living beings (human or animal).  When making a purchasing decision on any oxygen detection monitor, one need look no further than the sensor cell found at the heart of the monitor.  While each oxygen ...

  • Wastewater Level Measurement Techniques

    Level monitoring and control is a fundamental requirement in any wastewater treatment process. You will find level instrumentation installed at even the simplest treatment plants for pump control, chemical storage tanks and process level controls or alarms. Operators have only limited or emergency control over treatment plant influent, so level controls and instrumentation play an important role ...
