  • Ferrous Wear Metal Measurement Made Easy with the FerroCheck

    Historically, one of the most cost-effective indicators of machinery health has been the analysis of ferrous debris in oil. Such analysis utilizes the ferromagnetic properties of generated debris to perform the analysis. Since nearly all wear debris contains ferrous material (in particular iron), an abnormal increase in the amount of debris can be directly correlated to abnormal machinery ...

  • Open Channel Flow - The use of Level sensors for open channel flow measurement

    Open Channel Flow - The use of Level sensors for open channel flow measurement Level sensors from SolidAT are implemented in Open Channel Flow applications. In these types of applications, the level sensor is installed above a special water flow structure and accurately measures level of flowing water or wastewater. The sensor then calculates flow through the structure ...

  • Online discharge measurement with horizontal doppler-flow sensor

    Background The regional authority responsible for the barrages in the Free State of Saxony is in charge of the water management of the Rötha. Reservoir. This reservoir is situated close to the river Pleiße, from which the water is led over a weir into the reservoir.. Knowledge about the inflows of the reservoir is important for the water management there. So far, the ...

  • 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 ...

  • Wastewater engineers go with the flow

    The efficiency of maintenance work has been improved by water treatment engineers employing Intellisonde monitors in their final effluent. Designed primarily to measure water quality, the Intellisondes also measure flow, and this reading is being used to detect the accumulation of debris that necessitates a maintenance visit. Wastewater treatment efficiency is often measured by the analysis of ...

  • Typical Sensor Location Considerations

    The sensor mounting location within a space may be dependent on many variables. There are no specific formulas since each application will have it’s own determining factors and priorities. These include, but are not limited to: source of gas: Is the source a combustion exhaust from a vehicle or furnace or a vapour from a tank spill, pipe leak, or faulty valve? density of ...

  • Online flow measurement

    Background The undershoot weir in Hohensaaten was built in 1913. It has three openings and regulates the discharge from the Oderbruch and from the Finow canal into the Hohensaaten-Friedrichsthaler-waterway. Moreover, it protects parts of the Oderbruch against Oder floods. The weir controls the waterlevels in the Havel-Oder-waterway and in the reach of Niederfinow- Hohensaaten. ...

  • Sensor Probe Insertion/Retractor Simplifies Installation of Steam Flow Meters in Hot Tapping Applications

    Accurately measuring fluid flows like steam in large ducts or pipes is a challenging application. Large ducts and pipes often have swirl or turbulent flow which makes accurate flow measurement difficult. Not to mention, installation of steam flow meters can be extremely challenging since in many cases you will need to shut off the steam flow to install the meter. This is just not ...
