    Non-Nuclear Density Meter For Slurry

    There is a company called Industrial Tomography Systems (ITS) that just introduced a non-nuclear densitometer. According to ITS, it is a technology designed around electrical conductivity. The DENS-ITOMETER monitors slurry flow across an entire cross section and provides accurate, real-time...

    What Thermocouple Types have you used for temperature control?

    The simplest way to understand the different type of thermocouple is by their range of measurement and sensitivity. Type J has a range of minus 40 °C to +750 °C and sensitivity of about 50 °C Type K has sensitivity of approximately 41 °C. Measurement range is minus 200 °C to +1350 °C /...

    Electromagnetic Flowmeter Fluctuations

    Another possibility is that the location of the meter where it is installed in the flow line. Typically, a magnetic flow meter requires that the inflow of the fluid is in a straight pipe that is 10x its diameter. The outflow has to be a straight pipe of 5 x the meter diameter. This is to avoid...
