How Often Should Flowmeters Be Calibrated?
Ian
Do you encounter issues related to flow measurement accuracy in your plant? We are often faced with questions such as – am I getting correct measurement from this flowmeter? Is it time to calibrate [1] this meter? Did the corrosive application change the calibration factor of my flowmeter? As known very well, ensuring that flowmeters are performing accurately is essential for managing product quality, reducing waste…

Measuring Critical Flow Applications with Vortex Meters
Ian
We are often challenged with competing requirements of containing cost, maintaining uptime and ensuring personnel safety. None more so than critical flow applications involving hazardous fluid. It is a well known fact that preventing unscheduled shutdowns increases overall throughput. This is very difficult in case of critical applications where hazardous process fluids need to be dealt with for replacement or repair…

Measuring Slurry Flow using Magnetic Flowmeters
Ian
Using Magnetic flowmeters for slurry flow can be a tricky thing as the relationship between the flow velocity and the induced voltage is not always exactly proportional. Depending on the slurries types, the resulting noise could present a major challenge causing some to give up on magnetic flowmeter when face with slurry flow. Experienced operators when measuring slurry flow using magnetic meters, will sometimes increase…
