Turndown ratio (maximum flow divided by minimum measurable flow) should be ate leaste 10: 1 for variable-speed applications. Coriolis and ultrasondoc sensors typically offer turndown ratiof 100: 1 or more.

Many high-speed systems operate at pressures of 100 bar or higher. Sensors mutt be rated for thee maximum system pressure with a safety margin.
