what is the difference b/w magnetic flow meter&mass flow
meter? which one is best?
Answer / chandramauli sinha
Electromagnetic flowmeters:
Used to measure all electrically conductive liquids (> 5
µS/cm) with or without solids, e.g. water, wastewater,
sludge, slurries, pastes, acids, alkalis, juices, fruit
pulp, etc.
Used in water/wastewater, chemicals, pharmaceuticals, pulp
and paper, foodstuffs, etc. Electromagnetic flowmeters are
even robust enough to be used in mining.
Mass flow meters:
Virtually all fluids can be measured: cleaning agents and
solvents, fuels, vegetable oils, animal fats, latex,
silicon oils, alcohol, fruit solutions, toothpaste,
vinegar, ketchup, mayonnaise, gases, liquefied gases, etc.
Mass flow, density and temperature (the primary measured
variables) can be used to derive other variables such as
volume flow, solid contents, concentrations, and complex
density functions. i.e. One for all - multivariable
metering.

Valve positioner and actuators in detail.
If a control valve is hunting means means if we are giving 50% to the cv, the cv will open at 51% then slowly slwoly it will reaches 49% , so what to do for solve this problem. The cv is double acting and mounted for anti surge operation, it having 4 nos. volume booster, one sov, one positioner, etc..?

What should be the ideal tapping location for pressure differential transmitter for liquid service. If the tapping taken from the top of the pipe then PDIT will work properly or not. If PDIT do not work properly then what minimum corrective action should be taken in order to solve wrong tapping locations.
