Instrument selection — Density meter for measuring high-solid-content ammonium phosphate phosphoric acid slurries
Thread Content
As the title says. Real-time online measurement of the density of the medium in tanks is required. Concentration: 40%–45% P2O5 ； Density: 1.52～1.56 t/m3 ； N/P: 0.42～0.65:1 ； Operating level: 20%-80% ； Operating temperature: 45～95℃ ； Solid content: 2%-15% ； Main ingredients: phosphoric acid, monoammonium phosphate, water, colorant. The tank is equipped with a stirrer. Please, experts, offer advice on product selection or recommend manufacturers.
If that tank cannot be emptied, a differential pressure level gauge should be installed at the bottom of the tank to maintain the liquid level at a constant value; by utilizing the changes in differential pressure corresponding to this fixed level, the density value can be determined. Today’s differential pressure transmitters have very high precision; the density can be determined with accuracy to three decimal places. With a stirrer already in place, the uniformity of the medium is reliable. Or an insert-type density probe, based on ultrasonic principles, should also be able to provide a relatively accurate measurement.
