01 Β· Performance

Performance Data

Wide flow range from 0.5 L/H to 1,50,000 L/H, pressure up to 300 Bar, independent of viscosity, high resolution, pulsation-free measurement, non-sensitive to pulsating flows, and resistant to corrosion by advanced materials and bearings.

02 Β· Where it's used

Markets & Areas of Application

Light and heavy fuel oils, hydraulics test rigs with varying viscosities and fluids β€” an excellent choice for laminating systems, painting systems, adhesive dispense systems, and batching systems. Aluminum wetted parts suit kerosene, gasoline, diesel, light and heavy oil. Stainless steel wetted parts suit wine, beer, alcohol, milk and food liquid. PPS wetted parts suit chemical and pharma drug applications.
