(Anton Paar: Ashland, VA) -- Anton Paar, developer and manufacturer of measuring and analysis instruments, has expanded the L-Dens 4×7 portfolio of process density meters by releasing the L-Dens 437 E. The system measures density by determining the frequency of an oscillating u-tube made of hastelloy, the corrosion-resistant alloy widely used by the chemical processing industries. The excellent chemical resistance of hastelloy makes the meter ideal for aggressive applications in the chemical industry. The new L-Dens 437 E is cost efficient, accurate, compact and has a variety of process connections available.
