(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.
The L-Dens 437 E expands the L-Dens 4×7 family of density sensors, which combine an accuracy of 1 × 10–4 g/cm3 with a compact design. The L-Dens 437 E model connects to an evaluation and display unit that calculates several parameters, including density, specific gravity, concentration of various acids and bases, and other units based on density. The evaluation unit also provides Modbus, HART, other bus communications, and 4-20 mA outputs to simplify connection to any flow computer or programmable logic controller.
L-Dens 4×7 density meters have various options for installation. Compression tube fittings, DIN, and ANSI connections are all available as standard, with custom-made connections also possible.
Here are just a few of the possible applications:
• Density measurement
• Concentration measurement of acids and bases
• Mass flow rate determination in combination with a volumetric flow meter
• Product differentiation or phase separation
• Product blending
• Quality control
• Fiscal measurements or custody transfer
