New Anton Paar Process Density Meter Released for Chemical Industry

Share Article

Anton Paar has released the L-Dens 437 E process density meter. The system uses a Hastelloy oscillating u-tube, which is ideal for applications in the chemical industry.

L-Dens 437 E Density Sensor

Anton Paar has expanded the L-Dens 4x7 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 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 4x7 family of density sensors, which combine an accuracy of 1x10-4 g/cm3 with a compact design. The L-Dens 437 E model connects to an evaluation and display unit which calculates several parameters including: density, specific gravity, concentration of various acids / bases, and various other units based on density. The evaluation unit also provides Modbus, HART, various other bus communications, and 4-20 mA outputs to make connection to any flow computer or PLC extremely easy.

L-Dens 4x7 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 and/or phase separation
  •     Product blending
  •     Quality control
  •     Fiscal measurements / custody transfer
