Process viscometer
0 - 100 000 cP | VP-2000 Marimex Industries Corp.

The ViscoTron VP-2000 combines the flexibility of the VP-3000 with the drive mechanism of the VP-1000 to provide a sensor, which will satisfy many process applications at a lower price point.

The series VP-2000 is available in versions to measure low, medium and high viscosities. Sensors can be constructed for pressures up to 40 bar (340 psi) and temperatures up to 275˚C (530˚F). A PT100 inside the sensor bulb measures the temperature of the process.

Calibration with Newtonian ASTM traceable fluids over 2 decades is standard with 3 decades optional. The sensor is gravity independent and therefore can be mounted in any direction.

The viscometer measures the drag of a fluid at the surface of the torsionally resonating sensor. The constant amplitude twisting motion creates a shear wave . Speed, direction and turbulence of flow have no influence on the measurement. The resonant frequency is dependent on the mechanical construction of the sensor. The microscopic motion is fast enough not to be influenced by outside mechanical vibrations, yet low enough to provide excellent sensitivity and resolution even for non-newtonian fluids.

The neck is designed such that the sensor will work reliably without air cooling in process temperatures up to 175˚C (350˚F) or 275°C / 530°F respectively dependent on the length of the neck. This ensures that the the sensor is kept at the actual process temperature.

The sensor is compatible both with the traditional ViscoScope VS-4450 transmitter and the ViscoTron direct digital drive transmitter VT-G130.
