Model Number: VJ1
The ViscoJet process viscometer offers an intelligent sensing system for continuous on-line/in-line viscosity measurement in process control environments requiring high resolution and accuracy with excellent repeatability. Ready for use straight out of the box, the ViscoJet VJ1 is a high-performance stand-alone device that can be connected directly to a PLC or DCS for real-time viscosity monitoring and control. Storing all instrument-specific data on the sensor itself gives complete flexibility of installation while facilitating on-the-spot performance monitoring and optimization.
- Stand alone operation
- High sensitivity and repeatability
- Integral temperature sensor
- No moving parts
- No maintenance
- Spigot mounting installation
Unaffected by vibration or flow conditions, the ViscoJet is factory-calibrated to international standards traceable to NIST, which means that the device is shipped ready for immediate use with no need for field calibration.
Viscosity can be measured for almost any Newtonian fluids whether they are moving or at rest. In addition, the ViscoJet is ideal for most non-Newtonian fluids because its high shear rate results in highly repeatable measurements that aren’t affected by flow rate changes.
The robust orientation-independent sensor has a solid construction with no moving parts, seals or bearings, so routine maintenance is not required even under difficult process conditions. An integral thermometer provides simultaneous measurement of fluid temperature, allowing calculation and real-time display of viscosity corrected to a reference temperature.
Operating on any supply voltage between 12 and 24V DC, the ViscoJet provides a 4-20mA analog viscosity signal and a more comprehensive RS485 serial data link.
The associated PC-based ViscoLink software has a user-friendly interface showing live viscosity, current temperature and temperature-corrected viscosity and the data can be exported to Microsoft Excel for logging and analysis. ViscoLink provides instant access to a complete set of diagnostic parameters for instrument validation purposes, thereby minimizing the time, effort and cost involved in any regulatory assessment of calibration and condition.
Installed in minutes, the ViscoJet inline viscometer offers an immediate, reliable and durable solution to the challenges of real-time on-line viscosity measurement on any process line.
VP Processors provide a local display and an array of useful outputs for recording or control. The ViscoJet can also be directly connected to a PC, laptop or tablet for continuous or occasional viscosity monitoring, as well as user configuration of the various sensor functions.
VP Processor Connection
The ViscoJet sensor and VP550 Processor may be linked by standard 3-core signal cable over a distance of up to 1000 meters. Analog 4 – 20mA and RS485 digital data outputs from either the ViscoJet or the VP550 can be connected directly to recording and supervisory equipment for viscosity monitoring and control.
Installation and operation is straightforward and should not require any special training or skills.
