Model Number: XL7-HT
The XL7-HT viscometer is available as a range of standard models, but can also be adapted to suit any special application – all with the same features and benefits:
- High accuracy and sensitivity
- Simple installation
- Virtually maintenance free
- Resilient to process conditions
- Any tank or pipe size
- Any process connection
- Digital and analog output
XL7-HT transducers are designed to work right in the heart of the process. They are not affected by pipe/tank size or upset by gas or air bubbles. Installation and operation are quick and simple, and should not require any special training or skills.
Practically any process coupling can be factory fitted to your new viscometer, ranging from flanges and threads to hygienic RJT, IDF and tri-clamp fittings. Simply specify at the ordering stage.
An XL7-HT viscometer can be mounted in any orientation and supplied with virtually any process connection to suit your needs. The instruments require no special pipework or additional infrastructure – simply bolt on, supply power and you’re ready to measure viscosity. Calibration is maintained whatever the circumstances, so no on-site transducer recalibration is necessary.
The VP550 Signal Processor is connected to the XL7 transducer via a simple 3-core cable and provides all display and signals for plant operation. Transducer and processor can be mounted up to 3 km apart; 4-20mA and serial data outputs allow for direct connection with recording and supervisory equipment for viscosity monitoring and control.
XL7 viscometers are frequently used as part of an automatic viscosity-based process control feedback loop.
- Tank or pipe mounting
- Operates in any orientation
- No special pipework
- No pumps or bypass piping
- Any process connection
- Cable length up to 3 km
- No on-site calibration
- Easy fitting
Cool Heads, Hot Toes
Continuously measuring viscosity at high temperature requires a special breed of viscometer. The XL7-HT model is capable of direct process viscosity measurement at up to 450 degrees C (842 degrees F) without the need for cooling jackets or ancillary pipework.
Special transducers are available for even higher temperatures.
We like to let the sensor get hot. Nothing affects viscosity like temperature, so the measurement must take place at the actual fluid temperature. Try and cool the sensor and you’ll cool the fluid, leading to large errors. The thermally efficient design of these viscometers allows the sensor to take the full heat of the process while keeping the electronics comfortably cool. The result is unparalleled accuracy even at the highest process temperatures, with no messy cooling system to bother with.
