KOBOLD Instrumentation claims their KOBOLD KZA gear wheel flow meter reduces mechanical wear to a minimum, because the rotations can be read off contact-free, externally through the housing. The measuring device in a robust aluminium housing can tolerate a pressure load of up to 160 bar and is perfectly suitable for the measuring of viscous media.
Five types with different dimensions cover measuring ranges from 0.02…4 l/min to 1…200 l/min. The viscosity can range from 20 to 4000 mm²/s. With a viscosity range of 1 to 3000 mm²/s, a particularly high-quality model equipped with a ball bearing is offered, which reaches an accuracy of 0.3% of the measured value.
A pulse output informs about the current media flow. Furthermore, two powerful evaluating electronics are provided. A very good readable display on site is one of the characteristics of the plug-on LED-display.
The indicator is located between the plug and the base. An easy operation via two buttons can be carried out without problems on site. As output signals, a 4...20 mA output, a pulse output or a relay output are available. The robust plastics housing is designed according to protection class IP 65.
The separation of evaluating electronics and sensors allows comfortable remote monitoring and display away from the measuring point. The evaluating electronics offer various possibilities for adjustment and evaluation, including dosage.
