Page 4: Regulation Use
4. Regulation Use The model DSV is employed for the measurement and monitoring of liquid flows which are homogeneous, free from impurities and have a low viscosity. In addition, they must be compatible with the materials used in fabrication of these units. -
Page 5: Operating Principles
5. Operating Principles The proven KOBOLD flow meters and switches model DSV are based on the principle of the well-known float-type flow meters except for the conventional tapering measuring tube. These patented instruments are provided instead with a cylindrical flow tube with conical slots around the periphery. -

9. Commissioning Application in machines, according to guidelines 89/392/EWG, the commissioning of these units is barred until it is determined that the machine is in agreement with the designations of guidelines. Adjustment of limit-values Loosen both safety screws on the contact base clown, with the help of a screwdriver. -
Page 17: Maintenance
Hysteresis Hysteresis reflects the difference between switch-on and switch-off points of a contact. Through standard tuning of the float magnet and reed contact power (AW number) a hysteresis of about 3-5 mm float stroke is achieved. Thereby, ensuring that the contact exhibits bistable behaviour. Exceeding the measuring range Attention! Continuously exceeding the measuring range, especially with pulsating flow and the resulting contact of the... -
