The SIKA VTM 15 turbine flow sensor is made for flow measurement or dosing applications for liquids. Because of the very compact design, the extensive measuring range and the convincing precision of measurements, almost unlimited applications are possible. The sturdy bearing materials – sapphire and tungsten carbide – also guarantee an exceptionally long endurance. The liquid flowing into the SIKA VTM 15 turbine flow sensor is split into individual jets by the guiding blade. These jets hit the rotor evenly from different directions, setting the rotor in motion. The rotation speed of the rotor is then converted to an electrical pulse signal (frequency): The rotor is fitted with magnets and a Hall effect sensor detects the rotation of the rotor. A flow-proportional frequency signal (square-wave signal) is made available. The construction of the guiding blade and rotor enables to realize the very low start-up flow values.

The WIKA GLS-1000 float switch has been developed for monitoring the levels of liquids. It combines the advantages of the proven and robust float-based measuring principle with modern digital switching technology with PNP and NPN output signals. The WIKA GLS-1000 float switch is suitable for a multitude of media, such as for example, oil, water, diesel and refrigerants. A permanent magnet built into the float, through its magnetic field, activates the semiconductor sensors built into the guide tube. The switching operation is contact-free and free from wear. Since no mechanical switching process is triggered, the sensor offers an unlimited number of switching cycles. Depending on customer wishes, the switching functions of normally open and normally closed can be realised as PNP or NPN outputs for the defined switch position.
